The other day an acquaintance mentioned to me that he'd like to start a new business in the computer forensics trade, and make it his new life's work. Does that make sense? Well, sure it does, and just because everything is moving into the cloud, or so it is predicted doesn't necessarily mean that folks who are trying to hide something would dare to store stuff there. After all, it would be easily searchable by the authorities, or some NSA searching algorithm will find it.
Thus, those using computers to help them break the law are more likely to keep information close to the vest on encrypted CD ROMS, hard drives, thumb drives, etc - kind of like Osama bin Laden did. And then there is another aspect to the computer forensics business, and that is recovering lost data for businesses. Therefore, I explained to him that I agree that computer forensics, and consulting are a good business to be in - smart idea.
In fact, I have a friend who had a computer consulting business, and did quite well, but had challenges when he took on the wrong partner, and they both had different ideas on how to run the business, so they split it into two, hardware sales/computer repair and consulting/networks. Just be careful if you take on partners, was his advice. I'd say that advice would definitely go for the computer forensics sector as well.
And, speaking of computer forensics, I sure could have used him a few years ago, when my hard drive crashed, and I lost 4 eBooks I was working on, which like a dummy I hadn't backed up. That was terrible. And that same year I had my MS operating system screw up, and when I re-booted I lost a ton more, lots of import ideas, concepts, and half completed articles I was thinking on. People really need computer forensics, and data recovery, and Corporations really need to trace back how the hackers get in to provide safe data security too.
I'd say there is a ton of work to be done + potential contracts with law-enforcement I'd say, as well. Good be quite a lucrative business I'd say? Indeed, maybe my acquaintance is quite wise in his desire to start such a business, maybe that is a smart industry to get into, and with the right connections, it ought to be a very awesome business. Well, that's all for now, something to think on. If you have any more questions or comments on the computer forensics industry please shoot me an email.
Lance Winslow is a retired Founder of a Nationwide Franchise Chain, and now runs the Online Think Tank. Lance Winslow believes writing 23,777 articles by 7 PM on June 27, 2011 is going to be difficult because all the letters on his keyboard are now worn off now..
Computer Security is something large commercial organisations have long since realised cannot not be ignored. SME's (Small and Medium-sized Enterprises) are not always so diligent, this is often down to the lack of resources or the simple fact that no one in particular has sole responsibility for it. Sure, it should be part of any IT function, but with all the other more pressing day-to-day demands it is also something that sits untouched on a 'to do list', if it even makes it on to the list at all.
Then there's the home and personal users who in most cases just don't understand the dangers. Any thoughts regarding security stop at the purchase of some antivirus software or a possible reluctance to use a credit card online in case it is compromised. The thought of having to stop hacker intrusion of their computer may never have crossed their minds.
Computer security should be a concern for everyone with a personal computer or laptop, from the home user to the world's biggest corporations - they all have good cause for concern. The readily available supply of both hardware and software keyloggers is making it easy for the cyber criminals to gain access to sensitive and potentially harmful personal and corporate data.
I'd just like to make one thing clear. Keystroke recorders, or Keyloggers as they are also known, are legitimate surveillance hardware or software methods which are completely legal. How can that be? I hear some of you say. Well, it is important to distinguish between legitimate and fraudulent / covert use of these devices.
As a legitimate surveillance tool Keyloggers are often used by employers to ensure employees use work computers for business purposes only. Keyloggers can record instant messages, e-mail, and any information an employee types using their keyboard. A log file of keystroke activities is created by the keylogger which can then be sent to a specified receiver for examination. Some keylogger programs can also record any e-mail addresses the employees' use and Web site URLs they visit. All activities are logged into a file, supported with screen snapshots.
In cases of under performance an employer may use this method to check on an employee's activity - it may expose time wasted on web surfing, instant messaging or time spent on social networking sites, time which should be spent working.
Parents worried about the safety of their children when online can use keyloggers to monitor their activity. I know this may raise huge questions about trust, but parents have to balance this against the potential dangers presented by the unscrupulous and devious in our society who try to groom children for unsavoury purposes. It's a hard fact of life but there is a category of low-life who prey on the young and unsuspecting. If using this technology gives a parent peace of mind and ensures their kids stay safe then I regard it as a legitimate use.
Key logging recorders can be small hardware devices - small and usually unnoticed hardware keylogger devices inserted between the keyboard and the system unit can record every single keyboard input. A microcontroller interprets the data, and stores information in memory and just like a USB key drive will retain information even without being connected to a power source. Some of these devices can store up to 12 months of data entry. Every account reference, every password can be recorded. These hardware devices are quick and easy to install, just plug them in. They can also quickly be removed or moved to another computer.
Keyloggers can also be a software program which resides inside your system - a much harder thing to spot. I've seen some software versions advertised as a means to catching a cheating spouse or partner. To some people the suspicion that they are being cheated on can cause great heartache and anxiety which eventually becomes unbearable. In such cases they may invest in a product which may tell them one way or another if their suspicions are valid or not.
There are clearly legitimate reasons why people use keystroke recording methods as part of a security or surveillance activity. However, this also raises the question of what can happen when the criminal element use these methods on the unsuspecting computer user.
A physical security search of all computer hardware to identify the presence of hardware keylogger devices may seem like a tedious task - it is, but then again compare this with the theft of important data and the potential consequences if this found its way into the hands of the criminal fraternity. Perhaps that search wasn't so tedious after all.
If being used covertly hardware keyloggers have to be deliberately connected by someone who has physical access to the computer in question. Software versions do not! It is the software versions which give rise to the greatest concern.
Users may unwittingly download the software version when visiting a website or when they download other legitimate content from the net. The software version can sit undetected hidden somewhere amongst your system files capturing every keystroke you make and relaying them to someone who could be anywhere in the world. That's every password, credit card number, bank details etc. - everything a criminal would need to start spending your hard earned money.
It's the software version which is the real threat to the general personal computer user. The easy target that is unlikely to spot they have become a victim and who won't know how to stop hacker theft of their information. Who has never even heard of Keylogger Removal software or how to use it. These are the easy prey for the professional computer hacker.
For anyone who wants to read more about Keylogger Removal I invite them to check out my Blog on the subject: [http://www.keyloggerremoval.biz]

Julian Assange, the assailed WikiLeaks publisher, was allegedly supplied with a huge quantity of sensitive information which is now showing up on the infamous WikiLeaks website compliments of a private first class in the Army. Uncle Sam is screaming foul. Most people are scratching their heads trying to figure out how such a thing could happen.
The real truth is that we likely did it to ourselves. There is a full range of possibilities but a PFC isn't likely to have broad access to a large cross-section of secret information. The application of flawed network security policies, however, probably made it possible for Pvt. Bradley Manning to allegedly gain access to the information now appearing in Wikileaks.
You may recall that after Al Qaeda's attack on September 11, 2001 an investigation was launched. One of the findings was that U.S. intelligence information was too "stove piped". The criticism was that each agency with a security function gathered and guarded its own information rather than sharing it with other agencies. Efforts to tear down the walls among agencies were implemented. Intelligence agencies were told to distribute their information. The very office of the Director of National Intelligence was created to ensure giving out information among agencies.
The groundwork was laid for massive security leaks to happen, especially the loss of information that is stored in electronic databases. Computer operating systems have network security settings associated with them. These are known as "policies" and they determine who has authorization to what specific information. The principle of "need to know" is generally applied. That is, if a person is without the need to know the information, he or she is denied access to it. Each employee would have differing levels of access to sensitive information.
The U.S. State Department sent over the information it was told to send over to the Defense Department. Did the State Department set the security policies to be applied to DoD? It's unlikely. Would the information to which the PFC gained access ideally be controlled by the need to know principle? Yes, but the information arriving at DoD was unlikely supported by strong network security policies as to "who" within DoD could have access.
On the other side of the coin the DoD was likely without the resources needed to establish fine granular network security policies for control on each and every sensitive piece of information arriving from the State Department. The forced sharing of information between multiple agencies would likely increase vulnerabilities and produce system failures.
A PFC might very well have been able to download and review information if robust network security policies were absent. Any efforts by multiple agencies to match up sensitive information and establish need to know policies would be extremely difficult and time consuming. Couple this basic fact with the apparent desire on behalf of the perpetrators to harm America and we have a recipe for disaster.
The real enabler may have been our own ill-configured network security policy settings and the likes of Julian Assange who is allegedly linked to the globalist organization Open Society.

Almost everybody today has a personal computer connected to the Internet. The internet is a great way to communicate, gather information, and shop. It has made life easier with applications that help a person transact over the internet. However, while the internet has numerous advantages, there are serious disadvantages that should be taken into account as well. The internet has become a breeding ground for criminals and hackers who victimize people by accessing their profiles and fraudulently use their names for transactions which result to huge amounts of bills and tainted credit records of the victimized people. Thus the need for an efficient and effective internet security that could help protect your identity from these attacks. Using a firewall protects your computer and prepares your computer from potential attackers.
Facts about firewall security
1 - A firewall is basically a piece of software or hardware operating in a networked environment to prevent communication between areas with different degrees of trust. The term firewall is derived from the same concept of firewall used in construction whose purpose is to keep fire from spreading if a fire starts.
2 - Personal firewall is the most common type of firewall and this type is found in Windows XP. This type of firewall was not popular among users because of the invention of the viruses-Blaster worm and the Sasser worm. These worms drove Microsoft to start designing a more comprehensive firewall application that can provide users improved and enhanced protection for both their home and office networks.
3 - The next generation of Microsoft firewall protection is effectively designed to help secure and equip both your personal and business computers with the advanced protection against the capabilities viruses. The next generation of firewall protection allows you investigate any activity going on outside of your system. It will let you know who is accessing your information online and who is doing transactions under your name.
Setting firewall
Every personal computer needs a firewall for complete cyber security. Luckily, there is no need to buy it since the operating system of your computer has already included it. Your role is to find out how to properly set up your operating parameters and start configuring your firewall by identifying what to allow and what to ban on your computer.
Although you could easily look for help in setting up your firewall in your computer, it is also important that you ask for assistance of somebody who knows a thing or two about firewalls. Mishandling of firewalls will make them useless and will not protect you from any cyber attack.

Social networking (SN) was a concept originally founded for the masses to use on a very overlapping basis, but alongside the acceleration of Enterprise 2.0, things have begun to pick up, and fast. After social networks surpassed the sustainable monetization stage the first Web 1.0 companies couldn't, and evolved to an adequate scale and spectrum, the next, less generic step formed: professional use.
Once enterprise discovered the potential for a means of fast, accessible and affordable communications between remote workers, professional networking began to grow out of the single all-inclusive concept which generically encompasses SN. There are, or at least were, some obvious benefits of using Facebook and Twitter to share data and information, notably the fact no training was required for employees already accustomed to the simplified user interfaces via their own personal experience.
However significant, this use by the enterprise was only one aspect to professional networking, which branched out to encompass other fields as well. These include individual employment of LinkedIn and similar services. And, as SN geared more and more user interest, enterprise focus began to fall on two very specific elements.
Social Media Monetization
The major social networks alone, namely Facebook, Twitter and the ever-fading MySpace, have over a billion users combined, and they're not the only ones to monetize these demographics. Enterprises utilize various SN resources, including advertising, dedicated channels, metrics and Big Data to boost marketing and consumer perception. There are many examples of enterprises utilizing social media for outbound purposes, but internal use represents the second, equally significant element of the two noted above.
Internal community platforms
In addition to marketing, enterprises also adopted social networking for internal communications between remote workers. However, employee communications and collaboration requirements drastically increased, and general public-optimized social networks were abandoned in favor of specifically targeted enterprise-centric offerings.
Demands which were not answered by Facebook and Twitter were addressed and compensated for in these new offerings, which multiplied in number. Security, transparency, integration and functionally were all drastically enhanced and optimized for the enterprise, resulting many, relatively still fresh products.
Cisco, IBM, Jive, Hearsay and dozens of others are all now competing for market share in what was once only an almost makeshift market. Increased competition means enhanced offerings. In terms of internal social networking platforms, this translated into blogs, document repositories, calendar integration, project planning, instant messaging, video conferencing and VoIP options on a massive scale.
What goes around comes around, and after insufficient features were replaced by complex functions and capabilities, the need for simplicity and clarity soon realized itself.
Internal enterprise social networking offerings are often fairly complex, sometimes one or two steps exceeding efficiency. A large bulk of only partially necessary functions has some very obvious downsides to it, most notably when it comes to organization and time consumption on the user. Research firm Gartner predicts that social networking will replace e-mail as the main communications channel for 20% of business users by 2014. Nevertheless, growing demand doesn't mean the necessity will be properly answered. Enterprise social platforms are not designed for socializing, and highly popular social network add-ons are simply not designed for large-scale business users. Another factor is training, and a complex internal community platform probably is not worth the training time it would require.
Simplicity is a requirement for internal networking, and it's this factor which can turn a piece of enterprise software into an advantageous operational asset for a given company and workforce. Legacy software integration, large-scale real-time collaboration and communication channels cut down to the simplest and most scalable form derived from actual user experience form a more realistic structure, and are already utilized by existing offerings.
Overall, enterprise social network offerings still need some time to mature. On the bottom line it's all about boosting workforce efficiency and answering corporate needs, and social networking may not be the answer. Gartner predicts that while 50% of enterprises will use social networking activity streams next year, they will have less than 5 percent penetration. Moreover, 2012 will be the year "over 70 percent of IT-dominated social media initiatives will fail", and only 25 percent of enterprises will routinely utilize Big Data from social networks by 2015. All and all, it's all about necessity and practicality. The answers to these will probably be shaped around mobile and cloud computing, as these continue to integrate directly into business operations at an ever-accelerating pace and maximize corporate assets.

Using internet applications is great fun but they are sometimes unsafe and susceptible to unauthorized access, security threats and the inability to access inbound and outbound traffic. Sometimes you may also face the stealing of some crucial information and the interruption of some unauthorized software which consequently hampers your software and increases the security risks. Making use of internet security firewalls is the best way to protect your computer.
With firewall security you can stop unauthorized access to the network or internet by allowing authorized communication to take place. If there is an attempt to access the network or internet, it allows the user to block and encrypt the attempts which are blocking them. It is one of the ways to remain safe from viruses, Trojans or malware, which repeatedly continue to interfere with and connect to the internet or network. A typical firewall works only one way by keeping vigil on inbound traffic; for example, Windows XP and Vista, which are unable to control the multiple threats. So it is better to install the two-way firewall that checks both the inbound and outbound traffic. Such a firewall allows the creator to manipulate the system while recording the keystrokes, including internet banking accounts and keywords and send those logs to the creators. The two-way firewall works at the Intrusion Detection System which initiates an outbound connection.
The best firewall can block different ports through which an unidentified logger can seek information from your system by blocking unauthorized traffic online. So if you want to minimize the threat, use the best firewall protection software. One should select the appropriate firewall security system/software that should be compatible with your system and should provide the best internet security.
You will find many antivirus companies that can also provide firewalls. They can be disabled or reinstalled according to the user's desire. For complete internet security, you can install a firewall in every computer in the network. The added benefit of it is that if any one of the computers is being infected with viruses, it cannot be spread to the other computers in the network if each and every computer in the network is protected by the firewalls.
The function of firewall security is very simple since the mode of communication in the network is transmitted into small packets and these packets are equipped with both the originator of the message and the receiver of the same. The firewalls installed can determine the type of application message and properly assemble it to find whether the originator is authentic or not.
Therefore, the basic function of the firewalls is to protect the computer from unauthentic and illicit networking and thus provide the best network security.

Online computer security is overlooked or minimized by too many Internet businesses. There are numerous security software packages available. Each company offers a multitude of features to keep your business computer safe and secure. So which features are essential? Which ones can't you do without? Which of these features are already in your business computer? Most vendors sell the basic version of their security software and sell the premium versions (usually with the features that you really need) at a higher price. Is it worth it to pay more for the premium versions of these security programs?
To safeguard your online business computer the following are what you absolutely should have:
1. Anti Virus Software
Having an anti virus system installed in your business computer is a must as it will detect and remove viruses and worms that have gotten into your hard drive. You may accidentally download infected files, receive infected e-mails or have your system compromised after visiting questionable websites. Once installed on your business computer, your anti virus software will need to be updated on a regular basis since new viruses are created every day. Most anti virus software programs automatically update themselves.
2. Personal Firewall
Install a personal firewall on your business computer to keep hackers and malicious programs from infiltrating your computer and accessing your business files. A personal firewall will monitor connections that are coming in to and going out of your computer.
3. Anti Spyware Program
Install anti spyware program in your business computer in order to block or remove spyware and adware programs that have gotten into the computer. Spyware and adware programs are malicious programs with hidden code. They disguise themselves as acceptable files. For instance, rootkit programs are often used by hackers to hide spyware and malware.
4. Wireless Network Monitoring Software
If you use a wireless networking system this piece of software is absolutely essential. It will prevent unauthorized individuals from using up all your bandwidth or invading your wireless network. With wireless network monitoring software you can set up access IDs, passwords and network addresses.
The following are also good for security although it may not be as critical to have the best software available:
1. Anti Phishing/Fraud Defense Software
This security software protects your business computer against phishing and fraud. It stops various online fraud attempts to get your credit card number or bank account number. If you use Internet Explorer or Firefox as your browser, they already have this security feature integrated.
2. Online Identity Protection Software
Online identify protection software protects you from online identity theft. Most of the sites you will use for online purchases already have some type of online identity protection implemented. If you use your credit card or debit card for online purchases, be aware that it comes with online protection in cases of unauthorized purchases.
3. Anti Spam Software
An anti spam software filters e-mails you did not request or e-mails that may contain dangerous files. Web-based e-mail services like Gmail, Hotmail and Yahoo already have spam filters in place. If you mistakenly open an e-mail with a suspicious attachment or links to sites designed to steal your information, the anti spam software will scan the attachment first or disable the links so that you do not accidentally click on them.
4. Pop-Up Blocker
A pop-up blocker prevents malicious scripts in pop-up webpages from executing. Again, Internet Explorer and Firefox already have a pop-up blocker installed.
When you purchase any of these security software packages to protect your eBiz computer, make sure you keep your subscription up to date. Keeping your security software current helps keep your online business computer secure.
Most security software offers similar features and protection capabilities. There is, however, security software that is specifically recommended for online businesses. Most of this security software can be downloaded for free during a trial period before you purchase the full version.
Your business computer can never be 100% safe and secure. You can, however, lower the risk of unauthorized access to it by using security programs and keeping them all current. By doing this, you save yourself time and money.

Are you having problems playing sounds on your computer? There's no need to worry. That can be easily resolved by going through a little troubleshooting. Follow the steps below:
Are your speakers on? If you are using speakers, make sure that the power cord is firmly plugged into a working outlet and that the speakers are turned on.
Are your speakers or headphones properly connected? The sound cable of the speakers or headphones must be securely plugged into the appropriate jack on the computer. Look up your speaker/headphone documentation to be sure that you have connected them correctly.
Are the volume settings correctly set? Adjust the volume control to the proper settings on the speakers or headphones and on the computer itself. Make sure that audio is not muted.
Is the source media playable? You may be trying to play a damaged disk or a corrupt sound file. Try a different disk or sound file.
Are your speakers or headphones working properly? Try different headphones or speakers. The ones you are trying to use may be defective.
Is your sound device working properly? Your sound device should be enabled and properly configured. If you have more than one sound device, the device you are trying to use should be the default sound device. The documentation that came with your sound device will provide information on how to enable and configure it.
If your sound device has been properly enabled and configured and seems to be working properly, yet you still can not hear sounds, or if you can not configure your sound device on your system, it is most likely due to not having the correct device drivers.
Device drivers are programs which add functionality to devices. These are software that make hardware devices work. As with all other programs or software, device drivers need to be compatible with the platform or operating system on which they are to be used. A device driver designed for a MAC will most definitely not run on a PC. And drivers made for Windows 98 will not work on Windows Vista. For drivers to make any device function properly, the correct version for the particular system must be installed.
When you buy a computer, the correct drivers are usually already installed on it and a driver installer disk or a recovery disk usually comes with it. There are circumstances wherein the drivers are lost, most of the time because of a system crash. Reinstalling the drivers from the disk that came with the computer would solve this. But what if the disk has been damaged or lost and the computer is already beyond warranty? Or what if the system was upgraded so that the device drivers that came with it no longer work with the upgraded system?
Again, there's no need to worry. That can be easily resolved by using a driver finder program. A good driver finder program will scan your computer, identify hardware devices installed on it, recommend drivers specifically made for the brand of your computer, and download the most up to date drivers for your devices. It should preferably have a feature that will allow you to copy the downloaded drivers to a CD, network drive or USB flash drive. An option that lets you download the program and scan your computer for free would be an added bonus.
There are many driver finder programs on the market. You can search the internet and choose one which will work best for you.

So you want to know just how secure your computer network is. You can't really tell until you perform a text which assesses your system's weaknesses and how these could be taken advantage of. Companies and personal users do these tests so they can narrow down their locus of problems regarding their systems and come up with possible ways to remedy whatever irregularities are spotted. In a way, these so-called "Penetration Tests" are synonymous to ethical hacking which aims to get into a system to see how it can be further strengthened and guarded against black hats.
Doing a penetration test will, of course, begin with a plan where goals are defined as well as the time limits for the achievement of those goals. Here, the major problems will be discussed, as well as the specific parts of the system that should be tested, when and how long the process will take. Basically, this is where the structure of the test to be performed will be mapped out, beginning with pinpointing the actual potential sources of problems and the approach that will be used to solve them using the penetration technique.
Once everything has been detailed out, the role of the ethical hacker will be defined. The person who will pretend to be a hacker will now put himself in the shoes of a black hat and will try to do things as a black hat would to a system that he plans on attacking. After this, the tester will now go through the system and see from which actual points a hacker might possibly attack. In other words, this is where vulnerabilities of such a system will be exposed.
The last step is for the tester to "hack" the system as though he was a real hacker with real objectives for doing the hacking. For example, the tester would try to dig as much information from the system as he can. By knowing how this is possible, he will be able to come up with counter measures that will make such an intrusion impossible.
After the test, a report will be submitted to the company and will detail whatever vulnerabilities have been discovered with the system as well as how to best remove these weak points by providing solutions. In other words, the main goal of a penetration test is to see where a hacker might be successful in hacking a computer network and provide solutions to make sure these weaknesses are fixed before a real hacker makes a go for them.
Prevention is still, of course, the main thing when it comes to avoiding hackers. Companies must make it a point to ensure that their employees only visit clean sites or, if this is not possible, web surfing other than those directly related to the job, should be prohibited. However, as one can never totally get rid of the threats of hacking, it would be wise to install a software that isolates such risks significantly.
An IP change software, which allows a computer to go online with its real IP address hidden, could be a very good option. When the IP is hidden, any computer can run around freely on the Internet without being targeted for hacking. Or the computer may be targeted but the hacker's efforts will simply be in vain because such computer won't really be accessible to him since it's using a fake IP.
For safe surfing, surf anonymously and preserve your online security.
Since firewalls are so commonly used it is worth exploring them in greater depth. Corporations often set up rules for managing their Web connections using firewalls. A firewall enables a company to designate how all end users can use their network and decide what information is passed through Web servers and other servers.
There are several methods a firewall uses to control traffic that comes into and goes out of the network. One way firewalls do this is through packet filtering. During this process a firewall analyzes small packets of information against pre-designated filters. All data is sent via small packets of information through filters. Safe information is passed through and unsafe information is generally removed.
Another way firewalls mitigate traffic is through proxy service. This means the firewall retrieved information from the Web and sends it to the requesting computer. Still another method of traffic control used by firewall is stateful inspection. This technique allows the firewall to compare certain parts of the data packet to information gathered from trusted sources. Information going to the firewall from the Internet is monitored to determine whether it contains key characteristics that suggest the information is safe rather than harmful. Information designated as safe passes through freely and other information is blocked.
The methods a company selects will depend on a number of factors including personal preferences. Regardless of the method a firewall uses however a company or network administrator can customize the firewall to filter information based on a pre-established set of criteria.

2011 is turning out to be busy for those involved in information security, so far there have been the following information security related incidents in the headlines during the first 5 months of the year:
February 2011 HB Gary hack attack by the group known as Anonymous.
March 2011 RSA hack stole token data, (attackers were reportedly advanced persistent threats).
April 2011 Sony hack data theft reportedly involving information related to 77 million accounts and 2.2M credit cards.
April 2011 Epsilon victimized by a hack attack, email addresses stolen.
WikiLeaks related attacks perpetrated by the group known as Anonymous.
April 2011 Ritz-Carlton Hotel customers data stolen in a hack attack.
April 2011 Amazon Web Services cloud outage (non-availability).
May 2011 Lockheed Martin (details were not disclosed).
May 2011 Woodside Petroleum (Australia's largest oil company said attacks were coming from everywhere).
May 2011 Public Broadcasting (a phony news story and lists of reporters accounts and passwords were posted to a PBS site.)
May 2011 A New York Congressman reported a lewd photo had been mailed when his Twitter account was hacked.
Hacking is a type of directed attack typically executed by an external human using tradecraft methods to exploit accessible vulnerabilities and inflict damage. Protection methods are usually applied to limit the damage inflicted during an attack, limit the duration of an attack or deter an attacker. The effectiveness of any protection measures in use is clearly at issue when a successful attack occurs. Forensic tools and methods are used to analyze attacks allowing lessons learned to be captured and documented. Data theft is often motivated by financial gain, focused on credit card data for sale to fraudsters or email addresses for sale to spammers.
Non-availability incidents occur for any number of reasons, often not involving malicious activity. Such incidents can grow as related resources cascade into failure, a phenomena with potentially wide spread impact.
The Internet is often used to deliver the attack. The nature of giant public networks facilitate anonymity while being reliable and predictable.
The list does not include a huge number of incidents based on malicious code that have become common events or the large number of incidents involving sensitive, typically government, sites that never make it into the press.
The rapidly evolving sophistication of hacking attacks is a cause for concern. State sponsored activity involving "Advanced Persistent Threats" is emerging from behind the curtains as a valid concern for enterprises worldwide. The press in not likely to suffer from a shortage of material for their headlines for the remainder of 2011.
The incidents mentioned are from press articles that can usually be found in the publisher's archives. A search using the name of the victim and "hack" can often find a no cost article.
Many companies are turning to IT managed services for help with keeping their data secure. If a security breach were to occur on company computers and servers, sensitive information such as personal client and employee information, trade secrets, or financial records could be compromised. This could lead to the loss of integrity of the company as well as loss of client trust.
This is where IT managed services come in handy. They can help with making sure servers and networked computers communicate with each other and with the outside world in a safe and efficient manner. More specifically, they can aid in ensuring that your networks, servers, and computers have the latest security software, can fend off malware and viruses, and can be protected overall from information security threats.
Types of Information Security Pitfalls
Here are some of the typical risks a managed services provider can help mitigate:
Attacks from virtual threats. If you use a hypervisor machine (the virtual platform that hosts operating systems), you must make sure to keep its security measures up to date with the latest patches because it is possible for it to be attacked from within the virtual world. If that attack were to occur, all of your servers would be compromised.
The transfer of harmful data packets onto your servers with your knowledge is another viral threat that your company may face. A managed services provider can set up virtual firewalls that will create boundaries between each server and will prevent servers from communicating with non-secure servers.
Lack of network oversight and mindfulness. When hiring an IT managed services professional, a clear line of security responsibility is set so that you and your employees can focus on your own tasks at hand instead of worrying over who is responsible for the company's information security.
Virtual sprawl. It can be easy to keep creating new servers when a company has virtual servers (even when you don't work in the IT department). When more servers are created than being tracked is when a virtual sprawl can occur. This leaves the virtual server susceptible to being attacked from outside forces (hackers). If a server is deliberately created and then forgotten about, the information on it may be at greater risk of being compromised.
IT managed services will help your company create only the servers it needs. A managed services provider can also help prevent virtual servers you aren't aware of from infecting your other servers by installing and updating security patches.
How an Experienced IT Managed Services Company Can Help
An IT managed services firm can help improve and maintain your information security so that, even though a virtual server is out of sight, the security maintenance needed to keep your business up and running is not forgotten about.
A managed services provider can do the following for your company:
-Install, maintain and update security systems on each server and computer.
-So that you are aware of the type of information the servers share, they can set up server scans.
-To help ensure that each new server has a purpose, they can design server-creating protocols.
-Without the proper formatting, a security patch will not be able to protect your server against attacks. Therefore, they can correctly install security patches.
The security of your network is highly important for your company. An IT managed services company can provide the proper support and security monitoring you need in order to prevent or address any potential issues before they impact the productivity, customer relations, and bottom line of your company.

Each time US Internet security software companies work with overseas companies, they end up risking the potential eventuality of giving away information which could be used against citizens in other nations, or used by country-sponsored cyber attacks on US computer systems. The risk is so great in fact that it is amazing that there isn't more oversight than there already is. Let's take a look at a recent case study involving Symantec and Huawei Technologies in China for a moment.
There was an interesting article in the New York Times recently on March 26, 2011 titled; "Symantec Dissolves a Chinese Alliance," by Nicole Perlroth and John Markoff, which stated;
"Less than four years after Huawei Technologies and Symantec teamed up to develop computer network security products, the joint venture is being dismantled because Symantec feared the alliance with the Chinese company would prevent it from obtaining United States government classified information about cyberthreats."
Anytime a very well market penetrated company such as Symantec gives clues, consults, or works with a foreign company, that foreign corporation now has more insight as to how the software that Symantec deploys protects their customer's computer systems. Therefore, we now have a big problem. You see, the software engineers and computer scientists working for Huawei Technologies, which has been set up much similarly to AT&T, are not stupid people. Many have been trained in the top US Universities in fact.
You see, they already know most all of the tricks of the trade to Internet and computer security, as well as all the neat strategies for encryption, thus, giving them more information, actually has the potential eventuality of rendering all US computer security obsolete. Not to mention the reality that in the end the Chinese will have copied all the intellectual property and the company doing business there will not have gained much anyway, expect for giving away their yesterday's and most likely a good portion of their current technology without any huge financial gain for their troubles.
US companies should be quite alarmed at what is happening, and be prepared to hyperspace any current technology before sharing any of it with China who really doesn't culturally respect what we in the US refer to as proprietary information or intellectual property. Okay so, why did Symantec kill their Chinese alliance so abruptly? Well, why do you think? Further, I ask; are a good number of the attacks on US Computer systems due to perhaps, should I go so far as to say; Unholy Alliance? Time will tell and the truth always comes up, no matter how well encrypted. Please consider all this and think on it.

There are many types of malware, malicious software that pose threat to your computer security. These malicious objects have been designed with the intent to disrupt the normal use of your PC. Cyber criminals, known as hackers use these tools and employ various techniques to invade your privacy and cause you significant personal and/or financial harm. Malware get installed onto your computer via various sources like web browsing, instant messaging and peer-to-peer file sharing. These malicious objects pose great danger to your online computer security.
Viruses are the small piece of software program that can install itself and infect a PC. Viruses have potential to infect and corrupt files. Even sometimes, hard drive can also be crashed by viruses. These can spread via any medium while exchanging of digital data in a computer network. These include DVDs, CD-ROMs, USB keys, etc.
Spyware is another common malicious object that poses great threat to cyber security. These are installed with some other type of desired program without the knowledge of the PC user. Once these malevolent objects are secretly installed they can change computer settings, collect your passwords, your internet browsing history and private information. Then this information is sent to the author of the spyware. How will you understand your computer is infected by spyware? Well, there are various symptoms. If you experience sudden slowdown of your computer, it might be due to spyware.
Adware is another very annoying type of spyware. If your computer is infected by adware you will experience tremendous amount of advertising in the form of pop-up advertisements or banners scrolling across your screen. This is truly disturbing and distracting but they don't pose that much threat like that of other types of spyware.
In the list of computer threats a worm is a notable name. This self-contained program not only can replicate itself but also use a network to infect other systems on the network. There are also worms that can secretly send documents though email to its author and even delete necessary files. Worm cause harm to other computers on the network as well as it consumes bandwidth. This means it slows down the computer and slows down web browsing.
To deal with cyber threats and enhance computer security you need to consult a tech support service provider. These service providers are highly experienced to cope with cyber threats. They will provide you with robust security so that you can stay away from all types of security threats.
Remote computer support providers offer PC security support at a very convenient price. Their services are available round the clock and you get state of the art services from certified experts.
Today's businesses expect a lot when it comes to their data networks. Speed, reliability, robustness, and scalability are just a few of the performance parameters with high standards from business users. One area in particular requiring special emphasis is security. Choosing the right network infrastructure is critical to ensuring that your security requirements are met end to end...and everywhere in between.
For example.... do NOT be so enamored with a traditional VPN backbone (e.g. Layer 2-based VPN services such as ATM and Frame Relay) that you overlook the drawbacks in maintaining the secure environment that your company applications will require. A standard VPN will not offer the same level of privacy and security as will a private dedicated backbone. At least not without extra effort on your part... and higher costs therefore in the long run.
A typical virtual private network (VPN) is a computer network that is layered on top of an underlying computer network. This is most commonly a public telecommunication infrastructure such as the internet. The private nature of a VPN means that the data travelling over the VPN is not generally visible to, or is encapsulated from, the underlying network traffic. Although it is run "layered" on top of a public pathway (the internet).... secure segregation of the two is enacted through using encrypted tunnels to ensure that data cannot be accessed without authorization.
The purpose of a VPN is to enable remote locations and/or individual users (e.g. telecommute staff) to access a company's network with some expectation of secure activity. An additional intent is to avoid the perceived high cost of owned or leased lines (dedicated circuits) that can only be used by one business. So, the goal of a VPN is to provide the organization with the same, secure capabilities, as a dedicated network. But at a much lower cost.
However that presumption is misleading. A traditional VPN network is not as secure as you likely expect and need. After all... it is still tied to a public infrastructure. A talented and persistent intruder can still defeat most encryption safeguards. Plus, a glitch in the hardware or software leaves your information open to public eyes. The appearance of failsafe privacy and security is really just that.... an appearance.
As for cost.... the price tag of the extra hardware and software to enable encrypted communication over your entire network is not cheap. Even though it may appear so compared to other options you may be considering. There's much more to the cost than set-up, installation, and encryption software. Don't overlook the maintenance, oversight, and trouble shooting of those safeguards. Particularly since you are responsible for all of that.... forever.... just to try and save a few pennies.
This is where MPLS comes in.
The architecture and protocols of MPLS (Multi-Protocol Label Switching) are predicated on the absolute privacy and security enabled via a dedicated network infrastructure. Put simply..... the entire network is completely separate and unto itself. You own it, share it with no one, and there is no connectivity of any kind with a public infrastructure. Now that is security.
To further drive home the main point of this entire article in simple terms..... with private lines or MPLS solutions, there is no path from the public into those network facilities. With VPN over the internet, the path is there and it's your responsibility to provide your own security. Think of the difference between a brick wall, and a brick wall with a door. VPN over the internet is the wall with a door, and you have to manage the lock and keys.
Once your MPLS core is configured and operating..... you're done. In fact it's unlikely you would even have much involvement with that. Your provider will do it all for you. Since it's a dedicated circuit network you are not responsible for the maintenance, oversight, and troubleshooting you would be with a VPN. In short.... it's hands off for you. No recurring costs except the monthly "leasing" fee for the lines comprising your network.
Before you play the cost card..... look deeper. The price of all dedicated circuits has been dropping dramatically for the last few years. Whether it's copper or fiber based.... the sticker shock days of old for dedicated T1 lines, DS3 Bandwidth, or SONET circuits (e.g. OCx) is long past. In fact.... probably the best deal for you today is pursuing MPLS over an Ethernet backbone. You'll get the best of both security and cost savings.

Computer forensics is a new and growing specialty that serves both the public and private sectors. IT forensics specialists are not only competent in software related matters, but in those relating to computer hardware issues as well. Computer forensics comes into play in both ethical and criminal issues, including intellectual property law, theft, and fraud. There was a time when those people committing computer crimes weren't at risk from the law - now they are.
These forensics follows traditional principles for scientific investigation. Work in computer forensics is systematic, well recorded and documented, and acceptable within a court of law. The methodology of computer forensics follows several steps. The first is to identify sources of digital evidence. The second is to preserve that evidence from loss, change or corruption. The third step in the process is to analyze the evidence, and the fourth is to present the evidence within the context it is required.
A good forensic specialist can manage the computer system and the data it contains while protecting sensitive evidence. Computer forensics explores both the individual computer, and any relevant networks or server connections. Forensics allows for the discovery of obvious and hidden data, as well as allowing access to password protected, encrypted and otherwise secured data on a computer system. Forensics may also allow for the recovery of deleted files.
As a matter of fact a lot of modern IT forensics work involves recovering files that have been deliberately deleted from computers and cellphones. The drugs trade relies on cellphones to communicate but now they're realizing that a good forensics team can retrieve information on every text message and phone call they've ever made.
You can think of these specialist forensic teams as like the ultimate data recovery specialists. No matter what lengths the guilty have gone to trying to hide the evidence of their crimes these guys can find it and use it against them in court. An example is the guy who set his laptop on fire but realized it was going to take forever to burn. So he threw the laptop into a river and figure that was enough.
It wasn't. Police were able to recover the laptop and almost all the data from his hard drive. He was prosecuted for the crime in question and is now serving his sentence. The only safe way to protect your data against a computer forensics team is to set the computer on fire, smash it to bits with a sledgehammer, put it in a container and have it shot into the heart of our sun on a rocket. And even then you can't be sure....
Industrial applications, the insurance industry, legal professionals, the courts and more rely on computer forensics for many functions, ranging from preventing the spread of illegal materials to avoiding corporate fraud. Computer forensics is a growing field, and one that will continue to provide evidence and insight to prevent growing criminal computer related activity.

Computers, being vulnerable due to having both wired and wireless connections, have been a victim to internet security threats. However, you can improve your internet and network security by making use of few steps and establish a network that cannot be hacked by anyone.
We can see great efforts being done by many companies to improve their internet and network security. This has been happening because of the progress of high speed internet service and wireless internet connectivity that has attracted many hackers to access it and misuse it. That is why, one can find many vulnerable computers all over the world, being attacked by spyware, virus and malware causing various instances of security issues, identity theft and cyber crimes.
The first step you must take to improve your internet and network is by installing a firewall. A firewall detects any unauthorized communication that tries to take place in a network or any unauthorized communication to access the internet. Firewall can give users options to allow or deny any communication that may appear to be dangerous to the computer.
Spyware are malicious programs that steal highly sensitive data such as usernames, passwords, personal and banking information. Viruses are computer programs that have the ability to multiply and cause severe damage to the computer's performance. Hence, it is also very important to install an antivirus and antispyware in addition to that firewall on your computer. Make sure your antivirus, antispyware and firewall programs are updated regularly.
It is very important to make use of high quality passwords that cannot be cracked by any hacker. Do not download any data or software from any not to be trusted websites. Do not download email attachments if you are unsure about its source. If you think your PC is infected by a spyware, you must checkout the genuinely of any website login page before you submit your username and password on it. You may install additional software that can fix errors in your computer's registry. These are some of the simple ways you can make use of to improve your internet or network security.

It seems that the security risk to federal cyber security introduced by a new or emerging technology is inversely proportional to the convenience it offers to industry. Every few years a hot capability comes along that instantly has businesses clamoring to adopt it, while security professionals scramble to discover and address its vulnerabilities. Wireless networking fell into this category, and the rise of Cloud computing over the last few years appears to be just the leading edge in a massive migration towards virtualization and out-sourced data hosting.
An industry unfortunately lacking standardization and oversight, where the uninformed essentially gamble one of their most valuable assets on a table marked with confusing, and sometimes risky, bets. The "valuable asset" in this analogy is, of course, proprietary data. Businesses, and even governments, frequently fail to comprehend the true value their data and intellectual property represent to their organization-much less the value that information might have to others: "Value" cannot always be measured in monetary terms, and oftentimes the value of an object comes not in its positive potential, but in the negative consequences it might produce in the hands of a competitor, criminal, or wary public.
The attraction to the Cloud is undeniable. Cost savings are frequently realized through the outsourcing of infrastructure, software, technical support, and security controls-assuming those services are effective and reliable. In fact, a service provider may be able to offer a computing capability far beyond what many companies might otherwise be able to afford: An outsourced solution is easily scalable, providing a partial or total solution with ready-made growth capability, and it may also offer increased accessibility to data if that is desirable. With respect to security, for a small or mid-sized company with marginal security to begin with, even a service provider with only modest security features may offer an improvement over the existing system.
When deciding whether or not to outsource it is important for an organization to fully understand and quantify their risk in utilizing the Cloud, starting with a comprehensive assessment of the true value of the data and intellectual property being entrusted to a potential service provider. In an outsourced solution, an organization is relinquishing direct control of their data, and possibly business processes as well, to an entity for which the element of trust may be unknown or at least undeveloped. Significant effort should be expended in understanding the details of the service being provided and defining the level of trust obligated by the contractual relationship. Be wary of Service Level Agreements (SLA) containing contractual elements granting the provider wide latitude and limited liability for the storage or confidentiality of data: For instance, some SLAs include provisions for sharing data with third parties or rights for marketing.
Key information to collect and consider when comparing service providers will include:
• Governance, Oversight, and Liability: When was the service provider's last assessment, and have they had citations or security breaches in the past? Is the service provider compliant with applicable regulatory requirements in handling your data? Are you in compliance with applicable regulatory requirements in outsourcing your data? What is the provider's liability and obligation in case of data loss or compromise?
• Physical and Logical Geography: Where are the data centers physically located that will be hosting your information, and how will your data be partitioned on the server(s) relative to other data stored by the provider?
• Security Controls: How is your data secured, both in transit and in storage? How, when, and where is your data replicated, and how long is it retained? How will various security measures impact advertised access and performance characteristics for the service?
• Physical and Logical Access: What security policies are in place for access to, and modification of, the data center and your data? Who will have access to your data? Possibilities include service-provider employees or administrators, third-party vendors, contractors, as well as officials from governmental, compliance, or oversight bodies.
• Balance Risk versus Trust: Evaluate the costs and consequences in the event your data were lost or compromised, and consider maintaining internal control or heightened security measures for that portion of information critical to the organization or the conduct of business. Such sensitive data might concern proprietary products or processes, intellectual property, privacy information regarding employees or customers, or company financial's.
Although various initiatives are underway for establishing uniform standards and oversight bodies for the virtual sector, many such efforts have failed in the past and effective legal and industry standards for Cloud computing appear to be years away from realization. As tighter security and control requirements do come into play in the industry, it will be interesting to see whether outsourcing remains a cost-efficient and attractive proposition for businesses when weighed against the relative risks.

Computer security is a broad spectrum, and citing the emerging Internet threats it has become a must to do review work. As more and more digital information is getting online through e-mail client, instant messenger, social network, photo sharing websites, etc., your system is more vulnerable and can be an easy target of fraudsters and scammers. Along the installation of Windows, Microsoft Office, browser, e-mail clients, and more, the most essential job is to give your PC the protection of compatible antivirus or Internet security software. Sometimes, despite all protection the system acquires the infection. And, you may be perplexed with symptoms like slow performance, Windows Lockup, system crash, hard-drive failure, disk or drive inaccessibility, and more. At times, there can be silent errors, and before you awake it can be too late.
Avast is renowned brand while you are discussing the computer security aspect. There are home and business products both, and are powered with advanced antivirus and anti-spyware engines to check viruses, spyware, and other malicious agents.

So, before you install avast on your system affirm all requirement. Trace out and remove if there is any outdated security software already running on it. Do it either through Windows Control Panel or using an uninstaller tool as per your convenience. Uninstaller tool should be used with acute precision as it might delete important files or registry settings if taken for granted. Post installation problems related to e-mail send/receive, Internet access, sharing of files and peripherals, etc., can also be there, especially due to wrong settings and lack of update. Most of the times, you can fix the problem on your own, by updating or configuring the software application. Windows Firewall and Windows Update are other main supplementary aspects contributing in the PC performance, and must be reviewed regularly. You can uninstall avast and restore it back as well, if you are not satisfied with its performance.
No matter, you have done all to secure your data, but bad situations are enviable, and can slip anytime. So, you must follow safety measures. Regularly backup your data, and use encrypted system to encrypt sensitive files and folders. Download internet files from trusted sources only and stay away from rogue security software. Use password encryption to protect Office files.
