CompTIA Security+ Made Easy


Cyber Security has been written about a bunch recently. As computers gain complexity, so do the malicious attacks used to beat the security systems built to guard those systems.

Why Get Certified?

Government employees working in the Information Technology and Computer Security fields, are being expected to complete the Security+ exam in order to stay compliant with the DoD 8570 policy. Several non-government companies are also requesting their employees to receive certification as part of their yearly training plan. Industry standard certifications are a great way to make your resume shine. Professionals seeking employment opportunities as a Security Specialist, Network Administrator, or Network Technician may benefit from obtaining a Security+ certification. Getting Security+ certified can also be worth while for individuals who are already employed and hope to advance their earning potential. The knowledge gained from preparing for and taking the exam is a good justification for seeking the Security+ certification.

About the Exam

The exam contains 100 questions which need to be answered in 90 minutes or less. A score of 750 or higher on a scale of 100-900 must be obtained to pass. CompTIA recommends that you have former network and security experience, but it is not mandatory. The exam codes for the current test are SY0-201 and JK0-015. The current pricing for 2011 in the United States is $266 for non-members and $226 for member organizations.

Exam Objectives

The core objectives for the exam range from broad organizational topics to specifics about various cryptography algorithms. Here's the topic breakdown:

Systems Security - 21%

Network Infrastructure - 20%

Access Control - 17%

Assessments and Audits - 15%

Cryptography - 15%

Organizational Security - 12%

It's easy to feel overwhelmed at first by reading the exam objectives, but don't sweat it. Keep in mind that this exam does not demand a degree in Computer Science and with a good study plan you too can have a good outcome. I'll give you some tips on how to increase your chances for passing the exam on your first try later in this article. I passed the exam on my first attempt with a score of 855 out of 900 and you can too!

Where to Take the Exam?

Pearson VUE or Prometric exam facilities both offer the Security+ exam. If you're a government employee you should receive an exam voucher from your command to pay for the exam cost. You will need to visit the Pearson or Prometric website to schedule your exam date once you are ready to take the exam. Don't be overly anxious to schedule the exam! Be sure you are ready to take the test before scheduling.

Preparing for Success

I did self-paced study for the Security+ exam for 2 weeks and passed on my first attempt with a score of 855 out of 900. My primary job responsibility is not as a Network Administrator or a Security Specialist, so my applicable work experience was minimal. I have some book recommendations and a study strategy that will maximize your chance for success on the first attempt. I highly suggest that you obtain a copy of CompTIA Security+ Deluxe Study Guide: SY0-201 and CompTIA Security+ Review Guide: SY0-201. Begin by reading the study guide cover to cover, making sure to complete the end of chapter practice exams. Then read the review guide cover to cover, making sure to take all of the practice exams too. Both books come with a CD full of practices questions and mock exams. When you can consistently pass the end of chapter practice exams and the mock exams on the CDs with a score of 80% or higher, then you should be ready for the real exam. Take your time, grasp the knowledge, and most importantly have fun!

Exam Day

Here are some closing recommendations that may help make your exam experience go smoother. Review the chapter summaries of CompTIA Security+ Deluxe Study Guide: SY0-201 and CompTIA Security+ Review Guide: SY0-201. Show up early at the exam center so you don't feel as anxious or rushed. Leave your cell phone and other personal items at home or in another secure location since you will be asked to empty your pockets prior to starting the exam. The test administrator will give you a small whiteboard and a marker for note taking during the exam. Don't speak with anyone in the exam facility once you have been seated and begin the exam. While taking the exam make sure to mark any questions you are unsure of and return to them later so you can maintain an unbroken pace of answering questions.

Strong Password Authentication Essential to Your Computer Security


1. Why Password?

 

Your computer and the websites you frequently visit contain a great deal of personal information about you. It is important, therefore to ensure that you do not allow your personal details to get into the wrong hands.

We do so much online these days: banking, shopping and social networking have become everyday activities. There are nasty people out there who want to steal from you. Not just your money, but your very identity. It is therefore very necessary to protect yourself by restricting access to your personal data. This is where passwords come in. They make sure that your personal details are only available to you.

 

2. Why a Strong Password?

 

We all like to keep things simple. Passwords can be a pain. So let us make it easy to remember and  not complicate matters. Why not use the same password for all our safe sites. It is too much hassle remembering all those different passwords, after all.

 

Passwords can be seen as the weakest link between your data and those who could most benefit from access to your personal details.  Once the password is cracked they are in. If you use the same password for different applications, your system is vulnerable, along with your online banking and credit card accounts.

 

Examples of weak passwords include your name, username, date of birth, names of your children, even your car registration number. Paul123 would not be a safeguard against my online bank account, for example. Hackers can use programs that try to guess your password by browsing through your files to search for personal information.

Criminals use a number of methods to identify passwords. Dictionary search trawls through online dictionaries to come up with a match to your password. Brute force attacks try every possible combination of keystrokes that can be used in connection with a user name. Phishing, official looking emails purportedly from banks, for example, seek to obtain passwords or PIN numbers from unsuspecting victims.  

 

3. What is a Strong Password?

 

Many websites demand passwords that exceed seven or eight digits, including letters and numbers. Security experts advise even longer passwords, 14 characters are considered sensible. Experts also suggest that you mix upper and lower case letters and utilise characters in lieu of some letters. The key is to use a password that is simple enough for you to remember but no one else, even your close family and friends would be able to identify.

 

4. Further assistance

 

Microsoft has a very good application that rates the strength or weakness of your chosen password.

Computer Monitoring Tools - How Intrusive Are They?


Computer monitoring tools are used to keep tabs on what's being done on any specific computer or network of connected computers. Business people often use these to monitor employee activities to see whether they are actually earning their pay by working, or spending hours on internet casinos and instant messaging friends for hours on end... or worse, embezzling funds and stealing client accounts. Parents use these too, so that they can protect their children from sexual predators and keep an eye on their children's activities online to see that they don't get into anything pornographic. But how intrusive are these programs?

They're not very intrusive at all, if you ask me. You see, these can be run invisibly and silently, automatically running and recording activities right from the startup of the computer. There doesn't even need to be any evidence that the software exists on the PC. All activities, keystrokes, pages visited, clicks of the mouse, instant messages and such are all recorded onto secret log files which are then stealthily e-mailed to you in secret for your leisurely perusal.

This is also a boon to those who suspect their spouses or relationship partners of cheating, but lack the power of solid, concrete proof. Using computer monitoring tools for these purposes, you can be sure that everything can be done with absolute secrecy, you can protect yourself and your children, and even protect your business and your clients' delicate private and financial information. It's all about safety, security, and just good common sense. Don't you agree?

Virtual Private Network Frequently Asked Questions


1. Why do I get disconnected after 4 hours of use?

(a) You will get disconnected because of the limited number of ports and the fact that 90% of all users do not need to be connected more than 4 hours, all units have been set to a 4-hour time limit.

(b) If you require more time, you should disconnect gracefully before the time limit and reconnect so that you do not lose your work.

2. Why not use an 800 number all the time?

(a) Using an 800 number costs the corporation 5 cents a minute versus calling a local number when available that costs 5 to 7 cents one time charge to initiate the call with no per minute charges.

3. Do I have to be connected when Email comes in or to prepare Email?

(a) No, Email is stored in your server until you need to access it.

(b) The proper way to handle Email when working remotely is to make a connection periodically during the day pulling your mail down and then disconnecting.

(c) You can prepare your Email in the offline mode.

(d) When you make your next connection to process incoming mail all prepared mail can be sent at this time.

4. What about reconnection issues?

(a) If you are running Windows 95, NT, 2000 or XP making re-connections should be as simple as clicking on the icon to reconnect.

5. How do I speed up my dial-in connection?

(a) Only install the necessary protocols.

(b) Usually IP is the only one needed unless you are accessing Novell Servers.

(c) Never install NetBEUI.

(d) A good practice, if only accessing Novell Servers occasionally, is to create two configurations, one with IP access only and one with both IP and IPX. Use the second configuration only when required.

6. Why can't I see all of the NT units in the Network Neighborhood?

(a) When you dial into the Network Access Gateway you are normally on a segment without a master browser, which is how units are displayed in the Network Neighborhood.

(b) This does not mean that you cannot access the unit however.

(c) If the unit you are trying to access is a member of the corporate WINS structure and you have configured your remote unit per the configuration instructions, WINS will automatically resolve the units IP address when you Map a drive in Explorer.

(d) The key to this is to know the computer name and share name that you require before starting the process.

7. Why does my Dial-Up Networking fail to work after loading AOL?

(a) AOL sometimes replaces the TCP/IP Winsock driver, causing your PC perform erratically or not at all.

Fix:

1. Delete all references to TCP/IP from the network neighborhood properties.

2. Reboot the system.

3. Add the Microsoft TCP/IP protocol back in.

This will automatically add TCP/IP to all adapters and you should be functional again.

8. Can I use Network Address Translation (NAT) to attach my home computers via VPN?

(a) In general NAT is not supported by the IPSEC VPN client.

(b) Routers such as the Linksys BEFSR11 and BEFSR41 do support VPN with a software workaround.

(c) NAT implementations may be used if One-to-One NAT is used.

9. Why can't I get higher speed on my 56K v.90 modem into some NAG sites?

(a) A 56k v.90 modem is asymmetric by design, so download speed can be as much as 56k but upload speed will be only up to 33.6bps.

(b) For 56k to work, there must be only one analogue to digital (A/D) conversion in your local phone loop.

(c) Thus when modems at both ends are analogue, 56k speeds will never be achieved as most PSTN exchanges run digital routing.

(d) Some NAG sites use analogue phone lines with Cisco and standard 56k modems, while most PCs dialing up use a similar modem.

(e) Between both the modems, it limits the download speed to about 33.6kbps maximum.

(f) At the same time, many users might experience lower connection speeds due to other reasons, such as more poor line quality.

(g) These factors will also contribute to the quality and speed of the line.

10. When I load the Extranet Client on my PC and Winpoet is installed on my machine, it crashes or does not work properly.

(a) There are known issues running Winpoet software on the PC with the Nortel Extranet (VPN) Client.

(b) To repair your system, boot in safe mode and uninstall the Winpoet Software.

(c) A simple solution is to have users install the Linksys BEFSR41 hardware router.

(d) It has a firmware PPPOE connector, which eliminates Winpoet from the PC and provides the added benefit a NAT firewall for the user with the ability to hook up to three other PCs.

(e) A second option is to find a PPPOE Client that does not interfere with VPN Clients.

(f) If you have WINPOET, please check with your local ISP to confirm it will work with the Nortel VPN client.

(g) If not, or if they are not sure, please do not install the new client, or ask your ISP to find an alternative PPPOE Client that does not interfere with the Nortel VPN Client.

(h) If you decide to use Winpoet with the new Nortel VPN client, Nortel strongly recommends using Winpoet 6.0 or higher.

(i) Earlier versions of the Winpoet software are known to cause conflicts with the Nortel VPN client.

(j) If you have Winpoet on your PC and experience problems (i.e. with an earlier version prior to 6.0) the following 8 steps will safely uninstall the Winpoet Software from your pc and repair your system to boot properly.

1. Login to Safe Mode.

2. Login under Admin profile.

3. Go to Add/Remove programs and uninstall Extranet Client. Do NOT reboot at the prompt.

4. Check to see if Winpoet adapter is installed. If so remove it.

5. Go to device manager/network adapters. Right click Winpoet or Winport adapter. Uninstall.

6. Go to Admin Tools./Services and disable Winpoet-over-ethernet.

7. Reboot PC.

8. Reinstall the extranet VPN client.

An alternative solution is to install the Linksys BEFSR41 hardware router. It has a firmware PPPOE connector, which eliminates the need of Winpoet from the PC.

11. My ISP remains connected and I have no known problem with my Internet Service Provider. The problem is intermittent.

(a) Check the version of your Contivity Extranet Access client.

(b) You should be using the current release of the client, 4.65 or higher. You can view the most current version by clicking on Current Version.

12. I am having problems with my VPN connection.

(a) Try isolating the problem by process of elimination.

1. Is your Internet connection to the public Internet working properly?

2. Do you have the most current version of the Contivity Extranet Access client?

3. Have you recently installed any new software or hardware?

4. Were any hardware or software changes made since your VPN connection was last working?

5. Have you scanned your computer for Viruses?

(b) If you are still experiencing problems, try uninstalling or removing the following items.

1. Disable your firewall, anti-virus software and any other maintenance or Security programs installed.

Try to connect.

2. Remove your router from your configuration.

Connect your PC directly to your Internet connection.

This is accomplished by connecting the cable coming out of your DSL/Cable modem, directly into your network card or USB connector.

If successful, the problem might be your router's setup or firmware.

Refer to your Manufacturer's website or documentation for troubleshooting your router or contact the Vendor directly for support. Cheat Note: Caution: use this idea at your own risk - usually there is a little hole in the back of the Router and you can stick a round toothpick into it and push the button inside and it will reset the Router to the Manufacturers settings, do this while the Router is unplugged from any electrical source. This should not upset any of your configurations but do not break the toothpick off inside. It may be best to use a bobby-pin.

You must upgrade your firmware.

Please beware even though you might have just recently purchased your router, it might have been packaged with an older version of the software.

3. Enable your router, firewall/internet security programs one at a time.

Cable/DSL users: If you have a dial-up modem installed on your PC, try to test using a dialup connection.

Either use dialup to an ISP and then use VPN or dialup directly into your Network.

13. The upgrade to release 4.6X of the VPN client failed.

(a) Refer to the list below and see if any of this applies:

Windows XP Disable the XP firewall.

VPN Software Most VPN clients cannot co-exist on the same machine.

Windows ME Remove and Add TCP/IP protocol.

Brother Multifunction Printer You may not be running the current Brother software for your printer.

Windows 2000. Users should download drivers/software from the Brother website.

14. How can I remove and re-install TCP/IP Protocol?

Below are instructions on how to remove and add TCP/IP for Windows 2000. (Refer to your operating system's help screens, web support and/or documentation for instructions, if you are not using Windows 2000.)

(a) Please be sure, no matter which operating system you use, that you elect to restart when finished (as prompted) or restart between each process.

(b) For Windows 2000 you must be logged on as an administrator or a member of the Administrators group in order to complete this procedure.

(c) Remove TCP/IP

1. Open Network and Dial-up Connections, click Start, point to Settings, and then click Network and Dial-up Connections.

2. Right-click any network connection, and then click Properties.

3. On the General tab (for a local area connection) or the Networking tab (all other connections), click Internet Protocol (TCP/IP), and then click Uninstall.

4. In the Uninstall Internet Protocol (TCP/IP) dialog box, click Yes.

(d) Install TCP/IP

1. Open Network and Dial-up Connections. (Click Start, point to Settings, and then click Network and Dial-up Connections.)

2. Right-click the network connection for which you want to install and enable TCP/IP, and then click Properties.

3. On the General tab (for a local area connection) or the Networking tab (all other connections), if Internet Protocol (TCP/IP) is not in the list of installed components, then do the following:

A. Click Install.

B. Click Protocol and then click Add.

C. In the Select Network Protocol dialog box, click Internet Protocol (TCP/IP), and then click OK.

D. Verify that the Internet Protocol (TCP/IP) check box is selected, and then click OK.

TCP/IP is installed as the default network protocol if network adapter hardware was detected during Windows 2000 Setup. You only need to follow these instructions if the TCP/IP default selection was overridden during Setup.

15. I am using Windows XP Home or Professional and am unable to get to certain websites or resource servers when connected using VPN.

(a) There are some known issues when using the Contivity Nortel client 4.60 on a PC running Windows XP.

(b) The older version of the Nortel client (version 3.70) will fix the problem; however, the ultimate goal is to upgrade to the current version.

(c) Please do not reinstall version 3.7X as a fix.

16. My ISP provider requires the installation of WinPoET. Can I use it with the latest release of the client?

(a) If you are using WinPoET, it must be version 6.0 or higher of WinPoET.

(b) Check with your ISP and request v6.0 or higher of WinPoET.

17. After installing v8.0 of AOL, I've experienced problems with my connections to my Network.

(a) Users may experience problems with Windows Outlook email.

(b) You must create two separate profiles; one profile as a Remote Connection (POP3) account for your AOL Internet email and another profile for a local LAN connection to your corporate Network email.

Here's how to do it:

1. Go to Start, Control Panel, Mail, Services, Show Profiles and Add the second profile.

2. Make sure the button "Prompt for a profile to be used" under General tab of MS Outlook properties is selected.

3. Disable the ATWPKT2 driver. (The files ATKPKT2.SYS and ATKPKT2.VXD are located in the AOL directory under PROGRAM_FILESCOMMON_FILES.)

18. I'm Unable to obtain an IP address while "Hotelling".

(a) When working remotely from a Hotel (Hotelling), you must launch your Internet explorer first and try to obtain an IP address.

(b) If you just launch VPN, you won't have obtained an IP address, and VPN may fail.

(c) Disable your firewall, as the hotel may recommend.

19. Why do I get No Domain Available when dialing my ISP?

(a) On your Internet Service Providers (ISP) dial connection, right click the mouse and select the properties button.

(b) Click on the Server Type tab and make sure that the "Log On To Network" box is unchecked, otherwise you will hang trying to log into the Network when trying to connect.

20. Why do I run so slowly when using my VPN connection?

(a) On your Internet Service Providers (ISP) dial connection.

(b) Right click the mouse & select the properties button.

(c) Click on the Server Type tab and make sure that the NetBEUI and IPX/SPX boxes are unchecked; otherwise you will see delays while the system tries the unsupported protocols.

(d) VPN only supports the TCP/IP protocol so checking these boxes will only slow you down.

21. Why can't I access my NT resources when using VPN?

(a)Windows 95 users should make sure that they have the "Log On To the Network Box" checked in the Extranet Client per the instructions for the Extranet Client Install to use NT resources such as Exchange and file shares.

22. Why do I seem to be running slowly through my VPN connection?

(a)Try turning off the Software Compression option on your Internet Service Providers (ISP) dial connection as the VPN client has it's own compression. Right click the mouse & select the properties button.

(b)Click on the Server Type tab and uncheck the "Software Compression" setting.

23. Why can't I get to my Novell Servers when using VPN?

(a)VPN only supports the TCP/IP Protocol & most Novell Servers require that you use IPX/SPX to access them.

(b)Work with your Novell Administrators to change to NT or use a Version of Novell that supports IP traffic.

24. Cannot VPN Web Servers on the Internet after Establishing a Contivity VPN Client Connection.

(a) Cause:

1. This is normal and occurs as a result of having all network traffic passed through the corporate network.

2. Typically, firewalls and other security measures on the corporate network will limit your VPN to the Internet.

(b) Action:

1. The Contivity VPN Switch administrator can set up a default route on the Switch to forward traffic to the Internet.

2. If this default route is not configured, you will need to disconnect the Contivity connection to web browse the Internet through your ISP connection.

25. Cannot VPN Network Shares After establishing a Contivity VPN Connection.

(a) Causes:

1. WINS Server may not be configured for IPsec connections on the Contivity VPN Switch.

2. Your system may be setup for a different domain than the one on the remote network.

(b) Actions:

For the first problem, validate that the Contivity VPN Client has been configured with a WINS Server.

1. Follow the steps outlined above under "Problems with Name Resolution using DNS Services" to run IPCONFIG at a Command Prompt on NT 4.0 and to run WINIPCFG on Windows 95.

2. Verify that a Primary WINS Server is listed under the section for the adapter named IPSecShm on NT 4.0 and on Windows 95.

3. Verify that a Primary WINS Server is listed in WINIPCFG for the Contivity VPN Client adapter.

4. If there is no Primary WINS Server listed, notify the Network Administrator that the Contivity VPN Switch may not be properly configured.

(c) For the second problem, skip the initial domain logon when Windows 95 starts and select "Log on to the Remote Domain" under the Options menu of the Contivity VPN Client dialog box.

1. You will then be prompted to log onto the domain of the remote network after the Contivity VPN connection is made.

2. This is the recommended method for users with Docking Station configurations.

(d) Alternatively on both NT 4.0 and Windows 95, change your workstation to be a member of a Workgroup instead of a Domain.

1. From the Start Menu select Settings then Control Panel.

2. In the Control Panel, double-click on the Icon labeled "Network". The Network Control Panel applet will open. Select the Identification tab.

3. On Windows 95, the entries on the Identification page can be modified directly, while on NT 4.0 it is necessary to click the Change button to change the entries.

4. Change to use a Workgroup and verify that the "Computer name" does not match one that may be on the remote network.

5. The name for the Workgroup is not important, so enter anything. Click OK to save the changes and reboot the machine.

When accessing a resource on the remote Domain, if you are prompted for a username and password, you will need to have a Domain name precede your user ID.

For example, if your user ID is JoeS and you are accessing a machine on the remote Domain named CORP, you would enter your username as CORPJoeS.

26. When trying to load the VPN Client on a Dual Processor unit you get an error message.

(a) The Nortel VPN Client currently does not support Dual Processor units.

27. When I set up my home network, I installed Microsoft Internet Connection Sharing (ICS) so that all of my systems can reach the Internet. Now my VPN client no longer works.

(a) The reason for this is that the Microsoft ICS uses Network Address Translation (NAT) to get the Internet connection, and NAT, which may not support IPSec connections.

(b) The only way around this currently, is to make the unit running the ICS be the one you run your VPN connection from. Any downstream unit will not be functional for VPN.

28. Can Cisco or other IPSEC VPN Client software exist on the same box with Nortel Extranet Access Client? Is this supported?

(a) They cannot coexist, and it is not supported.

(b) The two virtual adapters installed with each client will conflict with each other.

(c) There is a utility on the new Cisco clients that will uninstall a Nortel client if found by the Cisco VPN Unity Client install program.

(d) All other VPN Clients require manual removal of the Nortel client or any other client.

29. I am having problems with my VPN connection not already discussed.

(a) Try isolating the problem by process of elimination.

1. Is your Internet connection to the public Internet working properly?

2. Do you have the most current version of the Contivity Extranet Access client?

3. Have you recently installed any new software or hardware?

4. Were any hardware or software changes made since your VPN connection was last working?

5. Have you scanned your computer for viruses?

(b) If you are still experiencing problems, try uninstalling/removing the following items.

1. Disable your firewall, anti-virus software and any other maintenance or Security programs installed. Try to connect.

2. Remove your router (Linksys, D-link, Cisco, Netgear, etc.) from your configuration.

Connect your PC directly to your Internet connection.

This is accomplished by connecting the cable coming out of your DSL/Cable modem, directly into your network card or USB connector.

If successful, the problem might be your router's setup or firmware.

Refer to your manufacturer's website or documentation for troubleshooting your router or contact the Vendor directly for support.

You must upgrade your firmware.

Please beware even though you might have just recently purchased your router, it might have been packaged with an older version of the software.

3. Enable your router, firewall/internet security programs one at a time.

Cable/DSL users: If you have a dial-up modem installed on your PC, try to test using a dialup connection. Either use dialup to an ISP and then use VPN.

30. VPN Problems with Name Resolution using DNS services.

Cause 1:

A DNS server may not be configured for IPsec connections on the Contivity VPN Switch.

Action 1:

Validate that the Contivity VPN client has been configured with a DNS entry.

For NT 4.0, open a Command Prompt and enter IPCONFIG /ALL.

Verify that a DNS server entry is listed.

For Windows 95, from the Start menu on the taskbar, select Run and enter WINIPCFG.

Select "Contivity VPN Adapter" from the pull down list of Adapters, then click More Info.

Record the information displayed under DNS Server entry and verify it with the network administrator.

Cause 2:

The hostname being resolved has both a public and a private IP address. This is commonly referred to as a Split-Horizon DNS.

Action 2:

Open a Command Prompt and ping the host you are trying to reach with a fully-qualified hostname (for example, [http://www.vpnclient.com]).

If you receive a response, verify that the IP address returned on the first line (for example, www.vpnclient.com [207.78.33.329] is an IP address from the remote corporate network.

If it is not, notify your network administrator that the internal hostname should be modified so that it is not the same as the external hostname.

Cause 3:

The retail release (a.k.a. "release 1") of Windows 95 contained a bug that prevented use of more than one DNS server. This problem was fixed in OS Release2.

Action 3:

If you are using a release of Windows earlier than Release 2 of Windows 95, then you need to upgrade.

31. I am having problems mapping drives using the latest VPN client.

(a) This is a known issue due to Microsoft that can occur when using cached credentials behind a NAT firewall.

(b) The problem will occur for some users, but not others.

(c) It can occur regardless of the VPN client you are using.

(d) Some users may only experience this problem after upgrading to a new VPN client, but restoring the old client does not necessarily fix the problem.

(e)You may try uninstalling the VPN Client and then reinstalling.

By default the last two are checked in the box above but I normally check the top option "Show unsafe/red URLs only" This will just flag the bad links so it doesn't fill your web page full of green check marks. Check out the screen shots the website.

Malwarebytes

Malwarebytes by far is much better than Spybot will ever be. Some people swear by Spybot but I have came to the conclusion that Malwarebytes does a far better and more thorough job. Malwarebytes seems to find things that Spybot can't. Screen shots of Malwarebytes are on the website.

The free version does not have the ability to auto update and schedule a scan. Nor does it have the ability to run in memory. But the cost to enable this functionality and upgrade to the PRO version is worth every penny at 25 bucks with no subscription requirement.

Spywareblaster

Javacool Software's Spywareblaster is one of the most clever and simple products ever designed. It not only works on all the major web browsers but it will prevent you from going to those sites that are infected with spyware. The free version does not have the ability to update automatically but works just fine if you remember to update it at least once per week. But should you desire to purchase the autoupdate feature you can get a yearly subscription for 10 bucks a year. There is a network version of this product as well for a reasonable cost if you use it fore a business. This software product will prevent you from getting most spyware, adware and browser highjacks.

Cloud Computing And How It Can Impact Your Business


Successful business is done by groups, not individuals. It takes an entire team of people to efficiently create, test, and distribute products and services. So why are so many business programs on the computer designed to be only used by one person? Wouldn't it make sense to provide all the workers on a team with an option for real-time collaboration and the ability to access to the same set of resources and tools related to the project they're working on? Cloud computing allows the storage of information on a server that can be accessed by multiple users. There's many benefits to this system of computing. Some of these benefits include improved worker productivity, decreased expenses for users, and the ability to work from any device with Internet access.

Workers can save time using cloud computing therefore increase their productivity. Instead of working on documents and spreadsheets individually and then e-mailing them to coworkers asking for comments and criticisms, members on the cloud can receive real-time input and assistance from their peers who are working in tandem with them on the same file.

Hard drive space is both essential and expensive, and cloud computing can save its users a significant amount of money by freeing up room on users' computers. Large, important documents that once needed to be kept in a folder on a user's personal computer can now be stored on a server, leaving more room for other files that the user may need. There are no downloads required for cloud computing. Simply log into the network and store the desired files.

Since work is stored on a server and not on an individual's computer, project team members can access files on the cloud and work from any computer, phone, or tablet that has Internet access. This allows files to be edited regardless of their location, so if a user remembers they need to make a change to a document but they've already left their computer, it's possible to use another computer or a smartphone to open and edit that document.

Cloud computing can make life easier for business owners and employees. Although there have been skeptics of cloud computing who claim there's a number of security risks associated with the practice, these risks must be very minor or non-existent if companies as big as Amazon, Yahoo, Google, and Microsoft are cloud advocates. Proper safety measures can be taken by strictly limiting who has access to sensitive information, and this will all but eliminate any chance for security issues and allow users to improve work quality.

Public Wi-Fi: The Secure Way


Cafeterias, malls, bars and many other such places offer to its customers free internet access. So most of these customers carrying laptops, smartphones or tablets, use the offered free Wi-Fi network to check their mailboxes, chat, surf, even work online connected to their office's network ignoring the enormous security risks provided.

Just to be informed, Wi-Fi free access networks are usually the favorite place for malicious users, who would try to use all their available tools and techniques in order to obtain confidential data, credentials, files, personal information and anything else they are willing to get from your PC.

We suggest to keep in mind the following 6 practices when connecting to your e-banking account or while writing your genius business plan at the local cafe:

You thing you are secured?

Think of Wi-Fi hot spots as the most unsecured connections. You may find yourself sitting next to a hacker while trying to pay your bills! It is very easy for a malicious user to steal data from your PC even the whole hard-disc.

Be encrypted

More and more sites use HTTPS protocol in order to encrypt the activity of their users. So any actions made on that site are confidential. Always look for a padlock in the address bar, or simply check the URL for HTTPS.

Use the security tools

Nowadays all the operating systems have built-in security features that you should take advantage of, if you are not using other security software. Enable your firewall through security settings and check off "Block all incoming traffic." By enabling this setting you will keep most of the malicious users out of your system. Disabling file sharing is also an important security measure.

Password protection

Malicious users are able to retrieve saved passwords from your Registry or install keyloggers, which make your keyboard activity available to them (including passwords you type in). You could easily install something like LastPass, a browser add-on that stores your passwords in the cloud. By using something like this, you'll never have to type a thing and passwords won't be saved on your computer.

Be aware of the name

Fake network names are very common. Hackers create false networks by using attractive names to lure the victim in. Always ask the employees of the cafeteria to confirm the name of their network.

Be smart

There is only one rule if you cannot remember all of the above. All open networks are dangerous. Of course this is not true but if you thing like this you will be able to avoid serious problems.

So the next time you will use a free Wi-Fi hotspot, you should think about it twice.
