Cyber security Tips

The vast network of cyber-space presents - or, can harbor -- major threats to the security of personal computers; LAN and WAN networks; and wireless Internet networks. Trained computer networking specialists who are experts in cyber-security are needed to secure networks and computer systems for effective data storage and retrieval. Just as importantly, they are needed to secure the privacy and integrity of personal and corporate identities. These professionals can find work in private firms, in consulting, or at the state and federal government levels. Most individuals complete at least a bachelor's degree before working in the cyber-security field.

Hackers pose special threats to computer network security. These technology and networking experts use their insider information to grant themselves access to computer networks, without permission. Our modern computing environment is an open one, and individuals with systems and software knowledge - or, even, persons with the gumption to steal data or computing devices - can easily get their hands on very sensitive information.

Much information should be kept private, and serious damage can ensue if this information falls into the hands of hackers. One of the greatest risks to business computer and personal computer users who are working on unsecured networks is identity theft. A cyber-thief can use a personal or company address; financial and credit card information; or even a personal social security number to steal money from individual or corporate accounts. This is a serious crime - one with far-reaching consequences, including ruined credit records -- and increasingly easy to commit in today's open-computing, technology-heavy environment. Cyber-security professionals who are adept at designing secure, hack-proof information systems and networks are needed to win the fight against identity theft.

Spyware and viruses pose another threat to the integrity and security of computer data. Spyware is installed on a computer without the user knowing, and can collect personal data or interfere with computer applications or run-time. Viruses are computer programs that replicate themselves to infect the machines, often damaging files or even hard drives in the process. There now exist several types of anti-virus and anti-spyware software that can be installed on a personal computer or on networked office computers for low or no cost. Security professionals on IT repair teams might be trained in the use of this software. Some professionals might provide security consulting services to businesses and individuals, as well.

Skilled cyber-security professionals also know how to install and maintain firewalls. These pieces of software or computer appliances are security devices that monitor activity between networks - usually, networks with different levels of security and access. Firewalls might restrict permissions to various Internet activities or Web sites. The level of security firewalls provide on large business networks can be changed or altered by security administrators. There exist many types of firewalls, including network layers and proxy servers. Understanding what each type of firewall does, and when it should be applied are main responsibilities of a cyber-security student; typically, he or she will take several classes about firewalls to complete a network security degree.

Design and evaluation of secure computer network systems are special skills, in which cyber-security information systems professionals must be proficient. Secure network architecture is imperative in preventing hacking and threats to information integrity. Some cyber security professionals will be employed as business consultants, routinely evaluating system security software, and creating and testing secure network systems.

Finally, some cyber-security professionals might be employed to work on major projects and contracts where information privacy and integrity is vital. The U.S. Department of Defense or the Office of Management and Budget (OMB) in Washington, D.C., for example, need cyber-security specialists to create networks that will protect highly sensitive or classified data. Similarly, cyber-security specialists are needed in biology and scientific research centers, such as those found in universities and hospitals, to make sure data and findings remain secure. Specific federal regulations outline how these findings should be secured, so specialists can help these research centers stay compliant.

The field of cyber-security is a constantly evolving and important area of information systems science. Individuals pursuing an education in this challenging and lucrative field will be sure to find fascinating work and a lifetime of learning throughout their careers.

Security researchers have alerted customers on a new spam e-mail, which attempts to scare users by asking them to make payment of overdue credit card bill. The spam e-mail identified by researchers at Sophos comes with different subject lines and seeks payment of the credit card bill within two days. The scam e-mail warns users that non-payment of the bill within two days may result in late fees and finance charges. The e-mails contain credit card details such as card number and card limit. The e-mail urges users to open the attached .zip file to view bill details.

Scammers attempt to create panic by claiming that their credit card bill is overdue by one week. Users who download the file out of panic or curiosity to check the authenticity of the claim, inadvertently download a malware on their computer systems. Security researchers at Sophos have detected the malware as Troj/Invo-Zip. The Trojan arrives in a Zip file and attempts to download more malware into the compromised machine. The malware affects Windows operating system.

Scammers also attempt to defraud users by sending URLs or image and video files related to an event or celebrity. Scammers may also send a fake invoice related to a parcel service or entice users to fill a malicious form for tax refund. In one of the recent spam attack, scammers attempted to capitalize the death of pop singer Amy Winehouse to download malware and compromise computer systems.

Internet users must not click on suspicious links and avoid downloading attachments in e-mails with suspicious claims. They must regularly update the security software to benefit from the latest virus and malware definitions added by the vendor. They may keep track of the security updates by visiting the websites of Computer Emergency Response Teams (CERTs) and product developers. E-learning and online degree programs may help Internet users in gaining insights on security threats and safe online computing practices.

Scammers may also target employees through social engineering techniques. As such, organizations must update employees on the latest threats through training sessions and e-alerts. They may also encourage employees to undertake online university degree programs to gain understanding of the security fundamentals and improve their cyber security practices.

Professionals qualified in masters of security science help organizations in making assessment of different threats in the IT environment and initiate corrective measures.
