Internet security

Introduction to network security

Enormous boom of internet expansion led to complex and highly automated technology development that is hard to secure. Internet faces a huge variety of threats because it depends on computer software that is vulnerable. Black hat programmers analyze such vulnerabilities and develop malicious software that takes advantage of software bugs to gain access to computers that are connected to the internet.

Damage of such illegal activities varies from simple vandalism that leads to loss of data or denial of a valuable service to sensitive data theft that might lead to loss of privacy and money.

How to protect your computer from spyware and malware

Choose an appropriate web browser - Internet Explorer is known to be very vulnerable, keep it for viewing web pages that you trust; choose a secondary web browser, such as Mozilla Firefox, for viewing web-pages that you don't know.

Use updated software - Make sure that your web browser is not an outdated one. Latest versions usually have most known bugs fixed.

Avoid bad neighborhoods - Try to avoid questionable sites that might have malicious software.

Don't click on popups - Avoid clicking on popups even if they are similar to operating system messages. Computer spyware hides behind “Your computer might be at risk” and similar popups.

Do not install unknown software - Do not agree to messages asking to install of unknown software or plugins.

Install effective antispyware solution - Antispyware software scans the information you are receiving from the internet and alerts if possible threat was detected.
