It is important to review the security of a browser as it is one of the most used tools on a computer. Often the default settings of a newly loaded browser are not configured with safety as a top priority; therefore there are many factors to consider when evaluating the security of a browser.

Some features that make a browser more vulnerable:

  • ActiveX
  • Java
  • Plug Ins
  • Cookies
  • Scripting
  • Pop Up Windows

Threats to a browser:

  • Spyware
  • Viruses
  • Malicious web sites
  • Take over of a computer
  • Phishing

Tips to make a browser more secure:

  • Keep the browser up to date with new releases
  • Use and keep up to date antivirus, antispyware and other security software
  • Employ safe practices when using the web
  • Only activate features of the browser that are absolutely necessary

Some of more popular browsers are Microsoft's Internet Explorer (http://www.microsoft.com/windows/Internet-explorer/default.aspx), Mozilla's Firefox (www.mozilla.com/firefox/), and Apple's Safari (www.apple.com/safari/). Each browser has procedures to modify security settings, so visit the browser’s web site for complete instructions.
