One of the major security threats that computer users face in the last years are web browser exploits. These exploits use 0-day vulnerabilities to infect web browsers that have not been patched to protect against the vulnerability. It does not always have to be the user’s fault if a web browser has not been patched yet. It can take hours or even days before browser developers are able to release a patch that is protecting the web browsers leaving the browsers vulnerable to attacks in the time between.
Some plugins and add-ons help against these types of exploits and attacks. Notable is for instance the NoScript add-on for the Firefox web browser which disables script unless the user has explicitly given permission. The problem with these exploits on the other hand is that they might appear on trusted websites in the form of manipulated banner advertisement.
F-Secure Exploit Shield could be the solution against most of these attacks and exploits. The security software program, which is currently offered as a beta version for Microsoft’s Internet Explorer and Mozilla Firefox, uses a vulnerability shield and proactive measures to protect computer systems against these forms of attacks,
Vulnerability shields offer patch equivalent protection. They are usually hotfixes created by F-Secure employees that protect against known web browser exploits. The proactive shield on the other hand uses heuristics to identify and block unknown or unidentified web browser exploits.
F-Secure Exploit Shield can be downloaded from the Labs section of the company’s website. It is currently compatible with 32-bit editions of Windows XP, Windows Vista and Windows 7 and protects Mozilla Firefox and Internet Explorer web browsers on these computer systems.
