Web Browser Security

Today’s attacks have moved to the web – and with good reason. It’s easy enough for attackers to anonymously host malicious files, they have more control and are better able to update those files at will, and (whether through social engineering or compromise of a legitimate site), it’s easy enough for attackers to force those malicious files onto users. There’s a common misconception that switching browsers is all one needs to do to ensure web security and thwart off these attacks. It’s not. Whether you use Firefox, Opera, or Internet Explorer, there are specific steps you must take in each to fend off web-based attacks
Today’s attackers are more likely to host their malicious files on the web. They may even update those file(s) constantly, using automated tools that repackage the binary in an attempt to bypass signature-based scanners.

Attackers may entice users into visiting the malicious site via cleverly worded email, such as greeting card scams. Or they may compromise a legitimate site, outfitting the compromised site with hidden iframes that push exploits and malicious files from the attacker-owned site – with all of this invisible to the casual observer.

Whether through social engineering or through web site exploit, the choice of browser will be of little help. All browsers are equally susceptible to web-based malware and this includes Firefox, Opera, and the much maligned Internet Explorer.
