Test Center guide to browser security
Chrome, Firefox, Internet Explorer, Opera, and Safari have different security advantages and shortcomings. More important than the browser you choose, however, is how you maintain and use it.Follow @rogeragrimes
Google Chrome 1.0
Chrome has the potential to be one of the most secure Internet browsers, but its initial showing only leaves significant questions. Read the complete review.
Mozilla Firefox 3.12
Mozilla's Firefox deserves the growing market share it has today. It is a battle-tested veteran with best-in-class cipher support, excellent add-on management, and growing enterprise features. Firefox has a fair amount of security granularity and is the only browser besides Internet Explorer to provide multiple security zones, although they are not easy to configure.
Microsoft Internet Explorer 8 beta 2
Internet Explorer is the most frequently attacked browser in the world. Its popularity, complexity, and support of ActiveX controls gives it an elevated risk as compared to the rest of the competition. Still, it also has best-in-class enterprise support, superior security granularity, and multiple security zones in which to deploy Web sites with different trust requirements. It's the only browser with built-in parental controls and a granular add-on manager.
It is also the only browser with serious enterprise management features, providing more than 1,200 customizable settings across multiple security zones. For example, the U.S. government requires what is called FDCC (Federal Desktop Core Configuration) on all of its software, and FIPS (Federal Information Processing Standards) ciphers only. Tens of millions of PCs fall under these requirements. Only IE allows these policies to be enforced across all desktops. It is difficult to achieve with any of the other browsers.
IE 8 is bringing many new features to the table, including per-user and per-site control of ActiveX programs and other add-ons. Its improved base security model is second only to Google's Chrome, and nearly every security feature it has is mature and built for enterprise use. Read the complete review.
