What would happen if Mozilla's Firefox suddenly became the browser that everyone was running? What would happen if it was as big a target for hackers and for virus and spyware authors as Internet Explorer is now. How would Firefox's reputation for security hold up? One has to wonder how secure a default Firefox installation is, and if there are things that can be done to make a Firefox deployment more secure?
IE is the bigger target
Firefox has long had a reputation for being more secure than Internet Explorer, but I wondered if that was more perception than reality. I will admit that Internet Explorer (you pick the version) is chock full of security holes if left unpatched. If you look at the types of patches that Microsoft has released for Internet Explorer over the last year though, you will notice that the majority of them address unchecked buffers and other relatively obscure vulnerabilities. It's just my opinion, but I think that the only reason Microsoft even has to worry about patching these types of vulnerabilities is because Internet Explorer is so popular and because it is a huge target for those with malicious intent.
There is very little doubt in my mind that if Firefox were suddenly to become as widely used as Internet Explorer and all of the world's hackers started going after Firefox instead of Internet Explorer, that similar obscure vulnerabilities would start to show up in Firefox just as they did in Internet Explorer.
