I was wondering what your opinions were on the security of different Internet Explorer versions. Now, I know there are philisophical opinions that other, less profuse browsers, are more secure because fewer people use them and so they are targetted less (the Mac defence), but for this thread, I'd like to concentrate on IE. Also, when I say an older version, I don't mean an unsupported version such as 4 or 5, but the previous versions that are still supported, such as 7 (and 6?) compared to the "current" version 8. The general consensus seems to be that you must always have the "latest", most "up-to-date" version of any software to take advantage of the latest bug fixes and security updates. But IE8 isn't simply a more up-to-date version of IE7, it is a separate browser. IE7 with all the latest patches and security updates, is just as up-to-date as IE8. Maybe, even more so, as IE7 has been around longer, could it have had a higher proportion of it's holes plugged, than IE8? Also, IE8's "extras" and "new features" will introduce potential new vulnerabilities. Essentially, IE8 will have vulnerabilites that IE7 does not (and cannot) have, IE7 has had a couple of extra years of "development" (repairs?) and so should have a greater proportion of vulnerabilities fixed, and, as they are both still currently supported, they will both receive fixes for any newly discovered security flaws. So, is IE7 more secure than IE8? Discuss.
