Friendly Reminder: Patch Your Internet Explorer

Microsoft released an out-of-band patch for its Web browser earlier this week.

To keep you on your toes, Microsoft has released its first out-of-band security update of the year. The fix targets that pesky Internet Explorer zero-day issue I discussed in last week's Security Advisor.

Unlike the temporary fix that Microsoft released at the beginning of the month, this security update bulletin looks to actually solve the memory hole that led to active remote code execution attacks online. For those with Internet Explorer 9 or 10, take an extended lunch -- the vulnerability targeted is only found in Internet Explorer 6 (who is still using 6?), 7 and 8.

Just with Microsoft's monthly patch rollout, the update should only be applied after all testing is complete. But don't put it off for later, it's rated "critical," Microsoft's highest severity warning.

My suggestion? If you haven't upgraded to the latest version of Internet Explorer, you might as well do that. Internet Explorer 9 and 10 come packed with some enhanced security features not found on the outdated browser versions.

Firefox and chrome can be as bad as IE if not patched. The best advice is to use whichever browser you get on with and keep it up to date.

My suggestion is to install Firefox and/or Chrome and only use IE when you have to.

There continue to be critical systems in many businesses that cannot work on Windows Vista or Windows 7, and since Microsoft decided not to make versions of IE from IE8 on compatible with Windows XP, there are no upgrade options. Most people who have not upgraded their IE do not have the choice you so blithely mention.
