Microsoft took the initiative and created the Windows Server Update Services that allows enterprises to patch their Microsoft products, but other vendors' products are left in the cold. It seems like someone would have approached Microsoft or some highly motivated Microsoft engineer would have said, "Hey, we should open this up for others to use."
But that hasn't happened, or maybe it has and the idea was shot down. That's why vendors like Lumension, BigFix, and others sell enterprise patch management solutions designed to patch multiple operating systems and software from Microsoft, Adobe, Sun Java, etc.
Now you might be thinking patch management sounds great, but it doesn't protect against zero-day attacks like the current one against Adobe Acrobat (see this great video on exploiting the zero-day vuln with Metasploit). Yes, that is true, which is why I would complement patching with application whitelisting so you can control which applications are run on the endpoints in your enterprise.
When looking into application whitelisting, make sure the solution you choose or your antivirus product (or host intrusion prevention solution) has the protections to detect and prevent memory corruption exploits and dll injection. If not, then a whitelisted application could be running, get exploited, and continue to run but with malicious code injected into it while the whitelisting solution is none the wiser.
While not a protection against a lot of social engineering and authorized insider attacks, the two solutions combined would certainly eliminate the majority of them. I wonder if Santa's going to come through this year and deliver some solid enterprise protection.
