Systems Maintenance

I mentioned yesterday about the importance of maintaining your systems. Things like keeping your AV, HIPS, OS Patches, software, etc... up to date. If they are left alone in time either a vulnerability will be found in them or someone will break them.

It's also important for companies to realize that just because something is old and now widely know anymore doesn't mean that they can ignore it. Here is a perfect example. A 13 year old boot sector virus was shipped on MS Vista laptops with AV installed on it. The virus got past all of Vista's protections and the AV scanner missed it. I don't know the details, but it sounds like it's a case of the forgotten virus coming back to bite you in the boot sector. :)
