Time for another Q&A session!

After the last Question / Answer session I had the other week, I've decided to have another one and make it a (semi) regular feature. Thousands upon thousands of you wander through this place daily but it's great to actually see what's on your mind, security-wise.

So...for the second time...post up your questions here, and I will respond to them this coming Friday. It helps if your questions are security-based, but not always a requirement. Just let it rip, and we'll see what we get.
