Answer 4

A certain percentage of people can be reliably expected to do something resulting in compromise. Why? Research says...they really "just don't care"...no matter how much you train them, etc. Due to this, you want redundant security measures* -- the term is "Defense In Depth".

* Recommended lists of steps can be read by the bad guys too.

Answer 12

@Setiawan Next : I know why Linux is a favorite, and then...Shellshock*

...which gave me time to watch as it took much of the *nix / OSX world by complete surprise.

* and this is not the only one, so I'm just saying...be careful with complacency.
