NAT, Security, and Repeating Myself

In a former post I pointed out that we need to think of obscurity as a tool in network security — that we shouldn’t try to apply rules that are perfectly logical in terms of algorithms to networks as a system. While I’m not normally one to repeat myself, this topic needs a little more […]
