x.805 -> ISO18028-2
It was recently announced that the x.805 standard became also ISO18028-2. It's a network security standard. It was presented to me by my friend Nelson Correa. It was written by people related to the telecom world, and it's very similar to other telephony standards, with all its planes, dimensions, etc.
Anyway, I think it's a great document. I like it because it's very pragmatic, more focused than, for example, ISO17799. I suggest to any Infosec professional to take a look at that. There is a draft available here.
