I am working on some research regarding advanced persistent threats. Within this effort, discussion of cyber-warfare started. Looking further into the subject, I have found a plethora of links regarding the US and China when it comes to state sponsored initiatives when it comes to offensive cyber warfare but virtually nothing regarding other states.
Though I would be more than happy for more information regarding any part of this topic, my question is this... What countries currently have cyber security procedures/policies/organizations which address offensive security measures?
Granted there is a bunch of speculation regarding Russia and North Korea, and some information about Isreal/Iran out there. I am looking for actual state sponsored activities, not just speculation of them.
This is not specifically IT Security practice, but it is very related, so I felt that it was reliant to this StackExchange.
Thank you for any help you can provide.
