Cyber War and Security

Lessons learned regarding cyber attacks against nation is that the awareness and reality of these attacks are brought to light. We learned that the chinese and Russians attacks the US very often by trying to hack into the pentagon's computer systems or trying to carry out anyform of sabbotages.
These attacks should be treated with all seriousness and actions should also be taken against countries engaged in waging cyber wars against the other.
The countries that are developing the technology and defenses against cyber warfare are US, NATO, Russia, GB and possibly China. I believe cyber attacks are to be likened to Nuclear attacks because the damages that can be caused could be similar.
The Georgian- Russian conflict started in cyber space long before the actual war. We all saw the result, and how the Russian Government (although denied it) crumbled the Georgian governmenct sites and caused lots of Denial of Service attact on their networks.
I am happy that the Obama administration is taking this threat seriously and has appointed cyber security czar to tackle this problem.
