What is Defense in Depth?
Defense in Depth is the proposition that multiple layers of security are better than a single protection mechanism. The layers may be technological, procedural, or policy.
Defense In Depth
This paper will look at three common scenarios for network attacks, likely methods of attack, and countermeasures to protect the network from the attacks.
