The defense in depth principle states that organizations should use multiple, overlapping security controls to achieve the same control objective. This is a layered approach to security and protects against the failure of any single security control. If one control fails, there is still another control designed to achieve the same objective standing in its place. Learn the importance of a layered approach to security and how to build a defense in depth strategy.

When designing a secure network,…you should definitely follow…this Defense in Depth principle.…Let's take a look at how we can apply…the Defense in Depth layered security approach…to three different network security control objectives.…First, all network security professionals…want to protect against eavesdropping attacks.…Unauthorized individuals should never have access…to confidential communications.…How might we implement this?…Encryption is always a strong first defense…against eavesdropping attacks.…
