Needless-to-say, having multiple, diverse layers of security is a good idea. It helps protect your network and systems, in the event that there is a failure in one of the layers. The diversity of the layers is also important, as you are only as strong “as your weakest link.” If you have multiple layers of the same type of security, a single bug or breach may bypass all of them at once. This Linux security publication will introduce you to the key concepts Linux system administrators need to understand and teach you best practices to keep your environment safe.
