Q. Building a Defense in networking?

When building a defense you must use a layered approach that includes securing

- The network infrastructure the communications protocols,

- Servers,

- Applications that run on the server as well as the file system and

Require a few form of user authentication.

When you configure a strong layered defence an intruder has to break by several layers to reach his or her objective.

- For illustration to compromise a file on a server that is part of your internal network a hacker would have to

Break your network security

Crack the server's security

Crack an application's security and

Crack the local file system's security.
