Are you a networking guy? Do you want to brush your networking skills?
Network security is the practice of preventing and protecting against unauthorized intrusion into corporate networks. As a philosophy, it complements endpoint security, which focuses on individual devices; network security instead focuses on how those devices interact, and on the connective tissue between them.
According to the SANS institute Network security is the process of taking physical and software preventative measures to protect the underlying networking infrastructure from unauthorized access, misuse, malfunction, modification, destruction, or improper disclosure, thereby creating a secure platform for computers, users, and programs to perform their permitted critical functions within a secure environment.
A brief network security consists of Three layers, Protection, Detection, and Reaction. This is a kind of defense-in-depth strategy. But a system should not rely on a single line of the defense system, rather it should have multiple defense strategies lined up.
