I am a sophomore, want to be in the future Internet police, or in some network security work in the company, so need to learn the network security,

But don't know what the course of learning should now, I have a small base, computer network is probably can just through the network engineer examination level, understanding of network security is limited to network engineers involved in the exam, also I now has a certain basis for c # and Java, are now learning c # network programming and Java network programming, learning network programming will learn asp.net and Java web, Android platform development also to have certain basis at the same time,


I now want to master, in network security can best graduated two years later when the Internet police, when not on the Internet police can into some network security work in the company, and find some books to see, but the feeling is slightly theory, and practical application is a bit gap,

Himself to some of the basic concept of network security have cognitive (in short is involved within the network engineer exam outline is known), and hope you recommend recommend the next learning route and good books,
