Penetration Testing Literature

i'm a student of Applied Computer Science and currently preparing for a student research project on "Systematic Penetration Testing".
Right now i'm searching for literature.

Currently i plan to read the following books:

- Marc Ruef - Die Kunst des Penetration Testing
- Thomas Wilhelm - Professional Penetration Testing: Creating and Operating a Formal Hacking Lab
- Peter B. Kraft - Network Hacking: Professionelle Angriffs- und Verteidigungstechniken
- Chris Hurley - Penetration Tester's Open Source Toolkit, Second Edition

What do you think? What books would you recommend to read?

Best Regards
