Sun, 2014-06-29 03:47
Assessing overall security on a new system before it goes on-line is also a good idea. It's useful to find holes before somebody else does, verify secure configurations and testing.  Penetration Testing is the process of attempting to gain access to resources without knowledge of credentials and find security weaknesses (Interesting paper).
Penetration Testing A Hands-On Introduction to Hacking By Georgia Weidman. A book was written about the basic of Penetration testing. It gave concepts, ideas, and techniques in 5 parts: The Basics, Assessments, Attacks, Exploit Development and Mobile Hacking.
  • Crack passwords and wireless network keys with brute-forcing and wordlists
  • Test web applications for vulnerabilities
  • Use the Metasploit Framework to launch exploits and write your own Metasploit modules
  • Automate social-engineering attacks
  • Bypass antivirus software
  • Turn access to one machine into total control of the enterprise in the post exploitation phase
First of all, Readers must set up their Virtual lab by using Kali linux. A book gave lots of ideas, examples how to use Tools for Penetration Testing. It's very good book for some people who are new with Penetration Testing. It might not cover everything about Penetration Testing, or gave the deeply knowledge. However, it helps readers are able to understand in Penetration testing easily and practice in examples.
