Now that you're off and running with your ethical hacking tests, it's time to take things to a new level. The tests in the previous part — at least the social engineering and physical security tests — start at a high level and are not that technical. Times, they are a-changin?! You now need to look at network security. This is where things start getting more involved.

This part starts out by looking at the network from the inside and the outside for everything from perimeter security holes to network device exploits to DoS vulnerabilities and more. This part then looks at how to assess the security of wireless LANs that introduce some serious security vulnerabilities into networks these days.
