The topic of our term project is developing a port scanner that can successfully evade detection by network defenders. Scanning is large component of the penetration testing cycle, especially when the tester isn't given any prior information about the network with exception of an internet protocol (IP) address rage. In this type of testing, known as black-box testing, neither the penetration tester nor the network defenders know about each other so the penetration tester must find a way to gather more information about the targeted network without tipping off the defender.
