The course covers the use of open source tools and websites for system configuration, penetration testing, and control testing. You will use Linux and Windows command lines and unleash an attack on target servers and analyze the results. Attacks and analysis of will expose you to live attacks in a controlled environment where students can see first-hand the adversary realm of possible actions, how to detect, mitigate, and counter such activities.
