This presentation will give the attendees an understanding of some of the more popular open source penetration testing tools and how they align to the Lockheed Martin Kill Chain. Tools will include Metasploit, BurpSuite, Pacu, Shodan and others. We will also cover tools that require that the user already has access to the environment, like ScoutSuite and Prowler. Demonstrations of a subset of tools will also be given. Through discussing and demonstrating these tools, the goal is to give attendees a better idea of how to secure their environments
