Gotham Werx has a really simple and good artile that provides a good intro to understand what Red Teaming is.
The Red Team Podcast, however, dives deeper into the subject of what true red teaming is and discusses the mindset required to be an effective “Red Teamer.” Ironically, the more you listen to the podcast, the more you learn that red teaming is quite difficult to define. It spans numerous subjects of thought and study. By it’s very nature, it proves difficult to provide a short and concise definition that encompasses all of its elements. However, with all of the information provided in the podcast, the hosts (Uri and Dan) constantly field two questions in particular. Hopefully, I can provide an answer to both that will be easy for average folk to understand.
