Challenges with today's approach
As we just saw, different teams (red, blue, and more) have different objectives, constraints, and approaches in a cybersecurity environment. They don't have a standardized methodology for collaboration, and this leads both teams to encounter issues, and also disadvantages the overall security posture of the organization.
The following table describes some common issues that impact both the red and blue teams. It also explains how purple teaming may help to prevent these failures.
Additionally, though each team experiences problems specific to it, we wanted to highlight a few of the issues faced by blue teams in particular, and how a new approach to security teams could help to tackle these:
As a defender or an ethical hacker, it is very likely that you recognize some (if not all) of these issues. We briefly demonstrated how purple teaming could help everyone to solve some of the problems we are facing with today's approach. Before deep-diving into the purple teaming chapter, we will finish this chapter with an overview of the regulatory landscape. Once again, this will highlight the need for a new approach, but observed this time from the point of view of regulators.
