John has been tasked with building a team that combines techniques from attackers and defenders to help protect his organization. Which of the following types of the team is he building?

Purple teams are a combination of red and blue teams intended to leverage the techniques and tools from both sides to improve organizational security. A red team is a team that tests security by using tools and techniques like an actual attacker. A blue team is a defender team that protects against attackers (and testers like red teams!). White teams oversee cybersecurity contests and judge events between red teams and blue teams.
