Purple Team
Definition
Purple teaming is a collaborative exercise in which the offensive red team and the defensive blue team work together to test and improve security controls. It combines attack and defence.
In purple teaming, red and blue teams work transparently together rather than against each other. The attacking party shares techniques and findings in real time, so the defending team can immediately test whether its detection systems signal the attack.
The result is direct feedback on the effectiveness of security controls, and concrete improvements to detection rules, incident response procedures and security configurations.
Purple teaming is particularly efficient for mature security teams that want to rapidly improve their detection capabilities. DEFION offers structured purple team exercises.
