Traditionally, the Offenders (Red Team) and Defenders (Blue Team) have been considered two sides of the same security coin. While the Red team emulate an attacker exploiting a vulnerability in an organisation’s systems, the Blue team is responsible for building security controls to defend against the attackers. As both the activities are integral in improving the cyber security posture of a company, an integration between both mindsets is crucial in achieving the desired business objectives. Purple teaming process involves consistent knowledge sharing between both the Red and Blue teams for continuous process improvements:
– Defence informs the offence about their controls, monitoring and how to respond to the security incidents.
– Offence on the other hand, informs defence about TPPs (Techniques, Tactics and Procedures).
