Security professionals responsible for defending systems and responding to attacks.
The blue team comprises defenders—security professionals responsible for protecting systems, detecting threats, and responding to incidents. In red team/blue team exercises, the blue team defends against red team attacks, testing detection capabilities, response procedures, and overall security effectiveness. Blue team activities include security monitoring, incident response, threat hunting, and security operations. The term originates from military exercises where blue represents friendly forces.
Why It Matters
The DSC Perspective:
Blue team effectiveness determines how well your organisation detects and responds to attacks. Red team exercises test blue team capabilities. Investing in blue team skills and tools improves your overall security posture.
