Red teaming is a practice used to rigorously challenge an organization’s plans, systems and assumptions with an adversarial approach. It aims to overcome cognitive errors that can impair decision-making and measure the effectiveness of existing security measures. In cybersecurity, a red team simulates potential attacks, while a blue team simulates preventative actions. The practice helps identify vulnerabilities and potential improvements for cybersecurity systems, ideally improving defenses against actual attacks. It is differentiated from penetration testing primarily by its stealthy and unannounced approach.
