A "Blue Team" refers to a group of cybersecurity professionals responsible for defending an organization's information systems from cyber threats. Their primary role is to monitor, detect, and respond to security incidents, ensuring the integrity and confidentiality of data. Blue Teams implement security measures, conduct risk assessments, and develop incident response plans to protect against potential attacks. In contrast to the "Red Team," which simulates attacks to test defenses, the Blue Team focuses on maintaining security and improving resilience. They often use tools and techniques related to network security, threat intelligence, and vulnerability management to safeguard systems and respond effectively to incidents.
