Incident Response Team Structure: Roles and Responsibilities

Effective incident response requires a well-structured team with clearly defined roles and responsibilities. According to the NIST Computer Security Incident Handling Guide, organizations with structured incident response teams reduce mean time to resolution (MTTR) by an average of 45%. The SANS Incident Handler's Handbook emphasizes the importance of clear team structure. This guide covers how to structure incident response teams with clear roles and responsibilities.
