Overview: Response Authority Matrix

Quick Definition

A Response Authority Matrix is a document that defines roles and decision-making authority during cybersecurity incident response activities. This matrix clearly outlines who has the authority to make specific types of decisions at different escalation levels, ensuring that incident response teams can act quickly and effectively without confusion about command structure.

The matrix typically includes various incident severity levels, from minor security events to major breaches, and maps each level to appropriate decision-makers within the organization. For example, a Level 1 incident might be handled entirely by front-line security analysts, while a Level 4 incident might require C-suite approval for actions like system shutdowns or external communications.

Key elements include authorization for containment actions, evidence preservation, system isolation, external vendor engagement, law enforcement notification, and public communications. The matrix also defines financial spending limits, legal consultation requirements, and media response protocols for each authority level.

By establishing clear authority boundaries beforehand, organizations avoid critical delays during active incidents when time is essential. The matrix should be regularly reviewed and updated to reflect organizational changes and lessons learned from previous incidents.
