Critical Security Alert Response Runbook

This document is a Critical Security Alert Response Runbook that outlines the procedures followed by Proactive Risk's Security Operations Center (SOC) when a critical security alert is identified and confirmed. It details the standard operating procedures, including roles and responsibilities, the critical alert response lifecycle, and the communication plan with clients. The runbook serves both internal and external audiences, providing SOC analysts with a clear framework for action and clients with transparency regarding the response to serious threats. The document emphasizes a technology-provider agnostic approach, ensuring that the response process remains consistent regardless of the detection technology used. It includes a severity classification system that triggers the runbook only for confirmed or high-confidence critical alerts. The runbook also specifies the scope and applicability, defining what is included and excluded from its procedures, and it establishes guiding principles that govern the response to critical alerts.
