For organizations without a formalized incident-handling capability, the creation from scratch of a security operations center that enables centralized visibility, alerting and investigation can be a daunting task.

This book explains how to develop an effective security operations center (SOC) and provides a roadmap for continuously evolving this capability to keep pace with the tactics of the adversaries.
