The CISO’s Guide to Turning Strategy into Action with Threat-Led Defense

This document outlines a Threat-Led Defense operating model that bridges security strategy and execution by centering on adversary behavior mapped to MITRE ATT&CK, using coverage maps, control validation, and procedure-level intelligence to prioritize and measure defenses. It presents a five-step playbook—establish relevant threat profiles, map the defensive stack, enhance detection engineering, validate controls, and track recommendations—and highlights outcome-based metrics such as procedures coverage, control efficacy, and a confidence score, positioning Tidal Cyber’s platform as the vehicle to operationalize and report on this approach.
