Threat-Informed Defense
Threat-informed defense is a security approach that uses real adversary behavior and threat intelligence to guide what defenses to build, tune, validate, and prioritize.
What Is Threat-Informed Defense?
Instead of treating all risks equally, this approach focuses on the techniques most relevant to the organization's threat landscape. Teams use adversary data, ATT&CK mappings, validation exercises, and detection outcomes to shape a defense program that reflects realistic attacker behavior.
What It Looks Like in Practice
- Technique Prioritization: Focus on the behaviors that matter most
- Coverage Mapping: Understand where controls and detections are strong or weak
- Continuous Validation: Regularly test whether defenses still work
- Operational Learning: Feed exercise results back into tuning and response plans
Why It Matters
Threat-informed defense improves efficiency by aligning defensive investment with the threats that are most likely to target the organization or produce the greatest operational impact.
