Detection Coverage Mapping

Detection Coverage Mapping is a cybersecurity practice that systematically identifies and visualizes which security controls can detect specific threats or attack techniques.

This process involves creating a comprehensive matrix or map that shows the relationship between potential attack vectors and the security tools, rules, or procedures designed to identify them.

The mapping process typically aligns with established frameworks like MITRE ATT&CK, which categorizes adversary tactics and techniques. Security teams use these mappings to identify coverage gaps where certain attack methods might go undetected, enabling them to prioritize investments in additional detection capabilities or adjust existing security controls.

Detection coverage maps serve multiple purposes: they help security analysts understand their defensive posture, guide threat hunting activities, and support incident response planning. By visualizing which threats are well-covered versus those with limited detection capabilities, organizations can make informed decisions about resource allocation and risk management.

Regular updates to detection coverage maps are essential as threat landscapes evolve and new attack techniques emerge. This practice is fundamental to a mature security operations program and helps ensure that detection strategies remain aligned with current threat realities.
