Detection Coverage Index: Aligning Detections with Real-World Threats

Binary Defense has introduced a groundbreaking approach to measuring detection coverage, bridging the gap between perceived and actual security posture.

The Problem with Traditional Methods

The traditional method of measuring detection coverage relies on rule counts, alert volumes, and framework alignment, which often fails to account for the nuances of real-world attacks.

According to Aaron Estes, VP of Product at Binary Defense, “Security teams deserve metrics that reflect how attacks actually happen, not how frameworks describe them.”

Introducing the Detection Coverage Index (DCI)

DCI uses a confidence score to evaluate coverage across MITRE ATT&CK tactics, techniques, and sub-techniques, always in the context of a defined threat model. This approach ensures that coverage reflects real-world attack paths, rather than theoretical mappings.

DCI maps coverage to specific threat profiles, such as ransomware, data theft, business compromise, and cryptojacking.
It uses a sophisticated algorithm that models adversary behaviors, tracks how those behaviors appear in telemetry, and maps coverage only where it’s relevant to each threat profile.
The score is measured and weighted relative to the organization’s specific risks, making it a valuable tool for identifying areas where resources should be concentrated to enhance protection.

Benefits of DCI

By incorporating DCI into NightBeacon Detect, Binary Defense provides executives with a clear, leadership-facing evidence of risk reduction, enabling informed decision-making and strategic security conversations.

As the landscape of threats continues to evolve, having a reliable metric like DCI will become increasingly essential for organizations seeking to stay ahead of emerging threats.

Aaron Estes further explains, “Detection Coverage Index is how we make the rigor of our detection engineering visible, connecting real-world threats to the detections we build so our customers can see exactly what they are protected against and how that protection grows over time.”

Conclusion

Binary Defense’s innovative approach to measuring detection coverage, through the Detection Coverage Index, bridges the gap between perceived and actual security posture. It provides a confidence score that reflects the effectiveness of an organization’s security measures and helps identify areas where resources should be concentrated to enhance protection.
