WHAT MAKES A “GOOD” DETECTION?

Summary from the TLDR InfoSec newsletter

The Shannon Signal Score is a way to combine qualitative and quantitative metrics to evaluate the quality of a signal based on the organization's context and the specifics of the threat. It combines qualitative and quantitative metrics to evaluate signal quality by considering threat alignment, detection integrity, operational costs, impact potential, and utility. The score uses weighted components including Threat Alignment and Coverage (measuring detection's threat alignment and attack surface coverage), Detection Integrity (quantifying effectiveness), Operational Cost (maintenance and false positive overhead), Impact and Risk Potential (threat impact assessment), and Utility (organizational value).
