Episode 46 — False Positives and False Negatives

This episode teaches you to treat tool output as a starting point, not a verdict, by understanding why false positives and false negatives occur and how to respond with disciplined validation. You’ll define false positives as reported issues that are not actually present and false negatives as real issues that scanning or enumeration missed, then connect each to practical causes like misleading banners, proxies, generic signatures, filtering, timing, permissions, and coverage gaps. We’ll cover how environmental changes during a scan can skew results, why one data point should not drive a conclusion, and how to cross-check findings with independent clues to raise confidence without escalating risk. You’ll practice scenario reasoning where a version string suggests exposure but behavior contradicts it, and where filtering hides services even though other signals imply reachability. By the end, you’ll be able to choose next steps that reduce error, document confidence clearly, and avoid the common mistakes of dismissing alerts too quickly or trusting silence as proof of safety.
