The adversary is trying to break security mechanisms, pipelines, and tooling so defenders can’t see or trust what’s happening.
Defense Impairment consists of techniques that degrade, disable, or undermine the effectiveness and trustworthiness of security controls and monitoring mechanisms. These techniques are characterized by direct interference with defensive systems. The goal is to reduce defenders’ ability to detect, interpret, or respond to adversary activity.
