CISSP study material · question 69 of 500

An adversary edits the endpoint detection agent's configuration and deletes the log forwarding pipeline, so alerts stop reaching the security operations centre and analysts can no longer trust their consoles. In the current MITRE ATT&CK Enterprise matrix of fifteen tactics, which tactic describes this behaviour?

  1. Stealth, concealing the adversary's actions so that they pass for normal behaviour in the environment
  2. Defense Impairment, disabling defensive tooling and telemetry pipelines so analysts lose visibility
  3. Impact, disrupting the availability or integrity of the organisation's business systems and data
  4. Persistence, holding the foothold across restarts, credential changes and routine maintenance work

Answer: B. Defense Impairment, disabling defensive tooling and telemetry pipelines so analysts lose visibility

Defense Impairment targets the defensive tooling and telemetry themselves. Stealth is the look-alike trap: it covers an adversary blending into normal activity rather than breaking the sensors.
