DOD component heads will establish the means to validate AT risk management reviews within how many days of completion?

The correct answer reflects the directive that DOD component heads must establish procedures for validating Anti-Terrorism (AT) risk management reviews within 90 days of completion. This timeframe is critical because it ensures that any potential vulnerabilities identified during the risk management review are addressed in a timely manner. Establishing this timeline reinforces accountability and effective response procedures within the military, facilitating a proactive approach to risk management. Keeping reviews current and followed up on promptly is essential to maintaining the overall effectiveness of security measures against evolving threats.
