For improving threat detection effectiveness, what's a strategic action to take regarding logging in Microsoft Defender?

Updating logging policies to ensure complete coverage across applications is a strategic action that significantly enhances threat detection effectiveness. Comprehensive logging policies ensure that all relevant applications and services are being monitored and that critical security events are recorded. This thorough approach allows analysts to have visibility into potential threats across the entire environment, making it easier to detect anomalies, identify attacks in real-time, and respond promptly.

By covering all applications, including those that might be less obvious or not traditionally monitored, organizations can avoid blind spots where cyber threats might go undetected. This holistic logging strategy not only strengthens security posture but also facilitates compliance with regulatory requirements and supports forensic investigations in the event of a breach.

In contrast, other options could undermine threat detection. For example, automatic deletion of old logs may lead to the loss of valuable historical data that could aid in tracking long-term attacks or trends. Consolidating logs, while useful for central monitoring, would not be effective without ensuring that comprehensive logging policies are in place first. Increasing sensitivity of all detection alerts might lead to alert fatigue and could result in overlooking critical detections if not managed carefully. Therefore, ensuring complete coverage through updated logging policies is essential for effective threat detection.
