In the context of alert suppression in Microsoft Defender, what is a potential first action?

Identifying common false positives is a significant first step in alert suppression within Microsoft Defender. This process involves analyzing alerts that frequently occur but do not represent real security threats. By pinpointing these false positives, cybersecurity teams can adjust alert settings or suppress certain alerts to reduce noise. This enables analysts to focus on genuine security incidents, improving overall efficiency and response time. Addressing false positives helps refine the alert system, ensuring it is tailored to the organization’s specific environment and threat landscape.

The other choices, while relevant to overall security operations, do not serve the same immediate purpose. Reviewing external threat intelligence feeds and assessing alert relevancy can inform future decisions but do not directly address the immediate challenge of managing alert volumes. Triggering existing alerts for logging is also more about documenting incidents rather than refining alert accuracy. Thus, identifying false positives is a proactive step essential for streamlining alert management.
