What is a critical consideration when configuring AIR capabilities in Microsoft Defender for Office 365?

When configuring Advanced Investigation and Response (AIR) capabilities in Microsoft Defender for Office 365, selecting appropriate thresholds for alerts is a critical consideration. This involves determining the sensitivity levels at which alerts are generated based on user behavior, email patterns, and other factors. Setting thresholds too low can lead to alert fatigue, generating too many alerts that may not indicate genuine threats, while setting them too high may result in missing actual security incidents.

Effective alert thresholds ensure that security analysts are notified only about significant anomalies that warrant investigation, thereby enhancing the efficiency of the security operations center (SOC). This targeted approach allows teams to focus their resources on real threats rather than being overwhelmed by false positives, which can drastically improve incident response times and overall security posture.
