The rule 'Invalid PIM License' is designed to detect situations where an organization fails to maintain the required licenses for Microsoft Entra Privileged Identity Management (PIM). If the organization does not possess a Microsoft Entra Premium P2 license or has not configured proper licensing as per Microsoft guidelines, this rule will trigger an alert to ensure compliance. This can be critical for organizations using PIM to manage privileges, as being out of compliance can lead to security risks associated with mismanaged access rights. The detection logic is straightforward; it monitors for a specific risk event type labeled as 'invalidLicenseAlertIncident'. If this event is detected, it indicates an issue with licensing which needs to be addressed immediately to prevent unauthorized privilege escalation and to maintain compliance within the Azure framework. This rule is categorized with a high alert level, indicating that immediate attention should be given when triggered. Investigations into false positives related to license expiry are advisable to ensure valid alert responses.
