Entra ID Login Activity to Uncommon MS Cloud Apps
This rule detects Azure AD login activity to applications that are not part of a predefined list of first-party Microsoft Cloud Apps. This could indicate an attempt to access an unauthorized or unusual application within the Azure AD environment, potentially by a compromised account or an insider threat. The rule specifically excludes the 'On-Premises Directory Synchronization Service Account' to reduce false positives related to ADFS synchronization.
