Roles Are Not Being Used

Sigma Rules

View Source
Summary
This detection rule identifies instances where users in a cloud environment have been assigned privileged roles but are not actively using those permissions. The focus is on Azure Privileged Identity Management (PIM), particularly through monitoring risk event types called 'redundantAssignmentAlertIncident'. The rule aims to enhance security within Azure by ensuring that unnecessary privilege escalations and persistent attack vectors are mitigated. If these privileged roles are not utilized over a specified timeframe, it may indicate oversight in role management or potential security concerns, as attackers often seek to exploit unused roles to gain unauthorized access. Therefore, this alert is crucial for maintaining a secure role assignment and governance strategy within Azure environments.
