System user

IDM/IGA Domain

Definition

Account in a system designated for system/service use rather than human use — service accounts, application identities, integration accounts. Subject to NHI lifecycle (create/rotate/decommission tied to workload) rather than human JML. OWASP NHI Top 10 catalogues risks specific to system users.

Application
Best practices: documented owner per system user, automated credential rotation, scoped permissions (least privilege), monitoring for unusual usage patterns (NHI behaving like human). NHI-specialized platforms: Astrix, Aembit, Oasis Security.
