The admin account had far more power than it needed. One compromised token, and the blast radius was the entire system. Least privilege SCIM provisioning stops that from happening.
SCIM (System for Cross-domain Identity Management) automates user provisioning across platforms. It defines how identities are created, updated, and removed through a standard API. Without least privilege, your SCIM integration becomes a direct path for privilege escalation. SCIM works best when combined with a permissions model that limits each account and service to only the actions it must perform.
Least privilege SCIM provisioning means aligning your identity lifecycle with access controls that enforce the smallest possible permission set. The SCIM client should have only the rights needed to create, update, or deactivate a user. It should never own broad admin abilities for groups, roles, or privileged accounts unless absolutely necessary. This containment reduces the attack surface and limits damage if credentials are exposed.
