Machine Identity Risks Drive Shift Toward Zero Standing Privilege

Security organisations are increasingly transitioning toward zero standing privilege (ZSP) for non-human identities as static service account credentials continue to provide attackers with persistent, long-term access to enterprise environments. The shift addresses a widening gap in identity security where machines often vastly outnumber human users, yet remain protected by little more than a static password or a long-lived API key.

Traditional methods such as password vaulting and rotation do not eliminate the underlying risk, as they fail to alter the access rights associated with a credential. An attacker who compromises a static secret shortly after a rotation can maintain access for the remainder of the interval, often without triggering security alerts. Recent incidents involving OAuth token abuse, including the August 2025 campaign targeting Salesforce users via the Drift integration, have demonstrated how stolen genuine tokens allow attackers to bypass multi-factor authentication (MFA) and remain undetected for extended periods.

To achieve ZSP, organisations are moving away from persistent access in favour of short-lived credentials generated on demand. This approach typically involves workload identity federation, where a service proves its identity to a policy engine—such as a CI/CD pipeline or a cloud provider—and receives a temporary, scoped token that expires automatically once the task is complete.

Security teams are advised to begin the transition by creating a comprehensive inventory of all machine credentials, including OAuth grants and third-party integrations. Assigning a clear human owner to every identity is a critical step in identifying and removing orphaned accounts that often persist for years. Once identified, high-risk assets such as CI/CD pipelines and cloud administration roles are primary candidates for early migration to OIDC (OpenID Connect) or other federated identity standards.

For legacy systems that do not support federation, security professionals suggest implementing vault-issued dynamic secrets. This method creates unique, time-bound database or application credentials for each session, preventing the use of long-lived static keys. Tracking the ratio of machine access granted on demand versus standing access provides a measurable metric for board reporting, allowing leadership to monitor the progress of identity security hardening over time.
