Agent Access Control: JIT(Just-in-time) JEA( Just-enough-access)

In regulated domains like Talent (HR systems) or Finance (ERP, banking platforms), granting AI agents standing access to sensitive data and systems poses significant security and compliance risks.

Just‑In‑Time (JIT) and Just‑Enough‑Access (JEA) are critical because they enforce the principle of least privilege—granting AI agents (or users) only the permissions they need, only when they need them, and only for as long as they need them.

• agent requests elevated privileges only when it needs to perform a specific task (e.g., fetching candidate

• the system dynamically scopes permissions to the minimal set of actions and data fields required (e.g., “read-only access to payroll records for employee ID X”)

• each access request is checked against an attribute‑based policy engine (e.g., OPA, Azure PIM), which evaluates real‑time context such as time of day, agent identity, task type, and risk level •policies incorporate risk factors—unusual access patterns or high‑value transactions trigger additional approvals or deny access.

• upon task completion or expiration of the JIT window, credentials are automatically revoked, and access tokens are invalidated to prevent privilege creep •ephemeral keys or certificates are rotated after each session to eliminate reuse risks.

• every JIT/JEA grant and revoke event is logged with full context (who, what, when, why), ensuring traceability for audits and investigations •a central monitoring system watches for policy violations or anomalies and can trigger alerts
