Who should own emergency access decisions in a policy-driven model?

Why This Matters for Security Teams

Emergency access is one of the few places where policy, operations, and audit pressure collide. If the decision to grant break glass access lives in application code, exception handling becomes inconsistent, hard to review, and easy to copy into other systems. A policy-driven model keeps the decision at the control point, where it can be logged, challenged, and revoked cleanly. That aligns with the broader NHI governance pattern described in the Ultimate Guide to NHIs and the control emphasis in the OWASP Non-Human Identity Top 10.

This matters even more because emergency access often exposes the exact weaknesses defenders are trying to avoid: standing privilege, weak evidence, and broad exception paths. NHI Management Group notes that 97% of NHIs carry excessive privileges, which makes any uncontrolled emergency pathway especially risky. In practice, many security teams encounter break glass abuse only after an incident response review, rather than through intentional design of the approval workflow.

How It Works in Practice

In a policy-driven model, the policy layer evaluates whether emergency access should be granted, while the application or target system enforces the resulting decision. The emergency rule can consider who is requesting access, what system is involved, whether there is an active incident ticket, time of day, approver status, and whether additional step-up authentication is present. That is closer to runtime authorization than static RBAC, and current guidance from NIST Cybersecurity Framework 2.0 supports that separation of policy and enforcement.

Operationally, the policy layer should do four things:

• Issue the decision, not execute the privilege change.
• Record who approved, why it was approved, and for how long.
• Attach TTL limits and automatic revocation conditions.
• Send the decision to downstream systems for enforcement and evidence capture.

This approach is consistent with the lifecycle and audit themes in the Ultimate Guide to NHIs — Lifecycle Processes for Managing NHIs and the audit perspective in Ultimate Guide to NHIs — Regulatory and Audit Perspectives. For regulated environments, the practical goal is not just to allow emergency access, but to prove that every exception was intentional, bounded, and reviewable. These controls tend to break down when teams embed approval logic directly into application workflows because the exception becomes invisible to central policy and inconsistent across services.

Common Variations and Edge Cases

Tighter emergency access governance often increases response time, so organisations have to balance speed against evidentiary control. That tradeoff is real, especially in incident response, production outages, and third-party escalations where every minute matters. Best practice is evolving, but there is no universal standard for this yet.

Some environments use dual approval for high-risk systems, while others allow a single approver plus mandatory post-event review. For NHI-driven workflows, the emergency decision may also need to account for service accounts, API keys, or delegated agent permissions rather than human identities alone. The Top 10 NHI Issues and the 52 NHI Breaches Analysis both reinforce why emergency paths must be time-bound and observable. The most common edge case is a shared production account or legacy admin path with no clean ownership, because the policy engine cannot reliably determine who is allowed to approve or revoke access.
