They should treat delegated access, service accounts, and supplier credentials as continuity risks, not just access-control records. If those identities cannot be inventoried, constrained, and revoked during disruption, recovery will be slower and broader than it should be.
How IAM and resilience should be planned together
Public-sector organisations should design IAM as part of continuity, not as a separate administrative control. The practical question is whether essential access can still be discovered, constrained, and revoked when staff are unavailable, suppliers are degraded, or recovery teams are operating under stress. If the answer is no, the identity layer becomes a recovery dependency.
That means resilience planning has to account for who can still act, how those privileges are bounded, and which break-glass paths are safe enough to survive disruption without becoming permanent exceptions. Lifecycle processes for managing NHIs matter here because inventory, ownership, rotation, and offboarding are the mechanisms that let continuity teams distinguish essential access from leftover access.
In government settings, this is especially important for service accounts, delegated access, and supplier credentials because those identities often outlive the teams that created them. Public-sector identity security guidance is relevant because resilience scenarios often depend on federal-style zero trust expectations, strong MFA, and the ability to keep core services operating without overextending privileged access.
What changes during disruption?
Under normal conditions, IAM is often treated as a governance and administration function. During an incident, it becomes an operational control for containment, restoration, and service prioritisation. The identities that matter most are usually not human users, but the accounts that run integrations, automation, and inter-system handoffs. Those are the accounts that keep applications talking to each other when people are busy restoring services.
A resilient IAM design therefore needs clear answers to three questions: which identities are essential to restore first, which can be paused without breaking public service delivery, and which must be rapidly disabled if compromise is suspected. If those boundaries are not known in advance, recovery teams end up granting broad temporary access just to get systems back online.
That is why lifecycle visibility is more important than static documentation. NHI lifecycle management is the right operational lens for this because it forces organisations to maintain ownership, rotation discipline, and deprovisioning pathways that still function when normal business workflows do not.
How to build IAM into resilience planning
The strongest approach is to map identities to business services and recovery tiers, not just to departments or technology platforms. For each critical service, resilience planning should identify the accounts, keys, certificates, and delegated permissions required to restore it, then define how each will be validated, reissued, or revoked if the primary control plane is unavailable.
That mapping should also cover supplier and platform access. Public-sector outages often become longer when third-party credentials are hidden in procurement files, shared in ticketing systems, or owned by a contractor who is unavailable during the incident. Good resilience planning makes those dependencies explicit, assigns an internal owner, and tests whether access can be rotated or revoked without waiting on the supplier.
At programme level, the useful question is not whether the organisation has an IAM policy, but whether it can execute identity recovery under pressure. An identity security programme helps because resilience requires RACI clarity, governance, and roadmap discipline across human, non-human, and AI-driven access paths. The NHI definition and overview is useful here because it keeps the focus on the actual machine and service identities that continuity depends on.
Risk and Threat Considerations
IAM failures during disruption are not just administrative problems. If delegated access or supplier credentials cannot be inventoried and revoked quickly, an incident can become a prolonged access problem, with wider blast radius, slower containment, and longer recovery. In public-sector environments, that can also create service continuity risk when critical systems depend on accounts that no one can confidently trace or disable.
Failure mechanism: Hidden or overprivileged service identities, stale supplier access, and undocumented break-glass paths survive the incident because the organisation cannot prove where they are, who owns them, or how to revoke them safely under pressure.
Impact: Recovery takes longer, emergency access expands beyond what is necessary, and a compromise can persist through the very period when the organisation believes it is restoring control.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
NIST CSF 2.0, NIST SP 800-53 Rev 5 and CSA Cloud Controls Matrix set the technical controls, while ISO/IEC 27001:2022 defines the regulatory obligations.

|---|---|---|
| NIST CSF 2.0 | GV.SC-01 — Roles, Responsibilities, and Authorities | Defines accountability for supplier and shared-access dependencies in continuity planning. |
| RC.RP-01 — Recovery Plan Implementation | Recovery plans must work for the identities that restore and isolate critical services. | |
| Recommendation — Assign clear ownership for delegated and third-party identities used in critical services. Test identity recovery steps during failover and incident exercises. | ||
| NIST SP 800-53 Rev 5 | CP-2 — Contingency Plan | Contingency plans must include identity dependencies that affect service restoration. |

| IA-5 — Authenticator Management | Resilience depends on being able to rotate or revoke credentials and other authenticators. | |
| Recommendation — Include IAM dependencies, break-glass access, and revocation steps in contingency plans. Maintain a current inventory of privileged, delegated, and supplier accounts. Set tested rotation and revocation procedures for service credentials and secrets. | ||

Practitioner Guidance
What to prioritise: Build a recovery inventory for every identity that can affect a critical service, including service accounts, delegated admin roles, certificates, and third-party access. If an identity cannot be named during a tabletop or failover exercise, it is not ready for resilience planning.
What to verify: Test whether you can rotate or revoke those identities during an outage without relying on a single admin path or an unavailable supplier. The control is only credible if the recovery team can demonstrate the action sequence, not just describe it.
Practitioner takeaway: Resilience planning should assume that identity is part of the recovery path, because the accounts that keep services running are also the accounts that can delay recovery if they are not bounded, owned, and recoverable.
