How should organisations manage identity security across the lifecycle?

They should treat identity as a living control state, not a one-time provisioning event. That means validating access at join, adjusting it at mover events, revoking it at exit, and recertifying it on a schedule that reflects business change rather than calendar convenience.

Why This Matters for Security Teams

identity security across the lifecycle is where most control failures actually happen. Join-time checks are easy to automate, but mover events, temporary access, offboarding, and periodic recertification are where standing privilege quietly accumulates. That matters for both human identities and NHIs, because exposed tokens, stale service accounts, and orphaned access paths become durable entry points long after the original business need has changed.

Current guidance from the NIST Cybersecurity Framework 2.0 and the OWASP Non-Human Identity Top 10 both point to the same operational reality: identity is not a one-time provisioning event, it is a continuously changing control state. NHI Management Group’s NHI Lifecycle Management Guide frames this as a governance problem, not just an IAM problem, because the attack surface grows whenever identities outlive their business purpose.

In practice, many security teams discover lifecycle gaps only after offboarding, integration sprawl, or token exposure has already created a persistent foothold.

How It Works in Practice

Effective lifecycle management starts with a clear inventory of identity types, owners, and business purpose. Human users, service accounts, API clients, certificates, and machine identities should not be managed as if they have the same risk profile. The practical model is to bind each identity to an explicit lifecycle state, then enforce controls that change when the state changes.

At join or creation, issue only the minimum access required for the approved use case. At mover events, re-evaluate access rather than layering new permissions on top of old ones. At exit or decommission, revoke credentials, disable sessions, and remove downstream entitlements. For NHIs, this should also include token rotation, secret invalidation, and dependency checks so that one identity’s retirement does not break a critical workflow. The Ultimate Guide to NHIs — Lifecycle Processes for Managing NHIs and the Guide to the Secret Sprawl Challenge both reinforce that unmanaged duplication and undocumented storage are common lifecycle failures.

• Assign a business owner and technical owner to every identity.
• Use time-bound access where possible instead of permanent entitlements.
• Automate recertification on business-triggered intervals, not just quarterly cadence.
• Track where secrets live, who can use them, and when they were last rotated.
• Log revocation outcomes, not just requests, so stale access is provably removed.

For reporting and prioritisation, the Entro Security research in The 2025 State of NHIs and Secrets in Cybersecurity notes that 91% of former employee tokens remain active after offboarding, which is exactly why exit workflows must verify that revocation actually completed. These controls tend to break down when identities are embedded in CI/CD pipelines, shared integrations, or third-party SaaS connectors because ownership, rotation, and deprovisioning are often split across multiple teams.

Common Variations and Edge Cases

Tighter lifecycle control often increases operational overhead, requiring organisations to balance security with release velocity and service continuity. That tradeoff is most visible in environments with many short-lived workloads, partner integrations, or legacy systems that cannot tolerate frequent credential changes without redesign.

Best practice is evolving for service accounts and machine identities that support always-on production processes. In some environments, calendar-based reviews are still used because business events are not well instrumented, but that is a compromise rather than a mature control. Where static review cycles remain necessary, they should be supplemented with event-driven triggers such as role change, application ownership change, vendor termination, or unusual secret usage. This is especially important for NHIs because overused identities and duplicated secrets can cause one compromise to spread across multiple systems.

The current consensus is that lifecycle governance should be continuous, but there is no universal standard for exactly how often every identity class must be recertified. The right interval depends on exposure, privilege, and change rate. Organisations that want a stronger baseline should align lifecycle reviews with the Top 10 NHI Issues and the control emphasis in the OWASP Non-Human Identity Top 10, then tune cadence based on actual business change rather than convenience.
