Organisations should manage secrets, service accounts, and privileged human access as one control problem. If tokens, API keys, and admin accounts are reviewed in separate processes, attackers can exploit the gaps between them. Unified ownership, revocation, and access review reduce the chance that a stolen identity persists unnoticed.
Why This Matters for Security Teams
Secrets and privileged identities often fail for the same reason: they are governed in different tools, by different teams, with different review cycles. That separation creates blind spots between vaults, service accounts, admin entitlements, and human break-glass access. Current guidance from the OWASP Non-Human Identity Top 10 and the NIST Cybersecurity Framework 2.0 both points toward the same operational reality: identity risk is cumulative, not siloed.
NHI Management Group has documented how frequently secrets become exposed in operational workflows, including the Guide to the Secret Sprawl Challenge and the Ultimate Guide to NHIs – Static vs Dynamic Secrets. One particularly relevant finding from The 2025 State of NHIs and Secrets in Cybersecurity is that 91% of former employee tokens remain active after offboarding, which shows how quickly gaps form when secrets and privileged access are not governed together.
In practice, many security teams discover the overlap only after a leaked token is used to reach an admin path that no one reviewed as part of the same control.
How It Works in Practice
The practical goal is to treat secrets, service accounts, and privileged human access as one identity fabric. That means one ownership model, one inventory, one revocation path, and one periodic review cycle across all privilege-bearing credentials. If a service account uses an API key, and that API key can reach a privileged system, both the secret and the underlying entitlement need the same business owner and the same expiry expectations.
Start by classifying every credential by function, not by storage location. Vault entries, CI/CD tokens, admin accounts, SSH keys, certificates, and break-glass accounts should all map to the same asset owner and the same workflow for approval, rotation, and retirement. The operational pattern is consistent with the CI/CD pipeline exploitation case study, where automation access can become privileged access if a token is reused beyond its intended scope.
- Use a single authoritative inventory for secrets and privileged identities.
- Assign a business owner and technical custodian to each credentialed identity.
- Enforce short-lived credentials where possible, with automatic revocation on task completion.
- Review secret exposure and admin entitlements in the same attestation cycle.
- Link offboarding to token revocation, not just account disablement.
Where mature controls exist, teams often tie vault events to IAM events so rotation, deprovisioning, and exception handling are coordinated. For implementation detail, the 230M AWS environment compromise is a reminder that cloud privilege often persists through multiple paths, not one. These controls tend to break down when secrets are copied into collaboration tools and emergency access is managed outside the standard review process because the inventory is no longer complete.
Common Variations and Edge Cases
Tighter governance often increases operational overhead, so organisations must balance speed against control depth. That tradeoff becomes most visible in engineering teams that rotate credentials frequently, use ephemeral workloads, or rely on emergency access during outages. Best practice is evolving, but there is no universal standard for how often every privileged secret should be reviewed; the right cadence depends on criticality, exposure risk, and whether the credential can be issued just in time.
Edge cases matter. Shared service accounts, legacy platforms without federation, and vendor-managed integrations often resist clean lifecycle management. In those environments, the right answer is usually compensating control rather than pretending the identity is well-governed. Stronger monitoring, narrower scope, explicit expiry, and documented exception approval are preferable to leaving a long-lived secret in place. The 52 NHI Breaches Analysis and the Top 10 NHI Issues both show that overused credentials and weak lifecycle discipline remain common failure modes.
For organisations building a governance baseline, the most practical rule is simple: if a secret can unlock privilege, it belongs in the same control family as the privilege itself. That is the only way to prevent clean-looking audits from masking exposed access paths in production.
