What breaks when organisations keep standing privilege for accounts that are only used occasionally?

Why This Matters for Security Teams

Occasional-use accounts are often treated as harmless because they are not logged in every day, but standing privilege means the access remains live between uses. That creates a persistent blast radius if the account is compromised, misused by automation, or forgotten after a project ends. The risk is not theoretical: NHI Mgmt Group reports that 97% of NHIs carry excessive privileges, and 80% of identity breaches involved compromised non-human identities such as service accounts and API keys in the Ultimate Guide to NHIs.

For teams managing service accounts, API keys, or agent credentials, the core issue is not frequency of use. It is whether access exists when it is not needed. That is why current guidance increasingly favors just-in-time access, short-lived secrets, and explicit revocation over “keep it on in case it is needed.” The OWASP Non-Human Identity Top 10 frames standing privilege as a recurring design flaw, not a minor hygiene issue. In practice, many security teams encounter account abuse only after a dormant credential is reused outside its original purpose, rather than through intentional review.

How It Works in Practice

When an account is only needed occasionally, its privilege model should match that usage pattern. Static entitlements keep the identity perpetually authorized, even though the actual task may occur once a week, once a quarter, or only during incident response. The practical alternative is to bind access to task context and issue credentials only when the request is approved, time-bound, and traceable. That usually means combining privileged access management with just-in-time provisioning, workload identity, and policy checks at request time.

In a mature implementation, the occasional-use account is not deleted every time it goes idle. Instead, it is kept in a disabled or unprivileged state, then activated briefly for a named purpose. For non-human identities, that can mean short-lived tokens, certificate-based workload identity, or ephemeral secrets that are automatically revoked after completion. The Ultimate Guide to NHIs highlights why this matters: long-lived credentials and excessive privilege are among the most common paths to compromise.

• Use JIT approval for access that is needed less than continuously.
• Set tight TTLs so dormant credentials cannot be replayed later.
• Separate authentication from authorization so an identity can exist without permanent power.
• Log task context, approver, and revocation time for auditability.
• Rotate or retire credentials after each high-risk use, not on a vague annual cycle.

For implementation detail, the OWASP Non-Human Identity Top 10 is useful for mapping common failure modes such as leaked secrets, overprivileged service accounts, and missing lifecycle controls. These controls tend to break down when legacy applications require hardcoded credentials or when operational teams cannot tolerate the latency of approval and issuance during production incidents.

Common Variations and Edge Cases

Tighter privilege controls often increase operational overhead, requiring organisations to balance faster recovery against reduced exposure. That tradeoff is real for incident response accounts, batch jobs, and third-party integrations, where “always available” access has historically been used to reduce downtime. Current guidance suggests treating those cases as exceptions with compensating controls, not as a reason to keep broad standing privilege everywhere.

There is no universal standard for every environment yet, but best practice is evolving toward context-aware authorization, automated revocation, and separate paths for emergency access. Some teams retain a break-glass account, but even then the account should be isolated, heavily monitored, and excluded from normal workflows. Other environments may need long-lived machine certificates for technical reasons, yet those should still be scoped narrowly and rotated aggressively. The general rule remains simple: if the account is used occasionally, its privilege should be temporary, not permanent. This is especially important where service accounts are shared across systems, because one dormant credential can silently become a cross-environment pivot point.
