What breaks when organisations rely on standing privileges instead of just in time access?

Why Standing Privileges Break Real-World Access Control

Standing privileges fail because they assume access is safe simply because it has been granted once. In practice, that creates always-on exposure for service accounts, API keys, and admin roles across cloud and SaaS systems. When compromise happens, the attacker inherits whatever the account can reach. NHIMG research shows that 97% of NHIs carry excessive privileges, which makes persistent access especially dangerous for non-human identities that are rarely used in a human-like pattern. See the Ultimate Guide to NHIs and the OWASP Non-Human Identity Top 10 for the underlying governance gap.

The problem is not only technical. standing access also weakens accountability, because teams cannot clearly prove that permissions were limited to a specific task, time window, or approval context. That makes offboarding slower, incident containment harder, and audit evidence less credible. In practice, many security teams discover the cost of standing privileges only after a compromised credential has already been reused across multiple systems.

How Just in Time Access Changes the Failure Mode

just in time access replaces persistent permission with task-bound access that is issued only when needed and revoked when the task ends. That sounds simple, but the operational shift is significant: the organisation must evaluate context at request time, not rely on pre-assigned entitlements. Current guidance increasingly favours this model for high-risk access because it shrinks the usable window for attackers and reduces the chance that dormant permissions become an incident.

In a mature implementation, JIT is paired with short-lived credentials, approval workflow, and strong workload identity. For NHIs, that means the identity should be tied to what the workload is, not just what secret it happens to hold. Where possible, teams should use ephemeral tokens, workload attestation, and policy checks that confirm the task, target resource, and time window before access is issued. NIST control guidance in NIST SP 800-53 Rev 5 Security and Privacy Controls supports this least-privilege direction, while NHIMG’s Key Challenges and Risks section explains why excessive privilege is so common in NHI estates.

• Issue access only for the approved task, resource, and duration.
• Prefer short-lived tokens over reusable static secrets.
• Revoke permissions automatically when the task completes or times out.
• Log the request context so auditors can reconstruct why access existed.

These controls tend to break down in legacy automation estates where scripts, batch jobs, and shared service accounts still depend on long-lived credentials because the application cannot tolerate frequent re-authentication.

Where Standing Privileges Still Show Up, and Why They Persist

Tighter access control often increases operational overhead, requiring organisations to balance reduced exposure against workflow friction. The hardest cases are not well-managed cloud apps, but old integrations, shared admin tooling, and third-party connections that were built around permanent access. In those environments, teams often keep standing privileges because replacing them would require application changes, token lifecycle redesign, or cross-team approval paths.

Best practice is evolving, and there is no universal standard for every environment yet. For example, some systems can support JIT through vault-issued credentials and policy-as-code, while others still need compensating controls such as stronger monitoring, tighter segmentation, and frequent access review. That is especially important when third parties hold access to internal systems, because persistent permissions outside the core security boundary are harder to track and revoke. NHIMG’s 52 NHI Breaches Analysis and the Microsoft SAS Key Breach show how long-lived access turns routine credentials into durable attack paths.

The practical takeaway is that standing privileges are not just “less ideal” than JIT. They create hidden persistence that attackers can abuse, compliance teams struggle to prove away, and operations teams often leave in place until a breach forces the cleanup.
