API security checklists and NHI governance: what teams miss

TL;DR: API-related attacks are accelerating as insecure APIs and exposed tokens keep creating direct paths into sensitive systems, with the article citing 439 AI-related CVEs in 2024 and more than half of organisations reporting an API-related incident in the past 12 months, according to Apono. The real issue is not checklist fatigue but whether API governance now treats NHIs, scoped permissions, and request-level accountability as first-class controls.

By the numbers:

• In 2024, researchers catalogued 439 AI-related CVEs, a staggering 1,025% increase over the prior year, and nearly 99% were tied to insecure APIs.
• 12 months., of organizations reported an API-related incident in the past 12 months.

Questions worth separating out

Q: How should security teams govern API access for service accounts and tokens?

A: Security teams should treat API callers as identities with owners, scopes, and lifecycles, not as anonymous technical plumbing.

Q: Why do APIs create so much risk for non-human identities?

A: APIs give non-human identities direct execution paths into applications, data stores, and partner systems.

Q: What breaks when API keys are long lived and hard to revoke?

A: Long-lived API keys keep access alive after the original task, owner, or environment has changed.

Practitioner guidance

• Inventory every API-exercising identity Create a complete register of service accounts, API keys, bots, partner credentials, and automation accounts.
• Replace standing API privilege with short-lived scopes Issue narrowly scoped, time-bound permissions for API calls and automate revocation when the task ends.
• Enforce request-level authorisation checks Apply RBAC or ABAC at the endpoint, resource, and object level instead of relying on coarse gateway authentication.

Apono's full article covers the operational detail this post intentionally leaves for the source:

• Step-by-step control guidance for each checklist area, including authentication, secrets handling, and API inventory
• Implementation patterns for JIT and JEP access flows, including how temporary permissions are issued and revoked
• Practical logging and audit design details for tying identity, scope, and request activity together
• Operational examples for shadow API discovery, partner credential scoping, and incident response runbooks
