How do organisations get started with OWASP Non-Human Identities Top 10?

How to use OWASP NHI Top 10 as a starting point

Start by translating the Top 10 into an inventory exercise. The first pass is not about scoring every item perfectly, it is about finding where service accounts, API keys, workload identities and automation credentials exist, who owns them, and whether they are still needed. If you need a broader orientation to the problem space, the Top 10 NHI Issues guide is a useful map of the most common failure patterns.

The most productive teams treat the list as a triage aid. That means using it to surface obvious exposure first, such as secrets stored in code or chat, credentials that never expire, and identities that were created for a project but never retired. A good early question is whether the identity has an owner who can answer for its purpose and rotation policy, not just whether the technical configuration exists.

It also helps to anchor the Top 10 in identity lifecycle and accountability. One of the fastest ways to improve is to separate identities that are actively used from those that are merely remembered in scripts, pipelines or third-party integrations. The NHI Ownership and Accountability Guide is especially relevant when the problem is not technical discovery but deciding who should fix or retire each identity.

What to look for in the first assessment pass

Use the Top 10 to look for patterns, not isolated objects. Missing ownership, excessive permissions, long-lived secrets and weak rotation usually appear together, because teams that do not govern one part of the lifecycle often lose track of the rest. If the inventory shows many shared credentials or repeated use of the same secret across environments, the issue is usually structural, not a one-off exception.

In practice, the first assessment should ask three questions for each identity: can it be discovered, can it be attributed to a business purpose, and can it be reduced in privilege or lifespan? That lens works well because the Top 10 is meant to expose control gaps, not to replace your own risk judgement. The relevant mechanics are often broader than the label on the identity itself, especially when automation or service-to-service access is involved.

Where organisations struggle most is in the boundary between human administration and machine use. A strong starting point is to understand how machine identities differ from workforce identities, especially when people create, approve, or reuse them informally. The Human vs Non-Human Identity guide helps teams separate ownership, lifecycle and access patterns before they try to remediate them.

For exposure ranking, prefer practical signals over theoretical severity. Long-lived credentials, high privilege, external reach, production access, and poor rotation hygiene are the combinations that usually matter first. If an identity can authenticate to critical systems and nobody can explain why it exists, it belongs near the top of the review queue.

How to turn the Top 10 into a remediation backlog

After the first inventory, convert each finding into a concrete backlog item with an owner, a target state and a decision about whether to rotate, reduce, replace or retire the identity. A remediation backlog works best when every item is tied to a visible control outcome, such as shorter secret lifetime, narrower permissions, or removal of orphaned access.

Rotation is often the most visible control, but it is not always the first one to fix. If an identity is overprivileged or poorly owned, rotating the secret without changing the access model can preserve the same risk. The better sequence is to fix ownership and scope first, then decide whether the credential should be rotated, reissued, or eliminated entirely.

For teams that need a deeper control and lifecycle reference, the Ultimate Guide to NHIs provides a fuller view of governance, lifecycle, visibility and rotation. That makes it a useful companion when the Top 10 has exposed several issues but you still need a practical operating model.

If your environment relies heavily on service accounts, the remediation path should also include the systems that issue, store and consume their secrets. The Service Account Security Guide is helpful when you need to move from discovery into enforcement, especially around least privilege and rotation discipline.

Risk and Threat Considerations

Non-human identities become risky when they are treated as durable infrastructure rather than governed access. The main exposure is that one forgotten or overprivileged identity can provide broad, persistent access long after the original business need has changed, which is why these issues often show up during incident response rather than routine review.

Failure mechanism: Attackers and insiders typically exploit weak ownership, stale secrets, excessive privilege and poor rotation to reuse or pivot through machine access without immediately triggering human-facing controls.

Impact: The result can be unauthorized access, lateral movement, data exposure, pipeline abuse, or persistence through credentials that were never retired.

Practitioner Guidance

What to prioritise: Start with identities that combine external reach, production access and weak ownership. Those are the ones most likely to create real blast radius if they are misused or compromised.

What to verify: For each high-risk identity, confirm who owns it, why it exists, where it is used, and whether the credential can be rotated or replaced without breaking dependent systems. If you cannot answer those questions, the identity is not ready for normalised operation.

Common mistake: Teams often try to “adopt the Top 10” by filling out a checklist, but the better move is to use it as a prioritisation frame for remediation work. The list is most useful when it changes backlog ordering and ownership, not when it becomes a reporting artifact.

Practitioner takeaway: The fastest way to start is to reduce uncertainty first, then reduce privilege and lifespan second. If you can establish ownership, scope and rotation discipline, the rest of the Top 10 becomes far easier to manage.
