You get visibility without accountability. A discovered agent can still operate with exposed credentials, unclear entitlement scope, or no lifecycle owner to approve removal. That leaves the organisation with an inventory that looks complete but does not actually reduce exposure or support audit evidence.
Why This Breaks Security Operations
When discovery does not lead to ownership, the organisation ends up with a record of the agent but no accountable party for its access, secrets, or shutdown. That is especially risky for autonomous workloads, because agents can continue acting long after the original project team has moved on. Current guidance from the OWASP Agentic AI Top 10 and the NIST AI Risk Management Framework both point to governance gaps as a core risk, not an administrative detail.
For AI agents, ownership is the control that converts inventory into action. Without it, no one is responsible for entitlement review, credential revocation, or deciding whether the agent should remain in service. That leaves exposed secrets, stale permissions, and audit evidence that cannot prove who approved the agent’s continued operation. NHIMG’s OWASP NHI Top 10 and research such as Moltbook AI agent keys breach show how quickly exposed agent credentials can become a live incident. In practice, many security teams discover the gap only after an agent has already been removed from a project but not from production.
How Discovery Must Hand Off to an Owner
Discovery is only useful when it triggers a defined handoff. For agentic systems, that handoff should assign a business owner, a technical owner, and a runtime control owner so accountability covers intent, implementation, and operations. The owner then confirms what the agent is allowed to do, what secrets it uses, where it runs, and what evidence proves it is still needed. This aligns with the runtime emphasis in CSA MAESTRO agentic AI threat modeling framework and the control-by-control thinking in MITRE ATLAS adversarial AI threat matrix.
In practice, mature programs tie discovery to a workflow that requires:
- an assigned owner before the agent can stay active
- credential inventory linked to the agent, not to a shared team bucket
- expiry or review dates for all secrets and tokens
- an explicit approval path for decommissioning or re-scoping
- evidence that the agent’s access matches its current task
This is where workload identity matters. Agents should be identified by cryptographic workload credentials and short-lived tokens rather than long-lived shared secrets, because ownership is enforceable only when the runtime identity is clear. That approach is consistent with the practical lessons in NHIMG’s Ultimate Guide to NHIs — 2025 Outlook and Predictions and with the credential abuse patterns described in the NHIMG article OWASP Agentic Applications Top 10.
These controls tend to break down when agents are embedded in fast-moving delivery pipelines with no named service steward, because discovery data arrives faster than change management can assign accountability.
Common Cases Where Ownership Still Fails
Tighter discovery often increases process overhead, requiring organisations to balance visibility against the friction of maintaining accurate ownership records. Best practice is evolving, but there is no universal standard yet for how to classify every agent, especially when one model instance spawns sub-agents, temporary connectors, or tool-specific execution identities.
One common edge case is the shared platform team. Discovery may correctly identify the agent, but if ownership remains with a central operations group, no product team feels responsible for its business need or removal. Another case is outsourced or vendor-managed agents, where the operational owner and the risk owner are not the same entity. In both cases, the fix is not just naming a contact. It is documenting who approves access, who can rotate or revoke secrets, and who must sign off when the agent’s purpose changes. The NHIMG research on LLMjacking: How Attackers Hijack AI Using Compromised NHIs reinforces why exposed credentials and unclear custody are dangerous together.
Where the environment uses multi-agent orchestration, discovery can also fail if each sub-agent inherits access from a parent workflow without independent ownership. That creates a blind spot for audit and for incident response, because there is no single person who can prove the chain of responsibility. In that environment, current guidance suggests treating each operational identity as a managed NHI with its own owner, lifecycle, and revocation path.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Agentic AI Top 10, OWASP Non-Human Identity Top 10 and CSA MAESTRO address the attack and risk surface, while NIST AI RMF and NIST CSF 2.0 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Agentic AI Top 10 | NHI-01 | Discovery without ownership leaves agent identity and accountability unresolved. |
| OWASP Non-Human Identity Top 10 | NHI-03 | Unowned agents often retain stale secrets and unmanaged lifecycle risk. |
| CSA MAESTRO | MAESTRO emphasizes governance and runtime controls for agentic systems. | |
| NIST AI RMF | AI RMF requires governance and accountability for high-impact AI use. | |
| NIST CSF 2.0 | GV.OV-01 | Governance oversight breaks when discovered assets lack accountable owners. |
Maintain an ownership register that links every agent to governance, review, and decommissioning.
