Before giving an enterprise AI agent more tools, define what it is authorized to do, on whose behalf, and within which limits. A practical authority map can record the agent’s owner and identity, delegated authority, data and tool access, permitted actions and resources, approval gates, audit evidence, and revocation path. This is a useful governance artifact synthesized from current guidance—not a formal, universal standard.
Why tool access changes the governance question
A tool is not just another feature: it gives an agent a way to retrieve information or act on a system. The risk depends on both the tool’s capabilities and the environment it can affect. NIST’s agent tool-use taxonomy distinguishes read-only retrieval, constrained-write application or API use, and write-capable coding or computer-use systems; it also treats trusted and untrusted environments as a separate consideration. NIST’s workshop account describes tool taxonomies as a way to make agent capabilities and deployments more transparent.

That distinction helps avoid treating all tool access as equivalent. Reading an approved knowledge source is materially different from changing a business record, deploying code, or operating a system through a computer-use interface. An agent connected to untrusted content or an untrusted environment also needs consideration distinct from one operating only within controlled enterprise resources.
NIST says that agents accessing diverse data, tools, and applications need appropriate identification and authorization controls. Its February 5, 2026 announcement frames identity and authorization as a practical challenge; it does not establish that every agent is unsafe or that a diagram alone prevents attacks.
What an authority map should contain
Use the map to make the agent’s authority explicit enough to implement, review, and revoke. The fields below synthesize recommendations from NIST, Microsoft, and OWASP; none of those sources publishes this exact list as a mandatory schema.
| Map field | What to record | Governance question |
|---|---|---|
| Owner and delegator | The accountable business or technical owner, plus the user or organizational authority on whose behalf the agent acts. | Who is accountable for the agent, and whose authority does it use? |
| Identity and lifecycle | How the agent is identified, provisioned, monitored, disabled, or revoked. | Can administrators reliably distinguish this agent and end its access? |
| Data scope | Specific data sources the agent may read or change, including the permission context when it acts for a user. | Which information can it reach, and under whose permissions? |
| Tools and actions | Approved tools and allowed operations, distinguishing read-only, constrained-write, and write access where useful. | What may the agent do with each tool—not merely which tools are installed? |
| Resources and environment | Systems and resources in scope, and whether actions touch trusted enterprise systems or untrusted content or environments. | Where can the agent operate, and what trust assumptions apply? |
| Approval boundary | Actions requiring human approval or a separate authorization check, especially sensitive or irreversible operations. | Which actions must not proceed on the agent’s authority alone? |
| Evidence and response | Logs identifying the agent and its authority context, monitoring for misuse, and an incident path that preserves evidence and revokes access. | Can responders understand what happened and stop further activity? |
Keep the entries specific. “Can use the finance tool” is less useful than naming the allowed operation, data or resource boundary, and whether approval is needed. The map is valuable only when its limits are enforced by identity, tool, and application controls.

Why delegated authority needs explicit limits
Delegation can create a confused-deputy problem: an agent may use its own privileged identity to perform an action that the requesting user could not perform. Microsoft’s shared-responsibility guidance identifies this risk and says organizations retain responsibility for agent data, identity and least privilege, action authorization, human oversight, and acceptable-use governance. Microsoft’s guidance also makes clear that responsibilities vary with deployment model; a control plan should account for the actual IaaS, PaaS, or SaaS arrangement rather than assume one division of duties fits all.

OWASP’s AI Agent Security Cheat Sheet recommends minimum necessary tools, per-tool permission scopes, and explicit authorization for sensitive operations. Its concise rule is: “Grant agents the minimum tools required for their specific task.”
Rank #3
High-impact actions deserve a stronger gate than routine retrieval. Financial, administrative, externally visible, or irreversible operations can cause consequences that are difficult to undo. Depending on the action, the control may be a human approval, a per-action authorization check, or both. Approval should be tied to the specific action and authority context, not treated as a blanket permission for everything the agent might do later.
How to define and operationalize the map
Use this sequence as a governance workflow, adapting it to the agent’s task and deployment. It is a practical synthesis of published recommendations, not a tested implementation procedure.
- Inventory the agent and its authority. Record its owner, delegating principal, deployment model, connected data, and tools. Include the identity used when acting for a person or organization.
- Bound access to the task. State the task the agent is meant to perform, then restrict data, actions, resources, and tools to what that task requires. OWASP’s minimum-tools guidance and Microsoft’s task-scoped authorization pattern support this least-privilege approach. Microsoft’s agent identity guidance describes defined identity, scope, tool access, auditability, action allowlists, and revocation.
- Classify operations and environments. Separate read-only access from constrained writes and broader write capability where that distinction helps. Record whether the agent interacts with trusted enterprise systems, untrusted content, or both.
- Set gates at the action boundary. Identify sensitive or high-impact operations that require explicit authorization or human approval. Check authority for the specific action rather than relying only on a broad grant made when the agent was configured.
- Make activity reviewable and stoppable. Log tool calls and the permission context in which they occurred, monitor for unusual access, and establish an incident response path. Verify that disabling the agent or revoking its access works across its connected systems.
- Reassess when the operating conditions change. Update the map when the agent gains a task, tool, connected system, greater autonomy, or a changed deployment condition.
How to compare governance approaches
When evaluating an internal design or a governance capability, compare whether it addresses the authority questions that matter in your deployment. These are comparison axes, not a vendor ranking or a claim that one product necessarily covers every control.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errors- Identity and ownership: Can the agent be identified distinctly, tied to an accountable owner, and managed through its lifecycle?
- Scope granularity: Can permissions be narrowed by data, tool, action, and resource rather than granted as a broad bundle?
- Delegation and enforcement: Can access reflect who delegated authority, and can authorization be checked for each consequential action?
- Approval controls: Can sensitive operations be held for human approval or a separate authorization decision?
- Audit and response: Do logs preserve the agent’s identity and permission context, and can access be monitored and revoked?
- Deployment coverage: Do controls work across the actual model, hosting arrangement, and connected systems, with responsibilities clear for each part?
What current standards work does—and does not—establish
NIST’s February 5, 2026 announcement describes interest in launching an NCCoE project to demonstrate how identity standards and practices could apply to software agents. The associated concept paper discusses OAuth, OIDC, SPIFFE/SPIRE, SCIM, and NGAC among relevant approaches, with a practical implementation guide described as a desired future outcome. That is a developing initiative, not a completed NIST agent-identity standard. The concept paper should be read in that context.
Accordingly, an authority map is best treated as a practical way to organize decisions and connect them to enforceable controls—not as a certification, guarantee against attacks, or substitute for identity, authorization, monitoring, and incident response.
