AI agents that can use organizational data, tools, and applications need more than a login: they need an identifiable identity, narrowly bounded permissions, oversight, and an audit trail. Treating them “like staff” is a governance analogy—not a reason to give software agents human accounts or broad employee-level access.
Why AI agents need to be managed differently
A system that only generates text has a different risk profile from one that can retrieve information, send email, change records, run code, or trigger workflows. Once an agent can take actions through connected tools and applications, its access can affect data and operations beyond the conversation where a person asked for help.

NIST’s National Cybersecurity Center of Excellence describes agents as software systems that use data and algorithms to autonomously perform tasks. Its resource hub identifies information retrieval, workflow automation, software development, and cybersecurity operations among the uses organizations are pursuing. These are examples of use cases, not a measured adoption rate.
The practical shift is from asking only “What can this model say?” to asking “What can this agent do, under whose authority, and how will we know what happened?” Existing application and identity controls remain important, but they may not fully address an agent’s ability to interpret instructions and act across connected systems.

What it means to treat an agent “like staff”
For governance, the analogy means assigning responsibility and controls to an agent as an operational actor. It does not mean the agent is a person, can be held accountable like an employee, or should inherit a human account. A distinct, attributable identity helps an organization connect activity to the agent and the authorization it was given.
NIST’s proposed work on software-agent identity and authority highlights identification, authorization, auditing, non-repudiation, and prompt-injection mitigation. Those are practical control questions: can the organization distinguish one agent from another, limit what it can do, and reconstruct which actions it took?
What access should an AI agent have?
Give an agent only the data and tools needed for its defined task. Its access should be explicit and bounded across the systems it can reach, rather than inherited from a person or granted broadly for convenience. In particular, unrestricted access to sensitive data or critical systems increases the consequences of mistakes, misuse, or manipulated instructions.

- Separate identity and authority: Make the agent’s activity attributable to its own identity and authorization, rather than obscuring it under a shared or human account.
- Restrict consequential actions: Require human review or approval where an action could materially affect people, finances, sensitive information, or critical operations.
- Review access over time: Reassess permissions as the agent’s purpose, connected tools, or organizational risks change.
Identity is necessary for accountability, but it does not make an agent safe or reliable by itself. An agent with a clear identity can still be given excessive permissions or act on harmful instructions.

How to manage an AI agent in practice
- Inventory the agent and its connections. Record its purpose, owner, identity, data sources, tools, applications, and the actions it is permitted to take.
- Set a narrow authorization boundary. Allow only the access needed for the task. Avoid broad or unrestricted permissions, especially for sensitive data and critical systems.
- Choose where human oversight is required. Decide which actions the agent may take independently and which require a person to review or approve them.
- Threat-model how the agent could be misused or diverted. Consider prompt injection, privilege escalation, unexpected behavior, and gaps in accountability. Assess how an attacker or untrusted input might cause the agent to misuse its tools or access.
- Monitor activity and keep records. Track actions against the agent’s identity and authorization so that unusual behavior can be investigated and relevant activity audited.
- Reassess controls regularly. Review the agent’s permissions, oversight, and monitoring as its role or operating environment changes, and conduct security assessments rather than treating approval as permanent.
This approach follows the direction of joint guidance announced by CISA and partner agencies in May 2026: align agent risk management with existing cybersecurity frameworks, use layered defenses and strong identity management, maintain oversight, and conduct threat modeling, continuous monitoring, and regular security assessments.
Risks to include in an agent threat model
Prompt injection
Instructions embedded in content an agent reads may try to redirect its behavior or persuade it to misuse connected tools. Consider how the agent handles untrusted input and whether a manipulated response could lead to an unauthorized action.
Privilege escalation and excessive reach
An agent may have more access than its task requires, or an attacker may try to use the agent’s access as a route into other systems. Narrow authorization boundaries reduce how much a compromised or misdirected agent can affect.

Because agents can act with some autonomy, their behavior may not always match an operator’s intent. Monitoring, constrained permissions, and human approval for consequential actions help limit the impact when an agent behaves unexpectedly.

Accountability gaps
If actions cannot be tied to a distinct identity and an authorization record, it can be difficult to determine what happened and who or what was responsible. Logging and attributable identities make investigation and auditing more practical.

NIST is developing practical guidance rather than presenting a finalized, universal identity standard for agents. On February 5, 2026, its NCCoE published a concept paper proposing a project to apply identity standards and best practices to software agents, including agentic AI applications. The paper invited public comment through April 2, 2026.
On February 17, 2026, NIST’s Center for AI Standards and Innovation announced an AI Agent Standards Initiative covering industry-led standards and protocols, open-source protocol development, and research in agent security and identity. NIST’s project page describes work to identify, manage, and authorize agent access and actions, and to provide implementation guidance; it labels the project status “Soliciting Comments.” These efforts show that the field is developing, not that one settled standard already answers every implementation question.
Until agent-specific guidance matures, organizations can apply existing risk-management and identity practices while following this standards work. NIST’s NCCoE resource hub and CISA’s joint guidance provide current direction on identity, authorization, governance, and oversight.
