Implement zero trust by protecting individual resources and making explicit, identity-aware access decisions—not by treating an internal network, a VPN connection, or enterprise ownership as proof of trust. For AI-enabled environments, bring models, their data, services, dependencies, and supporting hardware and software into the same inventory, identity, access, and risk processes used for other enterprise resources.
What zero trust means for an AI-enabled enterprise
NIST defines zero trust as a set of principles, not a single product or fixed architecture. Its foundational publication, SP 800-207 (2020), shifts the focus from defending a presumed-safe internal network to protecting resources such as data, applications, services, workflows, accounts, devices, and infrastructure. Remote users, personally owned devices, and cloud resources make a single enterprise perimeter an inadequate basis for granting access.
“Zero trust assumes there is no implicit trust granted to assets or user accounts based solely on their physical or network location (i.e., local area networks versus the internet) or based on asset ownership (enterprise or personally owned).”
The statement is from NIST SP 800-207, authored by Scott W. Rose, Oliver Borchert, Stuart Mitchell, and Sean Connelly. In practice, the organization identifies a protected resource, evaluates the subject and device requesting it, and authenticates and authorizes access before establishing a session. Policy should constrain each access relationship to what is needed rather than grant broad reach because a request came from a familiar network.

That principle applies to AI systems without implying that every AI threat has a prescribed zero trust control. NIST’s AI materials describe risks and risk-management approaches; they do not establish a single, finalized end-to-end AI-specific zero trust blueprint. Treat the controls below as an architecture-level application of zero trust principles and AI risk guidance, tailored to the system and its threat model.
What to bring under zero trust governance
Start with the resources and dependencies that support a business process, not just the visible AI application. For an AI-enabled service, that can mean the model and its interfaces, the data used for training or inference, the application that invokes it, the cloud workloads that host it, and the infrastructure and software those workloads depend on.

- Resources: enterprise data, applications, APIs, workflows, devices, cloud workloads, AI models, and their supporting software and hardware.
- Data and flows: training or inference data, model inputs and outputs, and the paths through which data moves between users, applications, services, and models.
- Subjects: people, devices, applications, services, and other nonhuman identities that request access to a resource.
- Ownership and impact: a responsible owner for each important resource, its business purpose, and the impact if its confidentiality, integrity, or availability is compromised.
This inventory is an operational foundation: without it, a policy can protect a front-end application while overlooking a model endpoint, service identity, data store, or dependency that can reach the same sensitive information.
A practical implementation sequence
The following sequence is an implementation approach, not a six-step process mandated by NIST. Adapt it to the organization’s architecture and risk tolerance, and use it to make progress incrementally rather than waiting for a single enterprise-wide redesign.

- Scope resources and business processes. Map important workflows to the data, applications, devices, services, cloud workloads, AI models, model data, and supporting infrastructure they rely on. Record owners and business impact so access policy can reflect what is being protected.
- Map subjects and identities. Identify who and what requests each resource: users, devices, applications, services, and other nonhuman identities. In cloud-native systems, do not rely only on user identity; account for application and service identities as well.
- Define resource-level access policy. Require authentication and authorization before access. Use identity and relevant contextual or device-posture information to decide whether to allow a particular request, and limit permitted access to the task and resource required.
- Select enforcement patterns that fit the environment. Evaluate identity-tier and network-tier policy mechanisms, gateways, proxies, and workload identity options for the applications and infrastructure in scope. Check integration with existing identity, application, and network systems, and account for the skills and operational work required to run them.
- Assess AI risks through the system lifecycle. Use the NIST AI Risk Management Framework (AI RMF) and its Generative AI Profile as risk-management references where applicable. Review assets, data flows, identities, dependencies, and access alongside conventional confidentiality, integrity, and availability risks and AI-specific attack surfaces.
- Monitor, evaluate, and revise. Revisit resource inventories, identities, access decisions, and risk assumptions as systems change. Update the architecture when new dependencies, threats, or authoritative guidance alter the risk picture.
Choosing enforcement patterns for cloud-native systems
Cloud-native and multicloud architectures often need more than network boundaries to express which workloads may communicate. NIST SP 800-207A (final, 2023) describes policy based on application and service identities alongside network parameters and user identities. Its examples include API gateways, sidecar proxies, and application identity infrastructure such as SPIFFE. These are design options, not required components for every deployment.
| Pattern or design dimension | What it can contribute | What to assess |
|---|---|---|
| Identity-tier policy | Policy can distinguish application and service identities as well as users. | Whether identity issuance, lifecycle, and policy integration work across the workloads and environments in scope. |
| Network-tier policy | Network parameters can remain part of access policy and enforcement. | Whether network controls express the resource relationships needed, and how they work alongside identity-based decisions. |
| API gateways and sidecar proxies | These are example enforcement components described in SP 800-207A. | Placement in the request path, integration with applications and policy, and the operational complexity of deployment and ongoing management. |
| Application identity infrastructure, such as SPIFFE | It is an example of infrastructure for application identity in cloud-native designs. | Compatibility with workloads and existing identity systems, and the effort needed to operate identity issuance and enforcement. |
No one row determines the right design. Compare candidate architectures by which identities they govern, how they make and enforce resource-level decisions across on-premises and cloud environments, their fit with existing systems, their observability as risk changes, and the operating complexity and skills they require. NIST’s publications provide implementation examples and architectural dimensions, not a vendor ranking or a universal scoring rubric.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Applying AI risk guidance without overstating it
NIST’s AI Risk Management Framework: Generative Artificial Intelligence Profile (2024) is a cross-sectoral companion to AI RMF 1.0. It describes generative-AI risks and suggested actions organized around the framework’s Govern, Map, Measure, and Manage functions. Use it to structure risk review alongside zero trust architecture guidance: identify the system and its context, map assets and data flows, evaluate risks, and manage them over time.
NIST’s AI security and resilience overview identifies familiar confidentiality, integrity, and availability concerns in AI systems and in training and output data, as well as risks such as evasion, model extraction, membership inference, and availability attacks. It also highlights the complex attack surface created by underlying software and hardware. These concerns support including models, data, services, and infrastructure in enterprise inventory and access reviews. They do not, by themselves, prescribe a one-to-one mapping from each threat to a particular zero trust control.

- For AI-specific attack surfaces, use the system’s context and risk assessment to decide what to monitor and which access relationships need tighter limits.
These are risk-based questions for architecture and review, not controls that NIST has specified as a complete AI zero trust prescription.
Use implementation examples as references, not templates
NIST SP 1800-35 (2025), a practice guide from the National Cybersecurity Center of Excellence, documents example zero trust architecture implementations and lessons. NIST reports that the NCCoE worked with 24 collaborators and integrated commercially available technology to build 19 example implementations. Those counts describe the guide’s project; they are not deployment success rates, market statistics, or proof that any one design fits every organization. Use the examples to compare possible approaches against your own resources, identities, existing infrastructure, and operating capacity.
Keep decisions current as AI guidance evolves
NIST describes AI security as an active research area. Its AI RMF page states that AI RMF 1.0 is being revised and reports that a concept note for a trustworthy-AI-in-critical-infrastructure profile was released on April 7, 2026. A concept note is not a finalized profile. Record the guidance and assumptions used for current decisions, then review them as systems, risks, and authoritative materials change.
