DoD Zero Trust Reference Architecture v2.0

Why it Matters

The DoD Zero Trust Reference Architecture v2.0 establishes a robustfoundation to strengthen information security and reduce risk indefense-related environments.

Key benefits include:

• Strengthen cybersecurity governance

Promoteconsistent policy enforcement and continuous verification to ensureeffective security oversight across users, devices, and applications.

• Enhance regulatory alignment

Supportcompliance with federal mandates by aligning security practices withDoD and NIST requirements across agency operations.

• Improve threat detection capabilities

Enable adaptivemonitoring and authentication to identify abnormal behavior andmitigate security incidents before significant damage occurs.

• Increase audit readiness

Simplify thedemonstration of security controls and incident response processes toauditors and regulatory bodies with integrated logging and reporting.

• Promote operational resilience

Reduceoperational risk and maintain mission continuity by enforcing leastprivilege and rapidly containing potential threats within segmentednetwork zones.

How it Works

The DoD Zero Trust Reference Architecture v2.0 structures itsapproach around seven core pillars: users, devices, applications andworkloads, data, network/environment, automation and orchestration,and visibility and analytics. Each pillar encompasses specificcapabilities, requirements, and safeguards, which collectivelyadvance the Zero Trust maturity model. The framework integrates riskmanagement practices, access control mechanisms, and continuousmonitoring functions to ensure that no user or device is implicitlytrusted, regardless of network location.

In practice, organizations implement the DoD Zero Trust ReferenceArchitecture by deploying granular security controls aligned to eachpillar. This involves conducting risk assessments, segmentingnetworks, enforcing least-privilege access, and continuouslyvalidating authentication and authorization. Security and complianceprograms leverage the framework to map regulatory requirements,monitor security posture, and establish clear governance forinformation sharing and incident response.

SmartSuite enables organizations to operationalize the DoD Zero TrustReference Architecture by utilizing integrated control libraries foreach pillar, maintaining risk registers, and managing policygovernance. Features such as evidence collection, compliancetracking, and automated remediation workflows support auditreadiness, while reporting dashboards provide ongoing monitoring andvisibility into Zero Trust adoption and effectiveness.

Key Elements

• Zero Trust Pillars

Structures thearchitecture into distinct security domains such as identity, device,network, application, data, and visibility.

• Policy Decision and Enforcement

Describesmechanisms responsible for making and enforcing access controldecisions based on contextual information.

• Continuous Authentication and Authorization

Specifies therequirement for ongoing validation of user and device identitythroughout every session.

• Asset and Resource Segmentation

Organizes systemsand data into segments to limit lateral movement and exposure withinthe environment.

• Telemetry and Analytics Integration

Outlines theincorporation of monitoring, logging, and analytic capabilities forrisk assessment and incident response.

• Automation and Orchestration Layer

Defines processesand tools that automate security actions and governance acrossdistributed systems.

• Alignment with Federal Mandates

Establishesstructure for compliance with NIST and DoD cybersecurity policies andguidelines.

Framework Scope

DoD Zero Trust Reference Architecture v2.0 is adopted by defenseagencies, military contractors, and federal partners responsible forsafeguarding classified and mission-critical information systems. Itgoverns access controls, network segmentation, and identitymanagement across secure environments, and is typically integratedwhen addressing federal mandates or improving risk management andoperational resilience.

Framework Objectives

DoD Zero Trust Reference Architecture v2.0 establishes acybersecurity model designed to minimize risk and enforce continuoustrust verification.

Enhance data protection by verifying identities and monitoring accessto information

Strengthen cybersecurity governance through unified security controlsand policies

Reduce risk exposure across networks, users, and connected devices

Support compliance with federal cybersecurity and risk managementrequirements

Improve operational resilience through continuous threat detectionand response

Enable audit readiness by documenting and enforcing security controlsand processes The DoD Zero Trust Reference Architecture v2.0 alignsclosely with NIST SP 800-207, CISA Zero Trust Maturity Model, andincorporates guidance from DISA STIGs. Organizations typicallyimplement this framework to strengthen operational security, achieveregulatory compliance, or advance their zero trust posture withindefense and federal environments.
