DTM 25-003 User Pillar: Enterprise Attribute Standardization Is the First Gate Your DoD ZTA CoA Scorecard Has to Clear
Conditional user access fails when the enforcement point cannot trust the user attribute feeding the decision. For DoD program offices, that is not an ICAM housekeeping issue. It is the first gate in the User Pillar that determines whether downstream Zero Trust controls are operating on verified enterprise data or local assumptions. Under DTM 25-003, the question is direct:
Have you established a basic set of user attributes for authentication and authorization across the enterprise?
That sounds basic until a program office tries to answer it across mission systems, privileged accounts, contractor populations, federated identities, legacy applications, and disconnected attribute stores. Most programs do not fail here because they lack an identity provider. They fail because user attributes are inconsistent, stale, locally defined, or not mapped to real authorization decisions.
AISE addresses this problem by assessing the control once and producing two separate outputs: a DoD ZTA CoA maturity score and a CISA ZTMM score. For DoD program offices, that means a clean CoA scorecard aligned to DTM 25-003, DoD Zero Trust Strategy, DoD ZTA CoA, and NSA ZIG without mixing civilian framework language into the program decision package.
Why DTM 25-003 makes user attributes a control gate
DTM 25-003 moves Zero Trust implementation from concept to execution. For the User Pillar, conditional access decisions must be grounded in verified, enterprise-wide user attributes. The DoD Zero Trust Strategy and DoD ZTA CoA reinforce the same point: access decisions cannot depend only on network location, static role assignments, or application-specific group logic.
NSA Zero Trust guidance is equally clear on the identity principle. Attribute-based access control only works when attributes come from authoritative enterprise sources and are updated through controlled life-cycle processes. If the enforcement point receives conflicting values from multiple stores, the policy engine may still make a decision, but the program cannot rely on that decision as a mature Zero Trust control.
This is why enterprise attribute standardization sits at the beginning of conditional user access. Before a program office can mature privileged access, dynamic policy, just-in-time access, or application owner self-service, it has to answer a more basic question: what user attributes are trusted across the enterprise, where do they come from, and how are they maintained?
The strategic diagnostic: What the User Pillar is really asking
The anchor activity for this capability asks whether the organization has established a basic set of user attributes for authentication and authorization across the enterprise. At Strategic Foundation level, this is not a tooling inventory. It is a governance and mission-risk question.
A program director or CISO staff lead should be able to identify the enterprise attributes that drive access decisions: user identity, affiliation, role, organization, clearance or eligibility indicators where applicable, privileged status, mission assignment, device or session context dependencies, and other attributes approved for authorization use. Those attributes must be defined consistently enough that enforcement points interpret them the same way.
The supporting activities expose whether that foundation is real. Are enterprise roles and authorization attributes registered in the ICAM system? Are they integrated with identity life-cycle management? Has privileged access moved into a dedicated PAM solution? Is there a standard process for updating roles and attributes? Are all privileged users managed through PAM? Can application owners register or consume enterprise attributes through a self-service model rather than creating local substitutes?
Those are not separate checklist items. They form one operating model. If roles are not registered in ICAM, applications create their own. If attributes are not tied to life-cycle management, access decisions lag behind personnel changes. If privileged access is not exclusively managed through PAM, elevated rights remain outside the conditional access model. If application owners cannot consume approved enterprise attributes, they rebuild authorization logic locally. Each gap weakens the DoD ZTA CoA maturity score because each gap breaks the chain of trusted user context.
What AISE maturity levels mean in practical terms
AISE scores this capability against the DoD ZTA CoA and separately against the CISA ZTMM from the same assessment. The DoD program office sees its CoA position clearly, while the separate ZTMM output remains available for enterprise reporting or cross-agency comparison when needed.
Maturity Level 1: Local assumptions drive access
At Level 1, the program has identity data, but not a trusted enterprise attribute model. Applications maintain their own groups. Privileged access may be documented but not fully enforced through PAM. Attribute updates depend on tickets, manual changes, or system-specific administrators. Conditional access policies exist in pockets, but they rely on inconsistent user data.
This is the common state for programs with legacy mission systems and multiple integrator-managed environments. The problem is not lack of effort. The problem is that scarce staff time is spent reconciling identities instead of advancing Zero Trust implementation.
Maturity Level 3: Enterprise attributes support repeatable decisions
At Level 3, the program has defined authoritative sources for core user attributes. ICAM contains registered roles and authorization attributes. Identity life-cycle management updates those attributes through a repeatable process. PAM is the standard path for privileged activities, and privileged users are increasingly managed through that dedicated solution. Application owners consume approved attributes rather than inventing local copies.
This level changes the conversation. The program can show how conditional user access decisions are made, which attributes are used, where those attributes originate, and how they are updated. That supports DTM 25-003 implementation and gives ZT leads a defensible roadmap for the next maturity step.
Maturity Level 5: Real-time verified attributes drive enforcement
At Level 5, attribute management is not a periodic cleanup process. Enterprise attributes are verified, current, and available to enforcement points in near real time. Privileged access is managed exclusively through the PAM model. Application owners can register new attribute needs or consume existing enterprise attributes through governed self-service. Policy engines can make conditional access decisions using trusted identity context across mission and enterprise environments.
This is where conditional user access becomes a dependable Zero Trust control rather than a static identity administration function.
Progression tracking: Turning the score into milestones
A maturity score only helps if it drives execution. AISE turns the assessment into a progression tracker by separating the work into scoped milestones that program offices can align to PPBE cycles, ATO pressure, and integrator work packages.
Define the enterprise user attribute baseline for authentication and authorization.
Identify authoritative sources for each attribute and eliminate conflicting local definitions.
Register enterprise roles and authorization attributes in ICAM.
Connect attribute updates to identity life-cycle events such as onboarding, transfer, separation, role change, and privilege elevation.
Migrate privileged access workflows into a dedicated PAM solution.
Require privileged users to operate through PAM rather than exception-based local administration.
Enable application owners to request or consume approved attributes through a governed registration process.
This is where automated assessment matters. Manual Zero Trust assessments take too long and consume too much staff time, especially when program offices are operating under continuing resolution uncertainty, constrained billets, and competing modernization demands. AISE compresses the assessment cycle by 50 percent using the DoD framework and CISA ZTMM in one assessment, then separates the outputs so the DoD CoA score remains clean.
ROM timelines for moving the User Pillar forward
Realistic timelines depend on mission-system complexity, inherited environments, and how fragmented the current ICAM and PAM landscape is. For planning purposes, most DoD program offices can structure progression this way.
From Level 1 to Level 2, plan for 30 to 60 days to inventory user attributes, identify authoritative sources, document current role and privilege models, and establish the first enterprise attribute baseline. This phase is about visibility. Many agencies are flying blind on actual Zero Trust maturity because they lack a common measurement model.
From Level 2 to Level 3, plan for 90 to 180 days to register roles and attributes in ICAM, connect attributes to identity life-cycle processes, and formalize update workflows. PAM migration planning usually begins here, with priority on administrators, system owners, and mission-critical privileged groups.
From Level 3 to Level 4, plan for 6 to 12 months to expand PAM coverage, reduce local authorization stores, integrate application owners into the approved attribute model, and validate that enforcement points consume enterprise attributes consistently.
From Level 4 to Level 5, plan for 12 to 24 months depending on architecture. This phase requires deeper automation, near-real-time attribute refresh, stronger policy integration, and broader mission-system participation. The work is achievable, but it must be managed
as a program progression plan, not a one-time assessment.
A federal scenario: the defense logistics pattern
In a DLA-style logistics environment, user populations often span government civilians, uniformed personnel, support contractors, warehouse operations, application administrators, and mission partners. Different systems may define role, location, organization, and privilege in different ways. One application may treat a contractor as a mission user, another as a support role, and another as a local group member with elevated rights.
The Zero Trust issue appears when conditional access policy needs to make a decision across that environment. If the program cannot determine which attribute is authoritative, the enforcement point becomes dependent on application-local logic. That slows ATO conversations, complicates remediation planning, and makes it harder for program leadership to explain progress against DTM 25-003.
The mature pattern is to define the enterprise user attribute baseline, register the roles and attributes in ICAM, tie updates to life-cycle events, place privileged activity under PAM, and give application owners a governed path to consume enterprise attributes. That does not remove mission complexity. It gives the program a common control fabric for conditional user access.
One assessment. Two scorecards. No framework noise.
DoD program offices do not need another generic Zero Trust slide deck. They need to know where they stand against the DoD ZTA CoA, what DTM 25-003 implementation gaps are blocking maturity, and which milestones should be funded and executed next.
AISE was built for that operating reality. It produces a DoD ZTA CoA maturity score and a separate CISA ZTMM score from a single assessment. The CoA view stays focused on the DoD mandate, while the ZTMM view remains available for broader reporting. Zephon has done this work inside real federal environments, including IRS and DLA. This is not theoretical consulting language.
