CISA ZTMM User Pillar: Building Dynamic Privilege Rules for OMB M-22-09 Identity Requirements

Dynamic Privilege Control Require Real-time Context Knowledge

Most civilian agencies still have a privilege problem hiding inside normal operations: static Active Directory groups, standing administrator roles, VPN-era access assumptions, and quarterly access reviews that do not respond to user risk in the moment. That model does not hold up against the CISA Zero Trust Maturity Model User Pillar or the identity direction in OMB M-22-09. Conditional user access has to move from policy language into enforceable rules that can enable, limit, or remove privileges based on authentication context, device posture, session risk, and mission need.

What OMB M-22-09 and CISA ZTMM Require for Conditional User Access

OMB M-22-09 Section III.B pushed civilian agencies toward identity-centric Zero Trust, including strong authentication, periodic re-authentication, least privilege, and conditional access policies. The point is not another annual review cycle. The point is dynamic enforcement: users receive the minimum access required, for the period required, under conditions that can be evaluated and changed.

CISA ZTMM makes this practical through the User Pillar. At Traditional maturity, agencies usually rely on static accounts, static groups, and manual reviews. At Initial and Advanced maturity, access decisions begin using real-time signals, stronger authentication events, device trust, and risk indicators. At Optimal maturity, agencies are applying continuous validation and dynamic privilege adjustment at the session or transaction level.

FISMA reinforces the same operating model through continuous monitoring and ongoing authorization expectations under NIST SP 800-37 and NIST SP 800-53 access control and assessment controls. FedRAMP Moderate and High baselines also matter here because many agencies now enforce identity controls through FedRAMP-authorized cloud platforms. If conditional access is only applied to headquarters applications and not cloud workloads, the agency does not have a consistent User Pillar implementation.

The policy direction is clear: civilian agencies need to move away from standing privilege and toward rules that respond to authentication, authorization, risk, and context. The challenge is doing that while operating under continuing resolution uncertainty, lean IT staffing, inherited application portfolios, and procurement timelines that often lag mission demand.

The Diagnostic Question That Exposes the Real Maturity Level

The anchor question for this capability is direct: does the organization use rules from the periodic authentication process to dynamically enable or disable user privileges? That single question separates a written access policy from an implemented access control.

In practice, we look for evidence that re-authentication is not just a prompt on a schedule. It should feed access decisions. A privileged user who re-authenticates from a managed device on a normal network path may receive one set of permissions. The same user from an unmanaged device, impossible travel pattern, unfamiliar location, or elevated risk session should receive a different outcome: step-up authentication, reduced privilege, just-in-time approval, session recording, or denial.

The supporting questions matter because they expose whether dynamic access is operational or aspirational. Administrative users should be moving toward Just-in-Time and Just-Enough-Access permissions for applications and services. Use of JIT and JEA should be logged and monitored for security operations, FISMA reporting, and management visibility. Dynamic privilege rules should be tested regularly to confirm they limit access to application functions and data as intended. Applications should be evaluated and configured to support JIT and JEA, not exempted indefinitely because they are difficult.

There is also a process architecture question agencies need to face with discipline: are dynamic access decisions integrated with AI or machine learning, and does rule-based access support automated rule management? AI and ML are not the starting point. They are not a substitute for clean identity data, application mapping, or tested policy logic. But at higher maturity, agencies need automation that can identify abnormal access patterns, recommend rule changes, and support faster risk-based decisions without adding manual burden to already stretched teams.

What the AISE Maturity Score Means in Practice

AISE, Zephon LLC's Assess, Identify, Strategize, Execute Zero Trust Maturity & Governance Platform, evaluates this capability once and produces separate maturity scores for CISA ZTMM and DoD ZTA CoA. For civilian agencies, the lead output is the CISA ZTMM maturity score mapped to OMB M-22-09 requirements, with the DoD ZTA CoA score available as additional context for agencies that operate alongside defense partners, shared services, or national security mission environments.

One assessment. Two scorecards. Your CISA ZTMM maturity score and your OMB M-22-09 implementation gap stay separate, clean, and ready for leadership reporting.

Maturity Level 1: Static Privilege Still Dominates

At Level 1, the agency usually has MFA in place for priority users, but privilege is still assigned through static groups or standing roles. Access reviews may occur every 90 days or annually, but they do not dynamically change access during a session. Admin accounts may have broad access across systems. Cloud applications may enforce different rules than on-prem systems. Logging may show who signed in, but not whether privilege elevation was appropriate for that session.

Maturity Level 3: Conditional Access Is Enforced for Priority Use Cases

At Level 3, the agency has implemented conditional policies for key applications, privileged accounts, and higher-risk user groups. Periodic authentication events influence access decisions. JIT and JEA are used for administrative functions in priority systems. Device posture and identity risk are included in policy decisions. Logs are available for security operations and reporting. FedRAMP-authorized identity and cloud services are configured to support consistent enforcement across major workloads.

Maturity Level 5: Privilege Adjusts Based on Real-Time Risk

At Level 5, privilege is dynamic by design. Access is evaluated continuously using user behavior, device status, session risk, application sensitivity, and transaction context. Administrative permissions are time-bound, purpose-bound, monitored, and revoked automatically. Dynamic rules are tested, tuned, and governed. AI and ML capabilities support anomaly detection, policy recommendations, and automated rule management, with human oversight where mission risk requires it.

Turning the Score Into Executable Milestones

A maturity score only matters if it drives decisions. For conditional user access, we turn the score into milestones that program managers, CISOs, IT directors, and procurement teams can act on.

• First, identify where standing privilege creates the highest mission and data risk: identity administrators, cloud administrators, financial systems, case management platforms, data analytics environments, and shared service integrations.

• Second, map current authentication events to access decisions. If re-authentication does not change privilege, the control is not yet dynamic.

• Third, define JIT and JEA policy patterns for administrative access. Start with the systems where the business owner and system owner can support change.

• Fourth, validate FedRAMP procurement paths. If the agency is buying identity, PAM, SIEM, SOAR, or cloud access tooling, FedRAMP authorization status and integration capability must be part of acquisition planning.

• Fifth, establish testing and reporting. Dynamic rules need evidence: policy configuration, access logs, exception records, test results, and leadership-level metrics.

This approach respects the reality of civilian IT environments. Agencies cannot replace every application at once. They can sequence access modernization by risk, budget window, contract vehicle, and operational readiness.

ROM Timelines for Moving the Capability Forward

For most civilian agencies, conditional user access improvement falls into three practical time bands.

In 30 to 60 days, an agency can baseline current privilege models, identify priority applications, document where periodic authentication does or does not influence access, and establish the initial CISA ZTMM User Pillar score. This is also where procurement officers can confirm which current tools are already FedRAMP-authorized and which gaps require acquisition planning.

In 90 to 180 days, agencies can implement conditional access policies for priority user populations, reduce standing administrator access, pilot JIT and JEA for selected systems, and begin logging privilege elevation activity in a form security operations can use. This is the realistic window for moving from static policy to operational enforcement in targeted areas.

In 6 to 12 months, agencies can expand dynamic privilege rules across major applications, standardize JIT and JEA patterns, integrate conditional access with cloud workloads, tune risk signals, and build recurring leadership reporting aligned to CISA ZTMM and OMB M-22-09 implementation expectations.

In 12 to 24 months, agencies with complex legacy estates can mature toward broader automation, AI or ML-assisted rule management, continuous validation, and stronger integration with ongoing authorization processes. That timeline is normal for large civilian environments with mixed on-prem, SaaS, shared service, and mission application dependencies.

An Anonymized Civilian Agency Scenario

One civilian agency we supported had MFA deployed and strong executive commitment, but its privilege model was still built around static groups. System administrators retained standing access to multiple applications, quarterly reviews were treated as the primary control, and several FedRAMP cloud services had conditional access configured differently than internal systems.

The first step was not a tool replacement. We built the maturity baseline, mapped privileged access paths, and separated policy intent from actual enforcement. The agency found that periodic authentication was occurring, but it rarely changed user privilege. That explained why the organization looked stronger on paper than it operated in practice.

The implementation path focused on three moves: JIT access for identity and cloud administrators, JEA patterns for selected application support teams, and centralized logging of privilege elevation events. Procurement then used the baseline to prioritize integration requirements for cloud identity and privileged access tooling through FedRAMP-aligned acquisition channels.

Within two quarters, the agency had a defensible leadership view of where conditional user access was working, where static RBAC remained, and which applications needed modernization planning. The outcome was not a slogan about Zero Trust. It was a clearer operating model for reducing standing privilege without overwhelming the security team.

Start With the Baseline

Conditional user access is where the CISA ZTMM User Pillar becomes operational. If periodic authentication does not influence privilege, the agency is still depending on static trust. If JIT and JEA are not logged, tested, and applied to priority systems, leadership does not have the visibility needed to manage risk or show progress against OMB M-22-09 implementation expectations.

AISE gives civilian agencies a practical starting point: a CISA ZTMM maturity score mapped to OMB M-22-09, plus a separate DoD ZTA CoA score for additional context from the same assessment. No duplicate survey. No mixed scoring model. Just a clean baseline that helps leadership decide what to fix first.
