UIAO Modernization Atlas

Identity-Driven Infrastructure for FedRAMP Moderate Environments

Published

April 4, 2026

1 The Problem

Federal agencies operating FedRAMP Moderate environments contend with fragmented identity systems, manual compliance evidence collection, and no cross-service telemetry. Legacy ICAM, network, and compliance tools operate as independent silos — each authoritative within its domain, none aware of the others. When an identity event occurs — a joiner, mover, or leaver — there is no deterministic way to trace its effects across all dependent systems in real time.

The consequence is twofold: security gaps widen between identity events and their downstream enforcement, and compliance evidence remains point-in-time rather than continuous.


2 The Solution

The Unified Identity-Addressing-Overlay Architecture (UIAO) is a drop-in overlay that restores cross-service telemetry and identity correlation in FedRAMP Moderate environments where native platforms cannot. UIAO sits atop existing vendor stacks — Azure Active Directory, Cisco ISE, Palo Alto Networks, Infoblox, Microsoft Sentinel — and provides deterministic identity-to-addressing correlation, real-time drift detection, and OSCAL-native compliance automation. No rip-and-replace of existing infrastructure is required. Existing authorizations, integrations, and tooling are preserved; UIAO adds the correlation layer they lack.


3 Key Outcomes

Outcome Description
Leaver Killswitch: <120 seconds An identity termination event propagates to network enforcement (ISE policy, DNS/DHCP revocation, SD-WAN segmentation) within two minutes, deterministically.
Continuous Compliance Evidence Control satisfaction is captured at event time, not assembled at audit time. OSCAL artifacts reflect current posture rather than a snapshot.
Cross-Service Telemetry Correlation Identity events, network state changes, and security signals are correlated in a single data model. No manual log correlation required.
OSCAL-Native SSP and POA&M System Security Plans and Plans of Action and Milestones are generated directly from the UIAO canon. FedRAMP 20x machine-readable submission is supported natively.

4 Six Control Planes

UIAO is organized as six discrete control planes. Each plane owns a specific operational domain; together they form a closed-loop system where identity state drives all downstream enforcement and compliance reporting.

Six control planes: Identity, Addressing, Overlay, Telemetry, Management, Governance, shown as a left-to-right flow.

5 Who This Is For

This Atlas is written for federal technical and compliance practitioners who own or assess FedRAMP Moderate system authorizations:

  • Federal CISOs and CIOs evaluating identity-driven zero trust architecture
  • FedRAMP Assessors (3PAOs) reviewing continuous monitoring posture and control implementation
  • Compliance Officers responsible for SSP currency, POA&M management, and audit evidence
  • IT Modernization Program Managers replacing legacy ICAM, DDI, and network segmentation infrastructure
  • Security Architects designing zero trust network access in hybrid cloud environments
