In a bid to fortify the nation’s cybersecurity framework, the United States Cybersecurity and Infrastructure Security Agency (CISA) has unveiled comprehensive guidance on the integration of Identity and Access Management (IDAM) capabilities within Identity, Credential, and Access Management (ICAM) architectures for federal agencies.

This pivotal document, available in PDF format, emerges under the umbrella of CISA’s Continuous Diagnostics and Mitigation (CDM) program, designed to provide Information Security Continuous Monitoring (ISCM) capabilities aimed at bolstering the security of federal network systems.

CISA recognizes the complexity surrounding ICAM deployment across diverse U.S. government agencies, each charting its own course with unique priorities. Further complicating matters are disparities in Identity Management maturity levels among agencies, particularly concerning tool expertise and ICAM-related policies. These variations can impede ongoing CDM integration efforts, potentially leading to incomplete or less effective ICAM implementations.

To tackle this intricate challenge, CISA’s latest guidance offers clarity on the scope of IDAM within the CDM program, delineates CDM’s IDAM capabilities, and defines ICAM practice areas for federal agencies. It also introduces a CDM ICAM reference architecture, a blueprint for establishing a robust and efficient ICAM capability enriched with CDM functionality.

Within the ambit of CDM IDAM capabilities, CISA outlines sub-capabilities such as Privileged Access Management (PAM), Identity Lifecycle Management (ILM), and Mobile Identity Management (MIM). Additionally, the guidance extends its reach to encompass non-person entities (NPE) and other non-Public Key Infrastructure (PKI) authenticators, addressing the spectrum of credential management and authentication.

• PAM centers on the oversight of privileged human and non-person entities, incorporating tools to ensure stringent authentication protocols.
• ILM takes charge of the life cycle management of user identities and their associated privileges.
• MIM is dedicated to enhancing the security of mobile device usage within the federal landscape.

The CDM ICAM reference architecture, which includes Federation Services, is instrumental in facilitating the adoption of Zero Trust Architecture (ZTA), a paradigm that emphasizes continuous verification of entities, whether inside or outside the perimeter.

This guidance doesn’t stop at theory; it also furnishes insights into a notional CDM ICAM physical architecture, outlines key challenges that CDM ICAM encounters, elucidates how ICAM use cases translate into service components, and offers a series of recommendations for federal agencies keen on advancing the Identity Pillar of a Zero Trust Architecture.

Federal agencies are encouraged to diligently review CISA’s latest guidance, leveraging it as a blueprint to enhance their ICAM capabilities, thereby contributing to a more robust and secure federal cybersecurity landscape.
