Identity Governance and Administration (IGA) is the discipline of managing who has access to what, for how long, and under what conditions — across all users, roles, systems, and data. In government cloud environments, identity governance is not optional or supplementary; it is the operational core of zero trust architecture and the mechanism by which NIST 800-53 Access Control (AC) and Identification and Authentication (IA) control families are implemented.
The Identity Governance Problem in Government Programs
Government programs managing cloud environments face specific identity challenges that commercial programs often don't encounter at the same scale:
Population diversity: A single program may serve contractors from multiple companies, federal employees, military service members, and system accounts — each with different credential requirements, background check levels, and access entitlement rules.
Clearance-level segregation: Access to specific system compartments must be restricted to individuals with appropriate clearances and need-to-know. Manually managing these entitlements across hundreds of users and dozens of systems is error-prone without an automated IGA system.
Contractor lifecycle velocity: On large government contracts, personnel change frequently — new hires require immediate access provisioning; departing personnel require immediate revocation. Manual offboarding is a documented security failure mode across multiple government breach post-mortems.
Audit evidence requirements: Continuous Monitoring (ConMon) under FedRAMP and the CDM program requires documented evidence of access reviews, privileged account management, and anomalous access detection. IGA systems generate this evidence automatically.
Identity Governance and Administration (IGA) Systems
IGA platforms — SailPoint, Saviynt, Microsoft Identity Governance, and others — provide:
Access request and approval workflows: Users request access to systems; approvals route through designated approvers; approved access is provisioned automatically; requests are logged with full audit trail.
Role-based access control (RBAC) management: Access entitlements are bundled into roles that align with job function, clearance level, or program assignment. Role definitions are managed centrally rather than granting individual entitlements per system.
Access certification campaigns: Periodic reviews (often quarterly per FedRAMP requirements) where system owners and managers certify that each user's access is still appropriate. Certified access is retained; uncertified access is revoked. IGA systems automate the workflow and generate compliant documentation.
Segregation of Duties (SoD) enforcement: Preventing users from holding conflicting access rights — for example, a user who both creates financial transactions and approves them. SoD rules are defined once and enforced automatically at provisioning time.
Privileged Access Management (PAM)
Privileged accounts — system administrators, database administrators, root accounts, and service accounts with elevated permissions — are the primary target in most government system breaches. PAM solutions address privileged account risk through:
Privileged account discovery: Automated scanning to identify all privileged accounts across the environment, including service accounts and local administrator accounts that may have been created outside normal provisioning processes.
Just-in-time access: Privileged access is granted for specific time windows rather than persistently — a system admin receives elevated access for the duration of a specific maintenance task, and access expires automatically. This approach dramatically reduces the blast radius of compromised credentials.
Session recording and monitoring: All privileged sessions are recorded (screen capture and keylogging for command-line access) and monitored for anomalous behavior. Session recordings satisfy NIST 800-53 AU (Audit and Accountability) control requirements.
Secrets and credential vaulting: Service account passwords, API keys, SSH keys, and database credentials are stored in a secure vault (HashiCorp Vault, CyberArk, AWS Secrets Manager). Applications retrieve credentials programmatically rather than storing them in code or configuration files.
Zero Trust and Identity
CISA's Zero Trust Maturity Model positions identity as one of five core pillars — the assertion that "identity is the new perimeter" is particularly relevant in government cloud environments where the traditional network perimeter (controlled by firewalls) no longer contains all resources or users.
Zero trust identity principles for government programs:
Multi-Factor Authentication everywhere: MFA is required for all users accessing government systems — FIDO2/WebAuthn or PIV/CAC card authentication is the federal standard. Software TOTP (authenticator apps) may be acceptable in some contexts; SMS is not acceptable for sensitive government systems.
Continuous authentication and risk-based access: Rather than authenticating once and trusting a session indefinitely, zero trust architectures reauthenticate based on risk signals — unusual geographic access, new device, high-privilege action. Conditional access policies in Microsoft Entra ID or Okta implement this model.
Least-privilege access: Access grants are as narrow as technically possible — read access rather than write access unless write is required; access to specific S3 prefixes rather than entire buckets; time-bounded access rather than permanent grants.
Machine identity management: Service-to-service API calls in microservices architectures require strong machine identity — SPIFFE/SPIRE, AWS IAM Roles for Service Accounts (IRSA), or short-lived token exchange. Hardcoded credentials in application code are the most common exploitable vulnerability in modern cloud systems.
FedRAMP Control Coverage for IGA
An IGA system addresses a substantial subset of FedRAMP's AC and IA control families: - AC-2 (Account Management): Automated provisioning/deprovisioning, user account review, account type segregation - AC-5/AC-6 (Separation of Duties / Least Privilege): SoD enforcement, RBAC management - AC-17 (Remote Access): PAM session recording for privileged remote access - IA-2 (Identification and Authentication): MFA enforcement documentation - IA-4/IA-5 (Identifier Management / Authenticator Management): Account lifecycle documentation - AU-6 (Audit Review): Access certification evidence generation

Frequently Asked Questions
What is the difference between IAM and IGA?
IAM (Identity and Access Management) refers to the technical systems that enforce authentication and authorization — AWS IAM, Azure AD, Okta. IGA (Identity Governance and Administration) refers to the governance layer on top — the workflows, certifications, SoD rules, and audit evidence generation that ensure access is appropriate, compliant, and auditable. Both are necessary; IGA without IAM has nothing to govern, and IAM without IGA lacks the business process controls that compliance frameworks require.
What PAM solution is recommended for federal programs?
CyberArk is the market leader with the strongest government and FedRAMP authorized offering. HashiCorp Vault (now part of HashiCorp Cloud Platform) is widely used for secrets management and machine identity. Delinea (formerly Thycotic/Centrify) and BeyondTrust are also FedRAMP authorized alternatives. Selection depends on whether the primary use case is human privileged access management, machine secrets management, or both.
How does PIV/CAC authentication integrate with cloud IAM?
Federal employees use PIV (Personal Identity Verification) smart cards and military personnel use CAC (Common Access Card) for authentication. These are X.509 certificate-based credentials that integrate with cloud IAM through SAML 2.0 federation from an agency identity provider (Active Directory Federation Services, AWS IAM Identity Center, or similar). The cloud IDP accepts the PIV/CAC assertion and maps it to cloud roles. Integration patterns and technical details vary by cloud provider.
Is SailPoint FedRAMP authorized for government programs?
SailPoint IdentityNow has achieved FedRAMP authorization. Saviynt Cloud PAM also has FedRAMP authorization. Before selecting an IGA vendor for a government program, verify current FedRAMP authorization status in the FedRAMP marketplace at marketplace.fedramp.gov — authorization status can change and the marketplace reflects current authorizations.
