API Governance for Engineering Organizations

How to organize and manage microservice APIs at scale.

Back to API Governance Framework

Compliance Framework Example: Government & Defense (FedRAMP/CMMC)

Context: A technology company providing cloud services to federal agencies and defense contractors must comply with FedRAMP, FISMA, CMMC, ITAR, and NIST security controls. The API governance platform provides the access control enforcement, continuous monitoring, and audit infrastructure that supports compliance with stringent government security requirements.


Platform Scope & Boundaries

What This Platform Provides

The API governance platform is a security enforcement, access control, and continuous monitoring layer that sits between government/defense applications. It provides:

Enforcement Capabilities:

Continuous Monitoring & Audit:

What This Platform Does NOT Provide

The following government/defense-specific capabilities are outside the platform’s scope and must be implemented by backend services or integrated systems:

Security & Intelligence Systems:

Mission-Specific Applications:

Compliance Management:

Integration Model

The platform works in conjunction with these government/defense systems:

The Gateway ensures proper access control based on clearances and classification, captures comprehensive audit trails for continuous monitoring, while backend systems implement mission-specific functionality.


FedRAMP Compliance

FedRAMP (Federal Risk and Authorization Management Program) standardizes security assessment and authorization for cloud services used by federal agencies.

FedRAMP Authorization Levels

Level Use Case Baseline Timeline to ATO
LI-SaaS Low-impact SaaS (public data, no PII) FIPS 199 Low Impact 3-6 months
Low Low-impact systems (limited PII) NIST 800-53 Low Baseline 6-9 months
Moderate Moderate-impact systems (PII, CUI) NIST 800-53 Moderate Baseline 12-18 months
High High-impact systems (law enforcement, emergency services) NIST 800-53 High Baseline 18-24 months

The API governance platform supports FedRAMP Moderate by default, providing the technical controls and evidence required for authorization.

Classification Level Enforcement

Government systems handle data at different classification levels that must not intermingle without proper authorization.

Classification Levels

Level Examples Access Requirements Network Isolation
Unclassified Public data, non-sensitive information Standard authentication Internet-connected
CUI Controlled Unclassified Information (FOUO, LES, SBU) CAC/PIV + MFA, need-to-know Isolated from public internet
Confidential Lowest level of classified information Secret clearance + need-to-know SIPRNET or equivalent
Secret Serious damage to national security if disclosed Secret clearance + need-to-know SIPRNET
Top Secret Exceptionally grave damage if disclosed TS/SCI clearance + need-to-know JWICS
