Six Core Modules

The security-compliance directory is organized into six self-contained modules. Each one implements a specific domain of federal security requirements with production-ready code, configuration, and tests.

Multi-Classification Framework

Bell-LaPadula enforcement across NIPR, SIPR, and JWICS networks. ML-based content classification at <50ms latency with intelligent caching and real-time data spillage detection. Cross-domain guard simulation for development environments.

35ms avg · 98.5% SLA · 87% cache hit rate

CAC/PIV + OAuth 2.0 Authentication

Chained smart card authentication to OAuth PKCE across Advana, Databricks, Qlik, and Navy Jupiter. PKCS#11 middleware abstraction supporting ActivClient, OpenSC, CoolKey, and CACKey. AES-256-GCM token encryption at rest.

84 files · 4 platform adapters

RBAC + ABAC Access Control

Combined MAC, DAC, RBAC, and ABAC with DENY-first logic. PostgreSQL-backed with <100ms decisions at 1,000+ authorizations per second. JSON policy language for attribute-based rules with emergency access override procedures.

<100ms decisions · 1000+ authz/sec

Automated Compliance Documentation

Generates System Security Plans (SSP), Security Assessment Reports (SAR), and Risk Assessment Reports (RAR) from live system data. Jinja2 templating with multi-format output: HTML, PDF, DOCX, and Markdown.

Tamper-Proof Audit System

Blockchain-inspired hash chaining with SHA-256, Merkle tree verification, and RSA-4096 digital signatures. WORM-compliant storage with 7-year retention. MITRE ATT&CK framework integration for threat detection.

100K events/sec · 7-year retention

Security Testing Pipeline

SAST across 8 languages, DAST for web applications and APIs. CVSS 3.1 + EPSS vulnerability scoring with CI/CD quality gates and automated remediation planning.

8 languages · CVSS 3.1 + EPSS

How It Connects

The six modules form a pipeline. A user authenticates via CAC/PIV, receives an encrypted OAuth token, and every subsequent request passes through RBAC/ABAC authorization. Data access is gated by the multi-classification framework, and every decision is recorded in the tamper-proof audit trail.

graph LR A["CAC/PIV Auth"] --> B["Token Manager"] B --> C["RBAC / ABAC"] C --> D["Multi-Classification"] D --> E["Audit Trail"] E --> F["Compliance Reports"]

End-to-end security pipeline. Authentication feeds authorization, which gates classified data access. Every decision is audited and feeds compliance reporting.

Explore the Code

Performance benchmarks: Classification at 35ms average (50ms SLA), RBAC decisions under 100ms at 1,000+ authorizations per second, audit ingestion at 100,000 events per second with sub-50ms write latency. All figures from the validation suites included in each module.

The full implementation is open source. Each module includes its own README, configuration examples, test suites, and deployment instructions.
