Summary

Complete HIPAA Security Rule compliance implementation for vcf-pg-loader, adding comprehensive security controls for handling Protected Health Information (PHI) in clinical genomics workflows.

Changes

Security Infrastructure

  • Secrets Management (src/vcf_pg_loader/secrets.py): Secure credential handling with environment variable support, preventing password exposure in URLs/logs
  • TLS Enforcement (src/vcf_pg_loader/tls.py): TLS 1.2+ required for all database connections with certificate validation (HIPAA 164.312(e)(1))

Audit Logging (HIPAA 164.312(b))

  • Audit Schema (src/vcf_pg_loader/audit/): Partitioned audit tables with 6-year retention
  • Immutability Triggers: Prevents modification/deletion of audit records
  • Hash Chain Integrity: Cryptographic verification of audit log tampering
  • CLI Commands: vcf-pg-loader audit verify, audit export, audit stats

Authentication & Access Control

  • User Management (src/vcf_pg_loader/auth/): User authentication with bcrypt password hashing (HIPAA 164.312(d))
  • Role-Based Access Control: Hierarchical roles with granular permissions (HIPAA 164.312(a)(1))
  • Session Management: Configurable timeouts with automatic logoff (HIPAA 164.312(a)(2)(iii))
  • CLI Commands: vcf-pg-loader auth, roles, permissions, session

PHI Protection

  • PHI Detection (src/vcf_pg_loader/phi/): Pattern-based detection of SSN, MRN, names, dates, addresses
  • Header Sanitization: Automatic removal of PHI from VCF headers during parsing
  • Anonymization: k-anonymity and date generalization for de-identification (HIPAA 164.514(b))
  • CLI Commands: vcf-pg-loader phi detect, phi anonymize, phi patterns

Data Security

  • Encryption at Rest (src/vcf_pg_loader/data/encryption.py): AES-256-GCM for sensitive fields (HIPAA 164.312(a)(2)(iv))
  • Secure Disposal (src/vcf_pg_loader/data/disposal.py): Two-person authorization, certificate of destruction (HIPAA 164.530(j))
  • CLI Commands: vcf-pg-loader security, data dispose, data retention-report

Compliance Validation

  • Compliance Checker (src/vcf_pg_loader/compliance/): Automated validation of all HIPAA controls
  • Report Generation: JSON/HTML/text reports for compliance documentation
  • CI Integration: GitHub Actions workflow for continuous compliance checking
  • CLI Commands: vcf-pg-loader compliance check, compliance report, compliance status

Container Security

  • Docker Hardening (src/vcf_pg_loader/doctor.py): Non-root user, read-only filesystem, dropped capabilities checks

New CLI Commands

Command Description HIPAA Reference
compliance check Run all compliance checks -
compliance report Generate compliance report -
compliance status Quick compliance summary -
audit verify Verify audit log integrity 164.312(b)
audit export Export audit logs 164.312(b)
auth create-user Create authenticated user 164.312(d)
session list List active sessions 164.312(a)(2)(iii)
roles create Create RBAC role 164.312(a)(1)
phi detect Scan for PHI 164.514(b)
phi anonymize De-identify data 164.514(b)
security init Initialize encryption 164.312(a)(2)(iv)
data dispose Secure data disposal 164.530(j)

Test Coverage

  • 76 new unit tests for compliance module
  • Integration tests with PostgreSQL containers
  • Tests for audit immutability, TLS, RBAC, session management
  • PHI detection and anonymization tests

Files Changed

  • 84 files changed, ~22,000 lines added
  • New modules: audit/, auth/, phi/, data/, compliance/
  • New workflows: compliance-check.yml

Implements automated compliance validation with TDD approach:
- ComplianceValidator checks TLS, audit, auth, RBAC, encryption, sessions
- CLI commands: compliance check, report, status
- JSON/HTML/text report export formats
- Exit codes reflect compliance status for CI/CD integration

This seems to adequately get the project to HIPAA compliance, or at least close enough so that when real PHI passes through these tools, the bulk of the work (>95% time coding) should be complete.
