Introduction

For agencies handling Criminal Justice Information (CJI), compliance with the CJIS Security Policy is non-negotiable. Logging, audit trails, and audit readiness are central to proving that access, retention, and security controls are functioning as intended. This blog explores how organizations can implement CJIS-compliant logging and audit practices to ensure compliance, defensibility, and operational integrity.

Logging Requirements

Logging ensures that every interaction with CJI is tracked, immutable, and reviewable.

Key CJIS Requirements:

  • Record user access events, including successful and failed login attempts.
  • Log all create, read, update, and delete (CRUD) actions against CJI.
  • Capture system-level events such as configuration changes and policy enforcement.
  • Ensure logs are immutable, tamper-proof, and retained for the required duration.

Audit Trails

Audit trails provide the chronological record of all events related to CJI archives, enabling transparency and defensibility.

Core Elements:

  • Immutability: Logs must be unalterable to preserve trust.
  • Detail: Capture timestamps, user IDs, IP addresses, and actions.
  • Chain of Custody: Demonstrate continuity and integrity of evidence.
  • Monitoring: Regular reviews of audit trails to detect anomalies.

Benefits:

  • Supports investigations of insider threats or external breaches.
  • Provides proof of compliance during audits.
  • Increases confidence in archive defensibility.

Audit Readiness

Being audit-ready means more than storing logs—it requires preparation and structured processes.

Best Practices:

  1. Centralize Logs: Use SIEM or centralized log management systems for visibility.
  2. Automate Alerts: Trigger alerts for suspicious activities (e.g., mass exports, failed login spikes).
  3. Retention Compliance: Retain logs per CJIS retention requirements.
  4. Mock Audits: Conduct regular internal audits to validate readiness.
  5. Documentation: Maintain clear policies, procedures, and mappings to CJIS controls.

Mapping to CJIS Security Policy

  • Section 5.4 (Audit and Accountability): Defines what must be logged and retained.
  • Section 5.10 (Cryptographic Controls): Requires protecting logs with encryption.
  • Section 5.6 (Incident Response): Logs play a central role in breach investigations.

Conclusion

Logging and audit trails are the backbone of CJIS-compliant archiving. By ensuring immutability, completeness, and audit readiness, agencies can strengthen compliance, defend against breaches, and demonstrate trustworthiness in handling CJI.
