Audit Logs

Immutable, time-stamped records of all activities and changes within an identity system for compliance and forensics.

What is Audit Logs?

Audit logs are comprehensive, immutable records of all activities and changes within an identity system. They capture who (user ID, IP address), what (action performed), when (timestamp), where (IP, device), and result (success/failure). Audit logs are critical for compliance (SOC 2, ISO 27001, HIPAA, PCI DSS), security incident investigation, forensic analysis, and troubleshooting. Modern CIAM platforms like LoginRadius provide structured audit logs in JSON format, real-time streaming to SIEM tools, and configurable retention policies.

Analogy

Think of audit logs like a black box flight recorder on an airplane. It records every action (who did what, when, and from where) so that if something goes wrong, investigators can reconstruct exactly what happened.

Types and Use Cases

Audit Log Event Types:

  • Authentication: Login, logout, MFA challenge, password reset
  • Authorization: Access granted/denied, role changes, permission updates
  • Administrative: User creation/deletion, policy changes, config updates
  • Data Access: Profile views, PII access, data exports

Common Use Cases:

  • Compliance Reporting: SOC 2, ISO 27001, HIPAA require audit trails
  • Security Investigation: Forensics after a breach or suspicious activity
  • Troubleshooting: Debug why a user can't access a resource
  • Behavioral Analytics: Detect anomalous patterns (impossible travel)

How it Works

1
User or admin performs action (login, profile update, role change); identity system captures event with timestamp, user ID, IP, and outcome
2
Event is structured (JSON format) with relevant metadata (user agent, device, session ID) and written to append-only audit log
3
Logs are indexed for search, retained per compliance policy (1 year for SOC 2, 6 years for HIPAA), and optionally streamed to SIEM tools
terminal
{
  "auditEvent": {
    "eventId": "evt_abc123",
    "timestamp": "2025-03-05T10:30:00Z",
    "eventType": "authentication",
    "action": "login_success",
    "userId": "user_12345",
    "ipAddress": "203.0.113.1",
    "userAgent": "Mozilla/5.0...",
    "sessionId": "sess_xyz789",
    "outcome": "success",
    "metadata": {
      "mfaUsed": true,
      "deviceTrusted": false,
      "loginMethod": "password"
    }
  }
}

Audit Logs vs Debug Logs

Audit Logs
Debug Logs

Audit logs are append-only and tamper-proof for compliance,

debug logs are for troubleshooting and can be modified

Audit logs have strict retention (1-6 years),

debug logs are often rotated/deleted quickly

Audit logs focus on who did what (identity context),

debug logs focus on system behavior

Best Practices for Audit Logs

  • Immutable Storage: Ensure audit logs are append-only, tamper-proof (required for compliance)
  • Structured Format: Use JSON format with consistent fields (timestamp, user, action, outcome) for easy parsing
  • Compliance Retention: Retain logs per regulation (SOC 2: 1 year, HIPAA: 6 years, PCI DSS: 1 year minimum)

How LoginRadius Powers Audit Logs

LoginRadius CIAM platform provides comprehensive audit logging with 40+ event types covering the entire user lifecycle. Our platform offers real-time log streaming via webhooks, historical audit logs with full-text search, configurable retention policies, and out-of-the-box SIEM integrations (Splunk, ELK). LoginRadius also provides pre-built compliance reports and ensures audit logs are append-only and cryptographically secured.

FAQs

Retention depends on compliance requirements: SOC 2 requires 1 year, HIPAA requires 6 years, PCI DSS requires 1 year minimum, GDPR requires only as long as necessary (but logs are often exempt as they don't directly identify users). LoginRadius provides configurable retention policies and automated log archival to cold storage (S3, Azure Blob).

Audit logs are append-only, tamper-proof, and focused on compliance (authentication, authorization decisions, admin actions). Activity logs are broader, including non-security events, and may not have the same integrity guarantees. Audit logs have stricter retention and compliance requirements. LoginRadius provides both: detailed activity streams for analytics and compliance-grade audit logs with cryptographic integrity.

LoginRadius provides enterprise-grade audit logging with 40+ event types covering authentication, authorization, profile changes, and administrative actions. Our platform offers real-time log streaming via webhooks, historical audit logs with full-text search, configurable retention policies (1-6+ years), and out-of-the-box SIEM integrations (Splunk, ELK Stack). LoginRadius also provides pre-built compliance reports for SOC 2, ISO 27001, HIPAA, and PCI DSS.
