Log Management & SIEM Audit Checklist [FREE PDF]

Effective log management and SIEM configuration are foundational requirements under ISO/IEC 27001:2022 Annex A 8.15 (Logging) and NIST CSF DE.CM-7, mandating that organizations collect, protect, and analyze event logs to detect anomalies and support incident response. PCI DSS v4.0 Requirement 10 further mandates that all access to system components and cardholder data is logged and reviewed at least daily. This audit checklist enables IT Managers and CISOs to systematically verify that log sourc

Log Source Coverage & Onboarding

Verify that all required log sources are forwarding data to the SIEM and no critical systems are excluded.

  • Are all critical servers and endpoints configured to forward logs to the SIEM?
  • Are network devices (firewalls, switches, routers) included as active log sources?
  • Are cloud platform logs (AWS CloudTrail, Azure Monitor, GCP Audit Logs) integrated into the SIEM?
  • Is there a documented and up-to-date log source inventory maintained?
  • Are there any known log source gaps or recently decommissioned sources not yet removed from inventory?

Log Integrity & Tamper Protection

Confirm that logs are protected from unauthorized modification or deletion.

  • Are logs written to a write-once or append-only storage medium or system?
  • Is log file integrity monitoring (FIM) enabled on SIEM log storage directories?
  • Are log transmission channels encrypted in transit (e.g., TLS 1.2+)?
  • Are access controls restricting who can delete or modify stored log data properly configured?
  • Are hash or checksum validations used to verify log file integrity?

Log Retention & Archival Policy

Ensure log retention periods align with applicable regulatory minimums and organizational policy.

  • Is a formally documented log retention policy in place and approved by management?
  • Are audit logs retained for a minimum of 12 months, with at least 3 months immediately available?
  • What is the current configured log retention period in the SIEM (in days)?
  • Are archived logs stored in a secure, access-controlled location separate from production systems?
  • Has the log restoration and retrieval process been tested within the past 12 months?

SIEM Alert Rules & Use Case Management

Review the effectiveness, coverage, and maintenance of SIEM detection rules and correlation logic.

  • Is there a formal process for creating, reviewing, and approving new SIEM alert rules?
  • Are SIEM rules reviewed and tuned at least quarterly to reduce false positives?
  • Are detection rules mapped to a threat intelligence framework (e.g., MITRE ATT&CK)?
  • Are high-severity alerts configured to trigger automated notifications to security personnel?
  • How many active detection rules are currently deployed in the SIEM?

Daily Log Review & Monitoring Procedures

Confirm that log review activities are performed at the required frequency and documented appropriately.

  • Are logs reviewed at least once daily by qualified security personnel or automated tooling?
  • Is evidence of daily log review activities documented and retained?
  • Are privileged user and administrator actions specifically reviewed for anomalous behavior?
  • Are failed login attempts and account lockout events actively monitored and alerted?
  • Are escalation procedures documented for alerts that remain unacknowledged beyond a defined SLA?

SIEM Health, Performance & Availability

Assess the operational health of the SIEM platform to ensure continuous and reliable log ingestion.

  • Is SIEM platform uptime and availability monitored with defined SLA targets?
  • Are SIEM ingestion pipelines monitored for data lag or ingestion failures?
  • Is there automated alerting when log source forwarding drops below expected event-per-second thresholds?
  • Is the SIEM platform patched and running a supported software version?
  • Provide any additional notes on SIEM health issues or open remediation items.

SIEM Access Control & User Permissions

Verify that access to the SIEM platform is appropriately restricted and reviewed.

  • Is role-based access control (RBAC) enforced on the SIEM platform?
  • Is multi-factor authentication (MFA) required for all SIEM administrator accounts?
  • Has a formal review of SIEM user accounts been conducted within the past 90 days?
  • Are service accounts used for log forwarding operating under least-privilege principles?
  • Attach or reference the most recent SIEM access review report.
