Security Information Event Management SIEM Review Checklist [FREE PDF]

Security Information and Event Management (SIEM) platforms are a foundational control required by NIST CSF 2.0 (DE.CM), ISO 27001:2022 Annex A 8.15 and 8.16, PCI DSS v4.0 Requirement 10, and SOC 2 Type II CC7.2 for continuous monitoring of security events. Regular SIEM operational reviews ensure that log sources are complete, detection rules are tuned, and alert queues are actively managed to identify threats before they escalate. This checklist provides Security Analysts and CISOs with a struct

  • Industry: Managed Security Services
  • Frequency: Weekly
  • Estimated Time: 30-45 minutes
  • Role: Security Analyst
  • Total Items: 37
  • Compliance: NIST CSF 2.0 DE.CM-01, ISO 27001:2022 Annex A 8.15 & 8.16, SOC 2 Type II CC7.2, PCI DSS v4.0 Requirement 10.4.1, CMMC 2.0 Practice AU.L2-3.3.1

Log Source Coverage and Completeness

Verify that all required log sources are onboarded, actively forwarding events, and meeting minimum event volume thresholds.

  • Are all critical log sources (firewalls, endpoints, identity providers, servers) actively forwarding logs to the SIEM?
  • Has the current log source inventory been compared against the authorized asset inventory to identify coverage gaps?
  • What is the total number of active log sources currently onboarded in the SIEM?
  • Were any log sources identified as silent or stopped forwarding events during the review period?
  • Are cloud platform logs (AWS CloudTrail, Azure Monitor, GCP Audit Logs) included in SIEM ingestion?
  • Please document any log sources identified as missing or offline during this review.

Detection Rule and Alert Management

Review the health and effectiveness of SIEM detection rules, use cases, and alert logic to ensure threat detection accuracy.

  • Are SIEM detection rules mapped to a recognized threat framework such as MITRE ATT&CK?
  • Have all active detection rules been reviewed for accuracy and relevance within the past 90 days?
  • Is there a documented false positive rate being tracked for high-severity alert rules?
  • Are critical detection rules protected from unauthorized modification using change controls?
  • What is the total number of active detection rules currently enabled in the SIEM?

Alert Triage and Response Performance

Assess the efficiency of alert triage workflows, mean time to respond, and escalation procedures.

  • Were all high and critical severity alerts from the review period triaged within the defined SLA?
  • Are there any open high or critical severity alerts from the review period that remain unresolved?
  • What was the average time to triage high-severity alerts during the review period in minutes?
  • Is there a documented escalation path for alerts that exceed the defined triage SLA?
  • Are alert triage outcomes (true positive, false positive, benign) consistently documented in a ticketing system?

Log Retention and Integrity Controls

Verify that logs are retained for the required period and protected against tampering or unauthorized deletion.

  • Are SIEM logs retained for the minimum period required by applicable regulations (minimum 12 months)?
  • Are log integrity controls (hash chaining or digital signatures) implemented to detect tampering?
  • Is SIEM storage capacity monitored with alerts for approaching capacity thresholds?
  • Are archived log records stored in a separate, access-controlled repository?
  • What is the current log retention period configured in the SIEM in days?

Compliance Use Case Coverage

Confirm that SIEM detection use cases address all mandatory monitoring scenarios required by applicable compliance frameworks.

  • Is privileged user activity (admin logins, privilege escalation, account changes) actively monitored in the SIEM?
  • Are failed authentication attempts and account lockout events generating SIEM alerts?
  • Are data exfiltration indicators (large outbound transfers, DLP alerts) correlated in the SIEM?
  • Are SIEM use cases reviewed against compliance requirements (PCI DSS, HIPAA, CMMC) at least annually?
  • Are vulnerability scan results and threat intelligence feeds integrated into SIEM correlation rules?

SIEM Platform Health and Performance

Evaluate the operational health, performance, and availability of the SIEM platform infrastructure.

  • Is SIEM platform uptime and availability being monitored with automated health check alerts?
  • Is the SIEM platform running the latest vendor-supported version with current security patches applied?
  • Are SIEM indexing performance metrics (events per second, query latency) within acceptable thresholds?
  • Is SIEM administrative access restricted to authorized security personnel only with MFA enforced?
  • Please capture a screenshot or photo of the SIEM health dashboard showing current platform status.

Incident Integration and Management Reporting

Assess how SIEM findings are integrated into the incident response workflow and reported to management.

  • Is the SIEM integrated with an incident response platform or SOAR for automated case creation?
  • Are weekly or periodic SIEM summary reports generated and reviewed by the CISO or Security Manager?
  • Are SIEM-detected incidents tracked through to closure with documented root cause analysis?
  • Were any confirmed security incidents detected via the SIEM during the review period?
  • Please provide the total count of alerts, confirmed incidents, and false positives during the review period.
  • Please document any SIEM improvement recommendations or action items identified during this review.
