This curriculum spans the technical and procedural rigor of a multi-phase SIEM deployment engagement, covering the same breadth of architectural design, operational integration, and compliance alignment found in enterprise-scale logging programs.

Module 1: Architectural Planning for SIEM Integration

  • Select appropriate ingestion topology (beats vs. log shippers vs. direct API ingestion) based on source system constraints and data volume.
  • Define log source categorization (security, system, application) to align with SIEM use cases and retention policies.
  • Assess network segmentation requirements for secure transmission of logs from production to ELK infrastructure.
  • Size Elasticsearch cluster nodes based on projected daily log volume, retention period, and query concurrency.
  • Determine index lifecycle management (ILM) policies for hot-warm-cold architectures to balance performance and cost.
  • Integrate TLS encryption and mutual authentication for all data transport layers within the logging pipeline.

Module 2: Log Source Onboarding and Normalization

  • Develop custom Filebeat modules for proprietary application logs requiring field extraction and parsing.
  • Map vendor-specific event IDs (e.g., Windows Event IDs, Cisco ASA codes) to MITRE ATT&CK techniques in ingest pipelines.
  • Implement conditional parsing in Logstash to handle schema variations across log source versions.
  • Validate timestamp accuracy and time zone consistency across distributed log sources during ingestion.
  • Configure failover mechanisms for log forwarders when primary Elasticsearch nodes are unreachable.
  • Enforce schema compliance using Elasticsearch index templates with strict field mappings.

Module 3: Detection Engineering and Rule Development

  • Write Elasticsearch query DSL rules to detect brute-force authentication patterns across multiple domains.
  • Develop anomaly detection jobs in Elastic Machine Learning to identify deviations in user login behavior.
  • Balance rule sensitivity to minimize false positives while maintaining detection coverage for critical threats.
  • Version-control detection rules using Git and implement CI/CD pipelines for rule deployment.
  • Correlate events across Windows Security, firewall, and proxy logs to identify lateral movement.
  • Set threshold-based triggers with sliding time windows to detect port scan activity.

Module 4: Index and Data Lifecycle Management

  • Configure ILM policies to roll over indices based on size or age and transition to warm tier storage.
  • Design index naming conventions that support time-based queries and automated retention enforcement.
  • Allocate shard counts based on index size and query patterns to prevent performance degradation.
  • Implement data stream architecture for write-heavy log indices to simplify management.
  • Define snapshot policies for nightly backups of critical security indices to remote repository.
  • Remove or archive indices containing PII after regulatory retention periods expire.

Module 5: Performance Optimization and Scalability

  • Tune Elasticsearch heap size and garbage collection settings to reduce node pause times.
  • Optimize slow queries by analyzing profile API output and rewriting aggregations.
  • Deploy dedicated ingest nodes to offload parsing work from data nodes under high load.
  • Implement search timeout and result size limits to prevent resource exhaustion from ad hoc queries.
  • Use index aliases to enable seamless reindexing without disrupting detection rules.
  • Monitor cluster health metrics (CPU, disk I/O, JVM pressure) for capacity planning.

Module 6: Access Control and Audit Governance

  • Configure role-based access control (RBAC) to restrict Kibana dashboards by team and sensitivity level.
  • Enable audit logging in Elasticsearch to track user actions on indices and security configurations.
  • Integrate with existing identity provider (e.g., Active Directory) via SAML or OIDC for centralized authentication.
  • Define field-level security to mask sensitive data (e.g., credit card numbers) in search results.
  • Assign detection rule ownership and require approval workflows for production deployment.
  • Conduct quarterly access reviews to deactivate unused service accounts and user privileges.

Module 7: Incident Response and Forensic Readiness

  • Preserve full-fidelity logs in cold storage for high-severity incidents to support legal admissibility.
  • Develop Kibana case management workflows to document investigation steps and evidence.
  • Export raw event data in STIX or JSON format for sharing with external incident response teams.
  • Validate log integrity using hash chaining or write-once storage to prevent tampering.
  • Simulate data loss scenarios to test recovery time for critical security indices.
  • Integrate with SOAR platforms via webhooks to automate containment actions from Kibana alerts.

Module 8: Compliance and Regulatory Alignment

  • Map log retention periods to regulatory requirements (e.g., PCI DSS, HIPAA, GDPR).
  • Generate audit reports demonstrating SIEM coverage for required control domains.
  • Implement data masking or tokenization for regulated fields within indexed documents.
  • Document data flow diagrams showing log movement from source to storage for compliance audits.
  • Configure alerting on unauthorized changes to SIEM rules or user permissions.
  • Conduct annual third-party assessments to validate logging completeness and integrity.
