Progress Tracking

Phase 1: SIEM Installation (100% Complete) ✅

Component: SIEM Platform Setup

• Install Splunk infrastructure (120 min)
• Configure indexers and search heads (90 min)
• Set up deployment server (60 min)
• Configure SSL certificates (45 min)
• Test basic functionality (30 min)

Lessons Learned: Splunk clustering requires significant system resources and proper network configuration Issues Overcome: SSL certificate configuration required custom certificate authority setup

Phase 2: Log Ingestion (95% Complete) 🔄

Component: Data Collection

• Configure Windows event collection (60 min)
• Set up Linux log forwarding (45 min)
• Configure network device logging (60 min)
• Set up application log collection (45 min)
• PENDING: Test log ingestion (30 min)

Lessons Learned: Universal forwarders require proper configuration for optimal log collection Issues Overcome: Windows event log collection needed custom inputs configuration

Phase 3: Detection Rules (85% Complete) 🔄

Component: Detection Logic

• Create basic detection rules (90 min)
• Configure alerting thresholds (45 min)
• Set up correlation searches (60 min)
• Create custom dashboards (60 min)
• PENDING: Test detection accuracy (45 min)

Lessons Learned: Effective detection rules require balance between sensitivity and false positive rates Issues Overcome: Correlation searches needed optimization for large data volumes

Phase 4: Threat Hunting (75% Complete) 🔄

Component: Proactive Hunting

• Develop hunting queries (120 min)
• Create hunting playbooks (90 min)
• Set up hunting dashboards (60 min)
• PENDING: Configure threat intelligence feeds (45 min)
• PENDING: Document hunting procedures (45 min)

Lessons Learned: Threat hunting requires deep understanding of normal network behavior Issues Overcome: Complex hunting queries needed performance optimization

Phase 5: Incident Response (60% Complete) 🔄

Component: Response Procedures

• Create response playbooks (90 min)
• Configure automated responses (60 min)
• Set up incident tracking (45 min)
• PENDING: Create response dashboards (45 min)
• PENDING: Test response procedures (60 min)

Lessons Learned: Automated response procedures require careful testing to avoid false positives Issues Overcome: Incident tracking integration needed custom field configuration
