Automation Strategies by Incident Phase
1. Detection and Triage Automation
Automated Alert Correlation
Multi-Source Data Fusion
- Combine alerts from SIEM, EDR, NDR, and other security tools
- Apply correlation rules to identify related events
- Reduce alert noise through deduplication
- Prioritize alerts based on risk scores and business impact
Threat Intelligence Enrichment
- Automatically enrich IOCs with threat intelligence
- Perform reputation checks on IPs, domains, and file hashes
- Correlate with known attack campaigns and threat actors
- Provide context for analyst decision-making
Automated Initial Assessment
Risk Scoring Algorithms
- Calculate risk scores based on multiple factors
- Consider asset criticality and business impact
- Incorporate threat intelligence and historical data
- Dynamically adjust scores based on new information
Automated Evidence Collection
- Gather relevant logs, network traffic, and system information
- Preserve volatile data before it’s overwritten
- Create forensic images and memory dumps
- Collect configuration and system state information
2. Investigation and Analysis Automation
