Forensic Investigation Methodology

Phase 1: Evidence Collection and Preservation

Investigation begins with comprehensive evidence collection preserving system state before analysis alters environments. Collection includes complete log file gathering, disk imaging of compromised systems, memory dumps capturing volatile data, configuration backups, database snapshots, and network traffic captures. Evidence preservation uses cryptographic hashing, write-protection, chain of custody documentation, and secure storage. Proper collection ensures investigation has complete information while maintaining evidence integrity for potential legal proceedings. Premature system changes destroy evidence—professional procedures preserve maximum intelligence.

Phase 2: Log Aggregation and Normalization

Logs from multiple sources require aggregation into centralized repository for correlation analysis. Normalization converts varying log formats into common structure enabling cross-source analysis. Time synchronization aligns log entries from systems with different clocks creating accurate chronology. Data enrichment adds context—IP geolocation, threat intelligence, DNS resolution, and user identification. Aggregated normalized logs enable comprehensive analysis impossible with fragmented sources. Professional tools handle log volume—gigabytes of logs require specialized parsing and indexing.

Phase 3: Pattern Recognition and Anomaly Detection

Automated analysis identifies suspicious patterns and anomalies requiring investigation. Pattern recognition detects SQL injection attempts, directory traversal attacks, brute force login campaigns, automated scanning, and known exploit signatures. Anomaly detection identifies unusual access patterns, unexpected data transfers, privilege escalations, and outlier behaviors. Automated analysis processes log volume highlighting items requiring expert examination. However, automation alone misses sophisticated attacks—expert analysis interprets patterns understanding attack context and identifying subtle indicators.

Phase 4: Timeline Reconstruction

Timeline construction correlates events creating chronological attack narrative. Super-timeline combines all log sources ordering events precisely. Timeline visualization reveals attack progression—initial reconnaissance, exploitation, privilege escalation, lateral movement, data exfiltration, and cleanup. Interactive timeline tools enable drilling into specific periods examining detailed activity. Timeline becomes investigation centerpiece—comprehensive chronology revealing complete attack story from first suspicious activity through final attacker action. Professional reconstruction accounts for time zones, clock skew, and log gaps presenting accurate chronology.

Phase 5: Root Cause Determination

Root cause analysis traces attack backward identifying initial compromise vector. Investigation examines earliest attack indicators in timeline working backward identifying how attackers gained access. Common root causes visible in logs include vulnerable plugin exploitation shown in exploit strings, SQL injection evident in malformed queries, file upload vulnerabilities revealed in POST requests, credential compromise shown in successful logins from suspicious IPs, and phishing visible in email logs followed by compromised sessions. Root cause identification is investigation goal—knowing how compromise occurred enables targeted remediation preventing recurrence.

Phase 6: Impact Assessment and Reporting

Final investigation phase assesses breach impact and documents findings. Impact assessment determines compromised systems, accessed data, exfiltrated information, and business consequences. Comprehensive report documents methodology, timeline, root cause, impact assessment, evidence inventory, Indicators of Compromise, and remediation recommendations. Executive summary presents key findings for non-technical audiences. Technical appendix provides detailed analysis supporting conclusions. Reports serve multiple purposes—regulatory submissions, insurance claims, legal proceedings, board presentations, and security improvements. Professional reporting transforms technical investigation into actionable business intelligence.
