This curriculum spans the technical, procedural, and coordination challenges of integrating digital forensics into ongoing SOC operations, comparable in scope to developing a cross-functional incident response capability across hybrid environments, cloud platforms, and compliance frameworks.
Module 1: Integrating Digital Forensics into SOC Workflows
- Decide whether to embed forensic analysts within SOC shifts or maintain a separate incident response unit with on-call rotation.
- Implement standardized triage protocols that determine when an alert triggers full disk imaging versus memory capture.
- Balance detection speed with forensic readiness by configuring SIEM correlation rules to preserve relevant metadata for later chain-of-custody validation.
- Establish data retention policies for endpoint telemetry that support retrospective analysis without violating storage compliance limits.
- Coordinate with network operations to ensure packet capture (PCAP) systems are available at chokepoints and preserved during active investigations.
- Define handoff procedures between Tier 2 analysts and forensic specialists, including required documentation and evidence labeling formats.
Module 2: Evidence Acquisition Across Hybrid Environments
- Select between agent-based and live boot acquisition methods for compromised systems based on system availability and anti-forensics risks.
- Configure write-blockers and forensic boot media for physical workstation collections while maintaining audit logs of device access.
- Use cloud provider APIs to snapshot virtual machines in AWS, Azure, or GCP while preserving region, time, and account context.
- Document chain-of-custody for evidence transferred between on-premises labs and third-party cloud forensic vendors.
- Address encryption challenges by extracting BitLocker or FileVault recovery keys from domain controllers or backup systems.
- Preserve volatile memory from containers and serverless functions using runtime introspection tools before instance termination.
Module 3: Timeline Analysis and Event Reconstruction
- Normalize timestamps across endpoints, firewalls, and cloud logs to build a unified timeline despite system clock drift.
- Correlate Windows Prefetch, ShimCache, and NTUSER.DAT artifacts to identify execution of unauthorized binaries.
- Reconstruct lateral movement paths using Windows Security Event IDs 4624, 4648, and PowerShell operational logs.
- Resolve gaps in logging coverage by inferring activity from file system metadata (e.g., MFT entries, $LogFile analysis).
- Validate timeline accuracy by cross-referencing DNS query logs with endpoint process creation events.
- Use SQLite databases from browsers and messaging apps to establish user activity patterns during compromise windows.
Module 4: Malware Triage and Artifact Extraction
- Isolate and analyze suspicious files in air-gapped sandbox environments with network simulation to observe C2 behavior.
- Extract embedded payloads from Office documents using oledump.py and analyze VBA macros for obfuscation techniques.
- Identify persistence mechanisms by mapping registry run keys, scheduled tasks, and WMI event filters to known malware families.
- Use YARA rules to scan memory dumps for shellcode patterns and decrypt configuration blobs in real time.
- Compare file hashes against internal threat intelligence platforms to determine if malware is novel or part of a known campaign.
- Document indicators of compromise (IOCs) in STIX/TAXII format for automated dissemination across security tools.
Module 5: Cloud and Identity Forensics
- Analyze AWS CloudTrail or Azure AD audit logs to trace privilege escalation via role assumption or service principal misconfigurations.
- Map SSO and identity provider logs (e.g., Okta, Azure AD) to endpoint activity to confirm or rule out account compromise.
- Reconstruct access patterns from S3 bucket access logs and IAM policy evaluations during data exfiltration incidents.
- Extract session tokens from memory dumps and validate their active status through cloud provider APIs.
- Investigate lateral movement in multi-tenant SaaS environments using application-level audit logs and user behavioral analytics.
- Reconcile identity federation events with on-premises Active Directory replication logs to detect Golden Ticket attacks.
Module 6: Legal and Regulatory Compliance in Evidence Handling
- Design evidence storage architecture to meet jurisdiction-specific data sovereignty requirements for cross-border investigations.
- Implement hashing and digital signing of forensic images to maintain admissibility in legal proceedings.
- Restrict access to forensic data based on role-based permissions and document all examiner activities in audit trails.
- Coordinate with legal counsel to determine when to involve law enforcement and preserve evidence under legal hold.
- Redact personally identifiable information (PII) from forensic reports before sharing with external auditors.
- Validate forensic tool accuracy and reliability for potential courtroom scrutiny using NIST CMVP or vendor validation reports.
Module 7: Automation and Scalability of Forensic Processes
- Develop playbooks in SOAR platforms to automate evidence collection steps for common incident types like ransomware or phishing.
- Integrate endpoint detection and response (EDR) tools with forensic frameworks to trigger memory and disk captures remotely.
- Use scripting to batch-process forensic images for artifact extraction (e.g., browser history, USB device IDs) across multiple hosts.
- Deploy distributed forensic processing clusters to handle large-scale investigations without overloading central servers.
- Validate automation outputs against manual analysis to prevent false negatives in IOC detection.
- Monitor forensic tool performance and update parsers regularly to support new operating system versions and file formats.
Module 8: Threat Actor Attribution and Reporting
- Correlate infrastructure reuse (IPs, domains, certificates) across incidents to identify persistent threat actors.
- Map TTPs from MITRE ATT&CK to observed behaviors and assess confidence levels based on artifact reliability.
- Use linguistic analysis on phishing emails or ransom notes to support attribution to specific threat groups.
- Document investigation findings in structured reports that separate observed data from analytical conclusions.
- Share anonymized threat intelligence with ISACs while ensuring operational security and protecting sources.
- Conduct peer review of forensic conclusions to reduce cognitive bias and strengthen investigative rigor.
