Core Responsibilities

Primary Functions

Perform forensic acquisitions of storage media (HDD, SSD, removable media) and system images using industry-standard tools (EnCase, FTK Imager, dd, X-Ways) while documenting hash values, acquisition methodology, and maintaining a full chain-of-custody record suitable for legal proceedings.
Conduct full-disk and targeted forensic analysis to identify indicators of compromise (IOCs), timeline reconstructions, data exfiltration paths, user activity, deleted and hidden files, and evidence of tampering or malicious software.
Execute volatile memory captures and memory forensics analysis (using Volatility, Rekall) to recover process artifacts, credentials, injected code, persistence mechanisms, and malware in-memory behaviors that are not present on disk.
Analyze mobile device data including iOS and Android extractions and logical/physical analyses using Cellebrite, MSAB, Oxygen Forensics, or open-source alternatives; recover deleted messages, call logs, app artifacts, geolocation data, and locked/encrypted device content.
Support incident response engagements by triaging affected systems, prioritizing evidence collection, isolating compromised hosts, and delivering timely forensic findings to incident response and SOC teams to enable containment and remediation.
Perform malware triage and static/dynamic analysis to attribute malicious binaries, extract network indicators, identify command-and-control behaviors, and produce IOC feed entries for detection engineering and threat hunting.
Conduct network forensics by collecting and analyzing logs, packet captures, firewall and proxy data to trace lateral movement, data staging, and exfiltration; correlate multi-source telemetry to validate attack narratives.
Prepare detailed, court-ready forensic reports that communicate technical findings in clear language for stakeholders, legal teams, and non-technical executives, including reproducible methods, timelines, evidence lists, and recommended remediation.
Provide expert witness testimony in civil and criminal proceedings; prepare affidavit and deposition materials and be available to explain forensic methods, tool output, and evidence handling to judges and juries.
Validate and verify forensic tool output through cross-tool correlation and reproducibility checks to ensure defensible conclusions and reduce false positives in investigative results.
Maintain and manage forensic evidence inventory, secure storage, and disposition processes in accordance with organizational policy, legal requirements, and chain-of-custody best practices.
Develop and execute repeatable, scriptable forensic processes (PowerShell, Python, Bash) to automate common acquisition and analysis tasks, improve throughput, and reduce human error in evidence handling.
Collaborate with legal, HR, compliance, and privacy teams to ensure forensic activities comply with data protection laws, search warrants, court orders, and internal policies while preserving investigator independence.
Provide subject-matter expertise to SOC, IR, and threat hunting teams on forensic artifacts, data sources, and detection opportunities; assist in tuning SIEM rules, endpoint detection, and logging frameworks to improve future visibility.
Conduct forensic analysis of cloud environments (AWS, Azure, GCP) including snapshot acquisition, log analysis (CloudTrail, Azure Activity Logs), and cloud artifact examination to identify compromised accounts, misconfigurations, and data leakage.
Employ data carving and file signature analysis to recover partially overwritten or fragmented files, reconstruct deleted records, and recover evidence from formatted or corrupted media.
Mentor junior forensic analysts and investigators by designing training modules, conducting case reviews, and performing quality assurance on forensic artifacts and reports.
Participate in tabletop exercises, red/blue team collaborations, and post-incident reviews to refine forensic playbooks, evidence requirements, and response runbooks based on lessons learned.
Lead or participate in pro-bono or law enforcement support investigations when required; coordinate evidence transfer and legal liaison activities with external agencies while protecting chain-of-custody and evidentiary integrity.
Stay current with digital forensics research, emerging artefacts, new encryption and anti-forensic techniques, and evolving legal precedents to ensure investigative techniques remain effective and defensible.
Design and maintain forensic lab environments and secure acquisition workstations, ensure forensic tooling licensing and patching, and enforce documented standard operating procedures (SOPs) for lab use.

Secondary Functions

Create and maintain forensic playbooks, runbooks, and standard operating procedures that align with NIST, SANS, ISO 27001, and organizational requirements.
Support eDiscovery processes by identifying relevant electronic evidence, producing metadata exports, and coordinating with legal teams on preservation orders and litigation holds.
Assist in detection engineering efforts by translating forensic findings into rules, signatures, and use cases for SIEMs, EDR platforms, and network monitoring.
Provide ad-hoc data recovery and analysis support for HR investigations, insider threat cases, and executive inquiries following established legal boundaries.
Contribute to hiring, training, and capacity planning for the digital forensics team; recommend staffing levels and tooling investments based on case volume and complexity.
Participate in vendor evaluation and proof-of-concept trials for new forensics solutions, and recommend integrations that improve evidence capture, chain-of-custody, or analysis speed.
Engage in cross-functional projects to harden logging, endpoint telemetry, and secure backup strategies that increase forensic readiness and reduce time-to-evidence in future incidents.
