The primary duty of the Cyber Security Analyst III (Digital Forensics) is the planning and execution of digital forensic investigations, support of electronic discovery (e-discovery) activities, and assistance with incident response efforts across the organization's federal information systems at the Hanford Site. The incumbent applies forensically sound methodologies to preserve, collect, analyze, and document digital evidence from a variety of sources including endpoints, servers, network logs, mobile devices, and cloud environments. The role collaborates closely with Legal, HR, IT Operations, and GRC teams, and ensures all investigative activities maintain chain of custody integrity and comply with applicable federal regulations and organizational policy.

Major Activities (Typical Duties/Responsibilities)

• Conduct end-to-end digital forensic investigations, including evidence identification, preservation, acquisition, analysis, and reporting in accordance with accepted forensic standards (e.g., NIST SP 800-86).
• Perform forensic imaging and analysis of physical and virtual endpoints (Windows, Linux, macOS), storage media, and mobile devices using industry-standard tooling.
• Support electronic discovery (e-discovery) activities, including data identification, legal hold implementation, collection, processing, and production in coordination with Legal counsel.
• Analyze file systems, registry artifacts, browser history, email archives, log files, and other digital artifacts to reconstruct timelines and identify indicators of malicious or unauthorized activity.
• Conduct memory forensics and volatile data analysis during active incident response to identify malware, injected code, and attacker persistence mechanisms.
• Support network forensics activities, analyzing packet captures and network flow data to reconstruct communications and identify data exfiltration or lateral movement.
• Maintain rigorous chain of custody documentation for all evidence, ensuring admissibility and defensibility in administrative, civil, or law enforcement proceedings.
• Collaborate with the Security Operations team to support incident response activities, providing forensic analysis to characterize scope, root cause, and attacker activity.
• Produce clear, thorough forensic investigation reports and executive summaries suitable for legal review, management briefings, and regulatory submissions.
• Manage and maintain the forensic lab environment, including hardware, licensed tooling, write blockers, and evidence storage in compliance with evidence handling policies.
• Provide mentorship and technical guidance to junior analysts on forensic methodology, tool usage, evidence handling, and documentation standards.
• Stay current on evolving forensic techniques, anti-forensic methods, and legal and regulatory requirements affecting digital evidence handling.
• Perform other duties as appropriate and as assigned.
