Episode Synopsis

Summary



In this episode of Chattinn Cyber, Marc Schein is chattin’ with Devon Ackerman, a highly respected figure in the digital forensics and incident response (DFIR) community. Devon shares his background, starting from his upbringing in upstate New York, moving to Georgia, and how a chance encounter with an article about digital forensics at Champlain College sparked his interest in the field. He explains his early career in IT and web design during the dot-com boom, and how his curiosity and passion for troubleshooting led him to pursue digital forensics as a career.



Devon elaborates on the core concepts of digital forensics and incident response, describing digital forensics as the scientific discipline of preserving, validating, and interpreting digital data, often for legal purposes. Incident response builds on this foundation by focusing on reacting to cyber incidents, preserving evidence, and supporting organizations during and after attacks. He recounts his FBI career, highlighting a significant case involving espionage where a trusted insider stole sensitive data for a foreign government, demonstrating the real-world impact and importance of DFIR work.



The conversation shifts to emerging cyber threats and the evolving landscape of cyber risk. Devon emphasizes that threat actors are highly motivated, whether financially or politically, and continuously adapt to stay ahead of defenders. He discusses the widespread availability of offensive cyber capabilities among nation-states and criminal groups, and how geopolitical tensions can influence cyber activity. The discussion also touches on the role of AI in cybersecurity, acknowledging its potential benefits but warning about risks related to rapid adoption without adequate security controls.



Devon addresses the insider threat, distinguishing between malicious insiders and those who pose risks unintentionally through mistakes or misconfigurations. He stresses that human factors remain a critical vulnerability in cybersecurity, as trusted employees can inadvertently expose sensitive data. He offers advice for newcomers to the DFIR field, encouraging a mindset of continuous learning, experimentation, and resilience in the face of failure, noting the complexity and ever-changing nature of digital forensics.



Finally, Devon describes his current role at Cybereason, a cybersecurity company known for its endpoint detection and response technology. He explains how Cybereason has expanded its services to include both proactive advisory and reactive incident response capabilities, supporting clients globally across the entire cyber risk lifecycle. He provides contact information for listeners interested in learning more or engaging their services, and the episode concludes with Marc thanking Devon for sharing his insights and experiences.
