Digital Forensics & Incident Response (DFIR)

About Digital Forensics & Incident Response (DFIR)

Digital forensics and incident response (DFIR) tools capture and analyze digital evidence after a security incident. The category includes disk forensics tools that create and examine forensic disk images, memory forensics frameworks that extract processes, network connections, and injected code from RAM dumps, and malware sandboxes that execute suspicious files in isolated environments to observe their behavior. Incident response platforms collect artifacts from endpoints across an organization, letting analysts search for indicators of compromise at scale. Tools like Autopsy and The Sleuth Kit provide graphical and command-line interfaces for disk image analysis, while Volatility processes memory dumps to reconstruct running processes and detect rootkits. Sandboxes like CAPE execute malware samples and produce reports on file system changes, network communications, and registry modifications. Endpoint collection tools like KAPE and Velociraptor gather forensic artifacts rapidly across thousands of machines, which is necessary when incident scope is unknown. The category overlaps with detection engineering, since IOCs discovered during DFIR investigations feed back into detection rules for future prevention.
