Digital Forensics Investigation
Digital forensics is the science of investigating crimes involving digital devices (computers, phones, servers). Tasks: preserve evidence (chain of custody), recover deleted files, analyze logs, identify malware, trace attackers, and generate forensic reports for court. Used by law enforcement, corporations, and security firms. Investigators analyze hard drives, memory dumps, network traffic, and application artifacts. Mastery takes 12-18 months. Pay: 20-30% premium because forensic skills are specialized, high-demand (cybercrime rising), and required by legal/compliance functions.
