Abstract - Digital forensics is essential for investigating cyber incidents because modern crimes leave digital traces on devices and services. A wide range of tools both commercial and open-source help examiners acquire, analyze, and report on evidence. This paper compares four widely used forensic tools (EnCase, FTK, Autopsy, and X-Ways) against practical performance parameters: acquisition/processing speed, accuracy/recovery, usability, platform and file-system support, resource usage, reporting, and cost. The comparison is based on vendor documentation, standards guidance, and recent comparative studies. The goal is to help students and beginner investigators choose tools appropriate to their needs and resources.
Keywords -Digital Forensics, Cybersecurity, Digital Evidence, Forensic Tools, Performance Analysis
