What does live system forensics involve?

• A. Searching memory in real time on compromised hosts to identify system abuse
• B. Imaging a suspect hard drive while powered off
• C. Analyzing only archived logs
• D. Manual user interviews for memory recall

Answer: (A)

Live system forensics centers on volatile data from a running machine to understand what’s happening at the moment. This means gathering memory contents, running processes, open network connections, loaded modules, and other data that exists only while the system is powered on. By examining this real-time information on a compromised host, investigators can identify current abuse, active malware behavior, and attacker techniques that would vanish if the system were shut down or imaged only after the fact. Imaging a suspect hard drive while powered off captures non-volatile evidence but misses the transient, RAM-based artifacts essential for understanding a live intrusion. Analyzing only archived logs excludes the immediate context and recent activity that hasn’t yet been logged or has been altered by the incident. Manual user interviews for memory recall isn’t a reliable forensic data source and doesn’t provide the technical artifacts needed to reconstruct attacker actions.
