In Linux forensics, what does the /proc filesystem provide access to?

• A. Real-time process and system information
• B. Physical disk image copies
• C. User home directories
• D. Kernel source code

Answer: (A)

The /proc filesystem is a virtual, live view into the kernel’s state, exposing real-time information about running processes and the system. In Linux forensics, this means you can peek into things like which processes are active, the commands used to launch them, memory maps, open file descriptors, CPU and memory details, and various kernel parameters. This data is dynamic and reflects the system at the moment you access it, which is crucial for understanding what the machine was doing during an incident, reconstructing activity, or validating later findings. It isn’t used to store physical disk images, user home directories, or the kernel source code—the latter would be found in the filesystem or source packages, not as live kernel state via /proc.
