In which directory of the Filesystem Hierarchy Standard did a forensic expert identify binary files?

The identification of binary files within the Filesystem Hierarchy Standard (FHS) points to the significance of certain directories that are specifically designated for executable binaries and system management commands. The /sbin directory is intended to hold essential system binaries that are typically used for system administration tasks. This includes important commands needed for system maintenance and recovery, which often require elevated privileges to execute.

In a forensic investigation, finding binary files in the /sbin directory is pertinent because these files are executable programs that can significantly influence system operations or configurations. They often do not appear in the typical user environment and are critical for understanding the system's functionality and integrity, especially when investigating security incidents or system breaches.

The other directories mentioned serve different purposes. The /bin directory contains essential user commands that are required for all users, while /usr contains user-related programs and utilities, including applications and their libraries. The /etc directory primarily consists of configuration files and scripts rather than executable binaries. Each of these directories has a specialized role within the filesystem, but /sbin specifically stands out for containing those crucial binaries used for system management.
