A detailed overview of the key commands for digital forensics in Linux. Learn how to analyze logon activity, inspect running processes, recover deleted binaries, and investigate network activity. In addition, we will consider methods of searching for unusual files, analyzing installed programs, and detecting persistent access mechanisms in the system. This comprehensive guide will help security professionals quickly find and eliminate potential threats.
