In the domain of digital forensics, volatile data assumes a paramount
role, characterized by its ephemeral nature. Analogous to fleeting
whispers in a bustling city, volatile data in Linux systems resides
transiently within the Random Access Memory (RAM), encapsulating
critical system configurations, active network connections, running
processes, and traces of user activities. Once a Linux machine powers
down, this ephemeral reservoir of information dissipates swiftly,
rendering it irretrievable. read more....
Traditionally, Unix/Linux/POSIX filenames can be almost any sequence of bytes, and their meaning is unassigned. The only real rules are that "/" is always the directory separator, and that filenames can't contain byte 0 (because this is the terminator). Although this is flexible, this creates many unnecessary problems. In particular, this lack of limitations makes it unnecessarily difficult to write correct programs (enabling many security flaws), makes it impossible to consistently and accurately display filenames, causes portability problems, and confuses users. more ....
