Chroot

Chroot, short for "change root," is a Unix/Linux system operation that allows a user to create an isolated environment within the file system. When a program is run in a chroot jail, it perceives a specific directory as the root directory, restricting its access to files outside this area. This enhances security by limiting what the program can see and access, making it harder for potential attackers to breach the system. Chroot is commonly used for testing, running software in a controlled setting, or isolating applications to minimize risks.
