The chroot (change root) ability is a Unix-based feature that allows a process to run in a confined environment where it can only access files and resources within a specified directory tree, also known as a "chroot jail". By using chroot, an administrator can create a segregated area on a filesystem where a process and its children can run, without being able to access files outside of that area. This can be useful for enhancing security, as it limits the potential impact of a compromised process or user account. Many web servers and FTP servers use chroot to isolate the execution environment of a website or user, respectively.
