Chroot Jail

Definitions

1. A Unix isolation technique that changes a process's apparent root directory, restricting how it can access parts of the filesystem. Chroot jails provide limited containment, but they are not a complete sandbox on their own.

   In plain English: A Unix technique that restricts a process to a limited part of the filesystem.

   Example: "The old FTP daemon ran inside a chroot jail to reduce filesystem exposure if it was compromised."
