How to Chroot SSH Users on Centos 7

The term chroot refers to a process of creating a virtualized environment in a Unix operating system, separating it from the main operating system and directory structure. This process essentially generates a confined space, with its own root directory, to run software programs. This virtual environment runs separately from the main operating system’s root directory. Any software program run in this environment can only access files within its own directory tree. It cannot access files outside of that directory tree.
