Controlling Access to the Hierarchical File System › HFS Control Using the Native UNIX Security Model

HFS Control Using the Native UNIX Security Model

The HFS is a tree‑structured file system consisting of directories and files. It uses the forward slash (/).

Each file and directory is assigned an owning UID and an owning GID. The assignment is defined and saved in the file system, not in the external security product.

There are two methods to secure a HFS:

• Internal USS based on the UNIX model of security
• External security that uses standard CA Top Secret security authorizations

Important! These methods are mutually exclusive.
