NAME
     protection - The operating system's protection mechanisms

DESCRIPTION
     There are two fundamental object protection mechanisms: access control
     lists (ACLs) and protected subsystems.  By object protection mechanisms
     we mean the ways that objects (files, directories, etc.) can be
     protected, as opposed to the way the operating system protects its own
     integrity.

     "ACLs" are primarly a way of specifying WHO can access an object (with
     the ordinary types of operations, like read, write, and execute for
     files). Type 'help protection acls' for detailed information about ACLs.

     "Protected subsystems" are a way of specifying HOW an object can be
     accessed (in more complicated ways than just read, write, and execute).
     A protected subsystem is a way to guarantee the integrity and/or privacy
     of data.  Type 'help protection protected_subs' for detailed information
     about protected subsystems.
