- Anyone out there know what the /SECRECY and /INTEGRITY qualifiers to
- the commands DIRECTORY, READ, SELECT and SET FOLDER in MAIL do?
-
- ; DEFINE VERB DIRECTORY
- ...
- ; QUALIFIER SECRECY, VALUE(REQUIRED,TYPE=$ACL)
- ; QUALIFIER INTEGRITY, VALUE(REQUIRED,TYPE=$ACL)
- ...
- [additional definitions omitted]
-
- They don't do anything, unless you have the SE/VMS (Security Enhanced VMS)
- package. SE/VMS supports non-discretionary access controls, which involve
- marking a variety of objects with secrecy and integrity levels. MAIL
- messages are among these objects, and presumably these qualifiers allow you
- to restrict commands to work only on messages at some secrecy or integrity
- level.
-
- There are any number of places in VMS where small hooks for SE/VMS exist.
- The most common hook people notice is the UPGRADE and DOWNGRADE services.
- In all these cases, the "guts" of the access controls only come with SE/VMS;
- what you are seeing are minor surface manifestation that were more convenient
- put into every shipped VMS system, rather than patching them in later.
