Protected Files
The protection of two kinds of files is described here:
-
Disk files that are stored on disk packs
The mechanisms for protecting disk files extend to printer files, which are files in the printing subsystem that are awaiting printing on a mechanical device.
-
Tape files that are stored on magnetic tape
The file protection methods described here do not apply to users or programs running under a privileged usercode. Only minimal security checking applies to file access by privileged users.
These methods also vary depending upon any granulated authorization granted to a user, especially the READ, WRITE, EXECUTE, CHANGE, and REMOVE privileges. Refer to Controlling System Access for a description of granulated authorization.
