Assigns a security level to the jobs of the proper user.

Format

  1. SECURITY HIGH
  2. SECURITY NORMAL
  3. SECURITY LOW

Forbidden contexts

NO USER

Execution

A user who is at HIGH or NORMAL security is restricted in the type of job (MOP or BACKGROUND) that he is allowed to initiate in NO USER context, although in some cases he is merely requested to give his password. The requirements of the user who issues any of the commands that initiate jobs ( JOB, RUNJOB, LOGIN and CONNECT) or create filestore files (INPUT) in NO USER context are tabulated below.

Context Command SECURITY HIGH SECURITY NORMAL SECURITY LOW
MOP,NO USER INPUT Not allowed Not allowed No password required
JOB
RUNJOB
LOGIN
CONNECT
Password required Password required No password required
BACKGROUND,NO USER INPUT No password required No password required No password required
JOB
RUNJOB
Not Allowed No password required No password required

Thus, users in an environment where they are not concerned with security, may set themselves at LOW security and avoid having to type a password each time they LOGIN.

Note that users are initially set at NORMAL security.
