Secure Subsystem Restrictions.

Abstract

The objective of this task is to modify the Time Sharing System (TSS) available in the H6000, in order to prevent the restricted user from penetrating outside the MDQS subsystem, and to report any attempts made by the restricted user to do so. Additional constraints will be provided by the following two conditions: The User Profile Systems (UPS's of MDQS) will be used to prevent the use of the PERF and PRIV commands by the restricted user, and The restricted USERID will be created in a File Management Supervisor (FMS) activity with no CARDIN, TALK, LODS, or LODX permissions. The changes to TSS will be implemented so as to allow for the restriction to be a site option. This document includes a technical report on the changes to TSS and on the structure and security of the Management Data Query System (MDQS). Also included is a report on the characteristics of a user-defined subsystem on the Command Library (CMDLIB) which are necessary to maintain the security of the MDQS environment. (Author)
