Chapter 1 Description of the HP-UX Trusted System

The Hewlett-Packard C2-level trusted system consists of the HP-UX Release 10.10 operating system configured in trusted mode and its commands, utilities, and subsystems along with supported hardware. This results in a system designed to meet the criteria of a C2-level trusted system, as described in Section 2.2 of the Department of Defense Trusted Computer System Evaluation Criteria, DOD 5200.28-STD, December 1985, and the E3/FC2 security level as definded by the Information Technology Security Evaluation Criteria (ITSEC) established by the European Community.

This chapter defines a trusted system. It introduces fundamental security terms and concepts and summarizes the major security features enforced by the HP-UX C2-level system. It provides an overview of the HP-UX C2-level system and outlines administrative roles and functions necessary to maintain a trusted system. It also discusses background for planning system security including a section on developing a security policy for your department.

	NOTE: This chapter is written for system administrators whose responsibility it is to maintain the system. When this chapter refers to "you," it is directed towards such system administrators, presumably those having superuser (root) privilege on the HP-UX C2-level system.
