Maintaining system security
Every computer system needs protection from unauthorized
people accessing the computer, disks, and system files.
The security features present on your system represent
enhancements to the basic
security features of UNIX operating systems.
SCO systems are designed to meet the requirements
of the C2 class of trust as defined by the
Department of Defense
Trusted Computer System Evaluation Criteria
(also known as TCSEC or the Orange Book).
This chapter explains how to use the security features to maintain
a trusted system. Features affecting the ordinary user are described in
Chapter 9, ``Using a secure system'' in the Operating System User's Guide.
