Effective operating system security measures help
prevent unauthorized access and theft of computer time and any kind
of sensitive information, such as marketing plans, formulas, or proprietary
software. These measures can also protect equipment, software, and
files from damage caused by tampering.
This chapter provides security administrators
with an overview of security measures available with the operating
system. “Security for the System Administrator” provides
more specific information regarding site security policies, the tasks
of security administrators, and methods of protecting site computer
systems and resources.
