ABSTRACT
Computer security is the protection of computing assets and computer network communication assets against
abuse, unauthorized use, and unavailability caused by intentional or unintentional actions, and protection
against undesired information disclosure, alteration, or misinformation. In today’s environment, the subject
encompasses computers ranging from supercomputers to microprocessor-based controllers and micro-
computers, personal digital assistants (PDAs), software, peripheral equipment (including terminals, printers),
communication media (e.g., cables, antennas, satellites), people who use computers or control computer
operations, and networks (some of global extent) that interconnect computers, terminals, and other
peripherals.
