ABSTRACT
Security is generally defined as the freedom from danger or as the condition of safety. Computer security,
specifically, is the protection of data in a system against unauthorized disclosure, modification, or
destruction and protection of the computer system itself against unauthorized use, modification,
or denial of service. Because certain computer security controls inhibit productivity, security is typically
a compromise toward which security practitioners, system users, and system operations and adminis-
trative personnel work to achieve a satisfactory balance between security and productivity.
