Computer Security

Introduction to Computer Security

Computers today are very important, and even integral to all aspects of the activities and operations of organizations and even individuals. As we become critically dependent upon computer information system, we recognize that computers and computer-related problems must be understood and managed, the same as any other resource.

Adequately secure systems deter, prevent, or detect unauthorized disclosure, modification, or use of information. Much of today’s information and data requires protection from intruders, as well as from individuals with authorized computer access privileges who attempt to perform unauthorized actions. Protection is achieved not only by technical, physical and personnel safeguards, but also by clearly articulating and implementing policy regarding authorized system use to information users and processing personnel at all levels.

Security protects an information system from unauthorized attempts to access information or interfere with its operation. <>
