3.6 Summary

 Information security is the prevention and protection of computer assets from unauthorized
access, use, alteration, degradation, destruction, and other threats.
 No longer can security be viewed as a backroom operation, separate from the essential
activity of an organization.

 Information assets are critical to any business and vital to the survival of any organization
in today’s globalize digital economy. Information leak is therefore intolerable.
 Information security is required because most organizations can be damaged by hostile
software or intruders.
 The major technical areas of information security are usually represented by the initials
CIA: confidentiality, integrity, and authentication or availability.

 Maintaining access control means not only that users can access only those resources and
services to which they are entitled, but also that they are not denied resources that they
legitimately can expect to access.
