• wikipedia.org (ref: en.wikipedia.org/wiki/Computer_security) standardizes Computer Security as "Computer security is the effort to create a secure computing platform, designed so that agents (users or programs) can only perform actions that have been allowed. This involves specifying and implementing a security policy. The actions in question can be reduced to operations of access, modification and deletion. Computer security can be seen as a subfield of security engineering, which looks at broader security issues in addition to computer security."
  
  
• utmb.edu (ref: www.utmb.edu/is/security/glossary.htm) defines Computer Security as "Those measures, procedures, or controls which provide an acceptable degree of safety of information resources from accidental or intentional disclosure, modification, or destruction."
