Security is a blanket term which involves a variety of elements designed to mitigate potential risks and threats. In general, secure systems will control, through use of specific features, access to information that only properly authorized individuals, or processes operating on their behalf, will have access to read, write, create, or delete information. These controls can be used as a means of restricting or limiting access to data, functionality, or components. They may also be used to directly interdict potential threats or outside attack.
Corrective controls are procedures or mechanisms which enable recovery from the loss or damage.
The security of any system, organization, or environment is not the result of merely one or two system components. It is the result of a variety of features, controls, architectural decisions, and procedures combining and building upon each other to produce a security infrastructure.
