Control measure means safety control technology to achieve their business objectives set security control, configuration methods, and various regulatory regimes. Control Test is a variety of security measures to control the enterprise consistency with a predetermined safety standards compared to determine the presence or absence of the control measures, if implemented, to guard against vulnerabilities are valid evaluation of business safety measures may depend on the degree.
