SECURITY CLASSIFICATION SYSTEM (Preferred term)
A set of procedures for identifying and protecting official information whose disclosure could have adverse consequences for the Commonwealth. The security classification system is implemented by assigning markings (such as TOP SECRET or PROTECTED and so) on that show the value of the information and indicate the minimum level of protection it must be afforded.
