Information is categorized according to its information type. An information type is a specific category of information (e.g., privacy, medical, proprietary, financial, investigative, contractor sensitive, security management) defined by an organization or, in some instances, by a specific law, Executive Order, directive, policy, or regulation.


Adverse effects on individuals may include, but are not limited to, loss of the privacy to which individuals are entitled under law.


System information (e.g., network routing tables, password files, and cryptographic key management information) must be protected at a level commensurate with the most critical or sensitive user information being processed, stored, or transmitted by the information system to ensure confidentiality, integrity, and availability.


The potential impact value of not applicable only applies to the security objective of confidentiality.


It is recognized that information systems are composed of both programs and information. Programs in execution within an information system (i.e., system processes) facilitate the processing, storage, and transmission of information and are necessary for the organization to conduct its essential mission-related functions and operations. These system processing functions also require protection and could be subject to security categorization as well. However, in the interest of simplification, it is assumed that the security categorization of all information types associated with the information system provide an appropriate worst case potential impact for the overall information system-thereby obviating the need to consider the system processes in the security categorization of the information system.
