NIST IR 7298 Revision 1, Glossary of Key Information Security Terms Minor Application – An application, other than a major application, that requires attention to security due to the risk and magnitude of harm resulting from the loss, misuse, or unauthorized access to or modification of the information in the application. Minor applications are typically included as part of a general support system. SOURCE: SP 800-18 Misnamed Files – A technique used to disguise a file’s content by changing the file’s name to something innocuous or altering its extension to a different type of file, forcing the examiner to identify the files by file signature versus file extension. SOURCE: SP 800-72; CNSSI-4009 Mission Assurance Category – (MAC) A Department of Defense Information Assurance Certification and Accreditation Process (DIACAP) term primarily used to determine the requirements for availability and integrity. SOURCE: CNSSI-4009 Mission Critical – Any telecommunications or information system that is defined as a national security system (Federal Information Security Management Act of 2002 - FISMA) or processes any information the loss, misuse, disclosure, or unauthorized access to or modification of, would have a debilitating impact on the mission of an agency. SOURCE: SP 800-60 Mobile Code – Software programs or parts of programs obtained from remote information systems, transmitted across a network, and executed on a local information system without explicit installation or execution by the recipient. SOURCE: SP 800-53; SP 800-18 A program (e.g., script, macro, or other portable instruction) that can be shipped unchanged to a heterogeneous collection of platforms and executed with identical semantics. SOURCE: SP 800-28 Software programs or parts of programs obtained from remote information systems, transmitted across a network, and executed on a local information system without explicit installation or execution by the recipient. Note: Some examples of software technologies that provide the mechanisms for the production and use of mobile code include Java, JavaScript, ActiveX, VBScript, etc. SOURCE: CNSSI-4009 Pg 120
NIST IR 7298 Revision 1, Glossary of Key Information Security Terms Mobile Code Technologies – Software technologies that provide the mechanisms for the production and use of mobile code (e.g., Java, JavaScript, ActiveX, VBScript). SOURCE: SP 800-53; SP 800-18 Mobile Device – Portable cartridge/disk-based, removable storage media (e.g., floppy disks, compact disks, USB flash drives, external hard drives, and other flash memory cards/drives that contain nonvolatile memory). Portable computing and communications device with information storage capability (e.g., notebook/laptop computers, personal digital assistants, cellular telephones, digital cameras, and audio recording devices). SOURCE: SP 800-53 Mobile Software Agent – Programs that are goal-directed and capable of suspending their execution on one platform and moving to another platform where they resume execution. SOURCE: SP 800-19 Mode of Operation – An algorithm for the cryptographic transformation of data that features a symmetric key block cipher algorithm. SOURCE: SP 800-38C Description of the conditions under which an information system operates based on the sensitivity of information processed and the clearance levels, formal access approvals, and need-to-know of its users. Four modes of operation are authorized for processing or transmitting information: dedicated mode, system high mode, compartmented/partitioned mode, and multilevel mode. SOURCE: CNSSI-4009 Moderate Impact – The loss of confidentiality, integrity, or availability that could be expected to have a serious adverse effect on organizational operations, organizational assets, individuals, other organizations, or the national security interests of the United States; (i.e., 1) causes a significant degradation in mission capability to an extent and duration that the organization is able to perform its primary functions, but the effectiveness of the functions is significantly reduced; 2) results in significant damage to organizational assets; 3) results in significant financial loss; or 4) results in significant harm to individuals that does not involve loss of life or serious life threatening injuries).
