NIST IR 7298 Revision 1, Glossary of Key Information Security Terms Syllabary – List of individual letters, combination of letters, or syllables, with their equivalent code groups, used for spelling out words or proper names not present in the vocabulary of a code. A syllabary may also be a spelling table. SOURCE: CNSSI-4009 Symmetric Encryption Algorithm – Encryption algorithms using the same secret key for encryption and decryption. SOURCE: SP 800-49; CNSSI-4009 Symmetric Key – A cryptographic key that is used to perform both the cryptographic operation and its inverse, for example to encrypt and decrypt, or create a message authentication code and to verify the code. SOURCE: SP 800-63; CNSSI-4009 Symmetric Key – A single cryptographic key that is used with a secret (symmetric) key algorithm. SOURCE: SP 800-21 [2 nd Ed] Synchronous Crypto-Operation – Encryption algorithms using the same secret key for encryption and decryption. SOURCE: CNSSI-4009 System – See Information System. Any organized assembly of resources and procedures united and regulated by interaction or interdependence to accomplish a set of specific functions. See also information system. SOURCE: CNSSI-4009 System Administrator – A person who manages the technical aspects of a system. SOURCE: SP 800-40 Individual responsible for the installation and maintenance of an information system, providing effective information system utilization, adequate security parameters, and sound implementation of established Information Assurance policy and procedures. SOURCE: CNSSI-4009 System Assets – Any software, hardware, data, administrative, physical, communications, or personnel resource within an information system. SOURCE: CNSSI-4009 Pg 186
NIST IR 7298 Revision 1, Glossary of Key Information Security Terms System Development Life Cycle – (SDLC) System Development Methodologies – The scope of activities associated with a system, encompassing the system’s initiation, development and acquisition, implementation, operation and maintenance, and ultimately its disposal that instigates another system initiation. SOURCE: SP 800-34; CNSSI-4009 Methodologies developed through software engineering to manage the complexity of system development. Development methodologies include software engineering aids and high-level design analysis tools. SOURCE: CNSSI-4009 System High – Highest security level supported by an information system. SOURCE: CNSSI-4009 System High Mode – Information systems security mode of operation wherein each user, with direct or indirect access to the information system, its peripherals, remote terminals, or remote hosts, has all of the following: a. valid security clearance for all information within an information system; b. formal access approval and signed nondisclosure agreements for all the information stored and/or processed (including all compartments, subcompartments and/or special access programs); and c. valid need-to-know for some of the information contained within the information system. SOURCE: CNSSI-4009 System Indicator – Symbol or group of symbols in an off-line encrypted message identifying the specific cryptosystem or key used in the encryption. SOURCE: CNSSI-4009 System Integrity – The quality that a system has when it performs its intended function in an unimpaired manner, free from unauthorized manipulation of the system, whether intentional or accidental. SOURCE: SP 800-27 Attribute of an information system when it performs its intended function in an unimpaired manner, free from deliberate or inadvertent unauthorized manipulation of the system. SOURCE: CNSSI-4009 System Interconnection – The direct connection of two or more IT systems for the purpose of sharing data and other information resources. SOURCE: SP 800-47; CNSSI-4009 System Low – Lowest security level supported by an information system. SOURCE: CNSSI-4009 Pg 187
