1. In a communications system, the analysis of traffic rates, volumes, densities, capacities, and patterns specifically for system performance improvement. 2. The study of communications characteristics external to the text. 3. The analysis of the communications-electronic environment for use in the design, development, and operation of new communications systems. 4. In cryptology, the inference of information from observation and analysis of the presence, absence, amount, direction, and frequency of the traffic flow. 5. The Study of communications patterns. 6. The inference of information from observation of traffic flows (presence, absence, amount, direction and frequency. )

1. In a communications system or network, the protection given to information to conceal it from unauthorized persons having access to the system or network at large. Synonym segregation. 2. In a communications system, protection given to unclassified information, such as radio transmissions of law enforcement personnel, that requires safeguarding from unauthorized persons. 3. In a communications system, the protection given to prevent unauthorized disclosure of the information in the system. Note 1: The required protection may be accomplished by various means, such as by communications security measures and by directives to operating personnel. Note 2: The limited protection given certain voice and data transmissions by commercial crypto equipment is sufficient to deter a casual listener, but cannot withstand a competent cryptanalytic attack. 4. The right of individuals to control or influence what information related to them may be collected and stored and by whom and to whom that information may be disclosed. NOTE - because this term relates to the right of individuals, ii cannot be very precise and its use should be avoided except as a motivation for requiring security.

1. Abbreviation for network interface card. A network interface device (NID) in the form of a circuit card that is installed in an expansion slot of a computer to provide network access. Note: Examples of NICs are cards that interface a computer with an Ethernet LAN and cards that interface a computer with an FDDI ring network. 2. Abbreviation for network information center. An entity that provides information management, technical support, and administrative services to users of a given network. Note: NICs can form a hierarchy. A specific NIC, designated at the "Internetwork information center" or "InterNIC," has been the authority that assigns the network numbers to the subnetworks that it connects to the Internet.

1. In a communications or computer system, an arrangement of functional units according to their nature, number, and chief characteristics. Note 1: Configuration pertains to hardware, software, firmware, and documentation. Note 2: The configuration will affect system performance. 2. Selection of one of the sets of possible combinations of features of a system. 3. The selection of one of the sets of possible combinations of features of a Target of Evaluation.
Industry:Telecommunications
1. In a communications circuit, a condition in which some specified characteristic of a condition, such as a value, rate, periodicity, or amplitude, exhibits only negligible change over an arbitrarily long period. 2. In an electrical circuit, the condition that exists after all initial transients or fluctuating conditions have damped out, and all currents, voltages, or fields remain essentially constant, or oscillate uniformly. 3. In fiber optics, synonym for equilibrium mode distribution.
Industry:Telecommunications
1. Grounds for confidence that an information-technology (IT) product or system meets its security objectives. 2. In INFOSEC, see information assurance. 3. A more general term than "confidence" indicating the particular measures that can be taken to establish confidence. 4. The confidence that may be held in the security provided by a Target of Evaluation.
Industry:Telecommunications
1. For the single message format, the message words. 2. For the multiple message format, the parameter messages.
Industry:Telecommunications
1. Facts, data, or instructions in any medium or form. 2. The meaning that a human assigns to data by means of the known conventions used in their representation. 3. The meaning assigned to data by means of the convention and context used in its representation. Note: Information is represented by data and is not directly accessible except through data.
Industry:Telecommunications
1. Enciphered information. Note: Cipher text is the result obtained from enciphering plain or encoded text. 2. Data produced through the use of encipherment. The semantic content of the resulting data is not available. Note: Cipher text may itself be input to encipherment, such that super-enciphered output is produced.
Industry:Telecommunications
1. Change the security class of an object to one which does not dominate the original. 2. To change a MAC label or Information Label to a value that does not dominate the current label. Downgrade includes changing a label to value that is incomparable with the current label.
