NIST IR 7298 Revision 1, Glossary of Key Information Security Terms Binding – An acknowledgement by a trusted third party that associates an entity’s identity with its public key. This may take place through (1) a certification authority’s generation of a public key certificate, (2) a security officer’s verification of an entity’s credentials and placement of the entity’s public key and identifier in a secure database, or (3) an analogous method. SOURCE: SP 800-21 Process of associating a specific communications terminal with a specific cryptographic key or associating two related elements of information. SOURCE: CNSSI-4009 Biometric – A physical or behavioral characteristic of a human being. SOURCE: SP 800-32 Biometric – A measurable physical characteristic or personal behavioral trait used to recognize the identity, or verify the claimed identity, of an applicant. Facial images, fingerprints, and iris scan samples are all examples of biometrics. SOURCE: FIPS 201 Biometric Information – The stored electronic information pertaining to a biometric. This information can be in terms of raw or compressed pixels or in terms of some characteristic (e.g., patterns.) SOURCE: FIPS 201 Biometric System – An automated system capable of: 1) capturing a biometric sample from an end user; 2) extracting biometric data from that sample; 3) comparing the extracted biometric data with data contained in one or more references; 4) deciding how well they match; and 5) indicating whether or not an identification or verification of identity has been achieved. SOURCE: FIPS 201 Biometrics – Measurable physical characteristics or personal behavioral traits used to identify, or verify the claimed identity, of an individual. Facial images, fingerprints, and handwriting samples are all examples of biometrics. SOURCE: CNSSI-4009 Bit – A contraction of the term Binary Digit. The smallest unit of information in a binary system of notation. SOURCE: CNSSI-4009 Pg 20
NIST IR 7298 Revision 1, Glossary of Key Information Security Terms Bit Error Rate – Ratio between the number of bits incorrectly received and the total number of bits transmitted in a telecommunications system. SOURCE: CNSSI-4009 BLACK – Designation applied to encrypted information and the information systems, the associated areas, circuits, components, and equipment processing that information. See also RED. SOURCE: CNSSI-4009 Black Box Testing – See Basic Testing. Black Core – A communication network architecture in which user data traversing a global Internet Protocol (IP) network is end-to-end encrypted at the IP layer. Related to striped core. SOURCE: CNSSI-4009 Blacklist – A list of email senders who have previously sent span to a user. SOURCE: SP 800-114 A list of discrete entities, such as hosts or applications, that have been previously determined to be associated with malicious activity. SOURCE: SP 800-94 Blacklisting – The process of the system invalidating a user ID based on the user’s inappropriate actions. A blacklisted user ID cannot be used to log on to the system, even with the correct authenticator. Blacklisting and lifting of a blacklisting are both security-relevant events. Blacklisting also applies to blocks placed against IP addresses to prevent inappropriate or unauthorized use of Internet resources. SOURCE: CNSSI-4009 Blended Attack – Malicious code that uses multiple methods to spread. SOURCE: SP 800-61 A hostile action to spread malicious code via multiple methods. SOURCE: CNSSI-4009 Blinding – Generating network traffic that is likely to trigger many alerts in a short period of time, to conceal alerts triggered by a “real” attack performed simultaneously. SOURCE: SP 800-94 Pg 21
