NIST IR 7298 Revision 1, Glossary of Key Information Security Terms Security Assertion Markup Language (SAML) – A specification for encoding security assertions in the Extensible Markup Language (XML). SOURCE: SP 800-63 A framework for exchanging authentication and authorization information. Security typically involves checking the credentials presented by a party for authentication and authorization. SAML standardizes the representation of these credentials in an XML format called “assertions,” enhancing the interoperability between disparate applications. SOURCE: SP 800-95 A protocol consisting of XML-based request and response message formats for exchanging security information, expressed in the form of assertions about subjects, between online business partners. SOURCE: CNSSI-4009 Security Association – A relationship established between two or more entities to enable them to protect data they exchange. SOURCE: CNSSI-4009 Security Attribute – A security-related quality of an object. Security attributes may be represented as hierarchical levels, bits in a bit map, or numbers. Compartments, caveats, and release markings are examples of security attributes. SOURCE: FIPS 188 An abstraction representing the basic properties or characteristics of an entity with respect to safeguarding information; typically associated with internal data structures (e.g., records, buffers, files) within the information system which are used to enable the implementation of access control and flow control policies; reflect special dissemination, handling, or distribution instructions; or support other aspects of the information security policy. SOURCE: SP 800-53; CNSSI-4009 Security Authorization – See Authorization. Security Authorization – (To Operate) See Authorization (to operate). SOURCE: CNSSI-4009 Security Authorization Boundary – See Authorization Boundary. Pg 168
NIST IR 7298 Revision 1, Glossary of Key Information Security Terms Security Banner – A banner at the top or bottom of a computer screen that states the overall classification of the system in large, bold type. Also can refer to the opening screen that informs users of the security implications of accessing a computer resource. SOURCE: CNSSI-4009 Security Categorization – The process of determining the security category for information or an information system. See Security Category. SOURCE: SP 800-53 Security Category – Security Concept of Operations – (Security CONOP) Security Content Automation Protocol (SCAP) – The process of determining the security category for information or an information system. Security categorization methodologies are described in CNSS Instruction 1253 for national security systems and in FIPS 199 for other than national security systems. SOURCE: SP 800-37; SP 800-53A The characterization of information or an information system based on an assessment of the potential impact that a loss of confidentiality, integrity, or availability of such information or information system would have on organizational operations, organizational assets, or individuals. SOURCE: FIPS 200; FIPS 199; SP 800-18 The characterization of information or an information system based on an assessment of the potential impact that a loss of confidentiality, integrity, or availability of such information or information system would have on organizational operations, organizational assets, individuals, other organizations, and the Nation. SOURCE: SP 800-53; CNSSI-4009; SP 800-60 A security-focused description of an information system, its operational policies, classes of users, interactions between the system and its users, and the system’s contribution to the operational mission. SOURCE: CNSSI-4009 A method for using specific standardized testing methods to enable automated vulnerability management, measurement, and policy compliance evaluation against a standardized set of security requirements. SOURCE: CNSSI-4009 Pg 169
