NIST IR 7298 Revision 1, Glossary of Key Information Security Terms High Assurance Guard (HAG) – An enclave boundary protection device that controls access between a local area network that an enterprise system has a requirement to protect, and an external network that is outside the control of the enterprise system, with a high degree of assurance. SOURCE: SP 800-32 A guard that has two basic functional capabilities: a Message Guard and a Directory Guard. The Message Guard provides filter service for message traffic traversing the Guard between adjacent security domains. The Director Guard provides filter service for directory access and updates traversing the Guard between adjacent security domains. SOURCE: CNSSI-4009 High Availability – A failover feature to ensure availability during device or component interruptions. SOURCE: SP 800-113 High Impact – The loss of confidentiality, integrity, or availability that could be expected to have a severe or catastrophic adverse effect on organizational operations, organizational assets, individuals, other organizations, or the national security interests of the United States; (i.e., 1) causes a severe 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 major damage to organizational assets; 3) results in major financial loss; or 4) results in severe or catastrophic harm to individuals involving loss of life or serious life threatening injuries). SOURCE: FIPS 199; CNSSI-4009 High-Impact System – An information system in which at least one security objective (i.e., confidentiality, integrity, or availability) is assigned a FIPS 199 potential impact value of high. SOURCE: SP 800-37; SP 800-53; SP 800-60; FIPS 200 An information system in which at least one security objective (i.e., confidentiality, integrity, or availability) is assigned a potential impact value of high. SOURCE: CNSSI-4009 Honeypot – A system (e.g., a Web server) or system resource (e.g., a file on a server) that is designed to be attractive to potential crackers and intruders and has no authorized users other than its administrators. SOURCE: CNSSI-4009 Pg 84
NIST IR 7298 Revision 1, Glossary of Key Information Security Terms Hot Site – A fully operational offsite data processing facility equipped with hardware and software, to be used in the event of an information system disruption. SOURCE: SP 800-34 Backup site that includes phone systems with the phone lines already connected. Networks will also be in place, with any necessary routers and switches plugged in and turned on. Desks will have desktop PCs installed and waiting, and server areas will be replete with the necessary hardware to support business-critical functions. Within a few hours, a hot site can become a fully functioning element of an organization. SOURCE: CNSSI-4009 Hot Wash – A debrief conducted immediately after an exercise or test with the staff and participants. SOURCE: SP 800-84 Hybrid Security Control – A security control that is implemented in an information system in part as a common control and in part as a system-specific control. See also Common Control and System-Specific Control. SOURCE: SP 800-37; SP 800-53; SP 800-53A; CNSSI-4009 IA Architecture – A description of the structure and behavior for an enterprise’s security processes, information security systems, personnel and organizational sub-units, showing their alignment with the enterprise’s mission and strategic plans. SOURCE: CNSSI-4009 IA Infrastructure – The underlying security framework that lies beyond an enterprise’s defined boundary, but supports its IA and IA-enabled products, its security posture and its risk management plan. SOURCE: CNSSI-4009 IA Product – Product whose primary purpose is to provide security services (e.g., confidentiality, authentication, integrity, access control, nonrepudiation of data); correct known vulnerabilities; and/or provide layered defense against various categories of non-authorized or malicious penetrations of information systems or networks.
