NIST IR 7298 Revision 1, Glossary of Key Information Security Terms Interface – Common boundary between independent systems or modules where interactions take place. SOURCE: CNSSI-4009 Interface Control Document – Technical document describing interface controls and identifying the authorities and responsibilities for ensuring the operation of such controls. This document is baselined during the preliminary design review and is maintained throughout the information system life cycle. SOURCE: CNSSI-4009 Interim Approval to Operate – (IATO) Interim Approval to Test (IATT) – Intermediate Certification Authority (CA) – Temporary authorization granted by a DAA for an information system to process information based on preliminary results of a security evaluation of the system. (To be replaced by ATO and POA&M) SOURCE: CNSSI-4009 Temporary authorization to test an information system in a specified operational information environment within the time frame and under the conditions or constraints enumerated in the written authorization. SOURCE: CNSSI-4009 A Certification Authority that is subordinate to another CA, and has a CA subordinate to itself. SOURCE: SP 800-32 Internal Network – A network where: (i) the establishment, maintenance, and provisioning of security controls are under the direct control of organizational employees or contractors; or (ii) cryptographic encapsulation or similar security technology provides the same effect. An internal network is typically organization-owned, yet may be organization-controlled while not being organization-owned. SOURCE: SP 800-53 A network where 1) the establishment, maintenance, and provisioning of security controls are under the direct control of organizational employees or contractors; or 2) cryptographic encapsulation or similar security technology implemented between organization-controlled endpoints provides the same effect (at least with regard to confidentiality and integrity). An internal network is typically organization-owned, yet may be organization-controlled while not being organization-owned. SOURCE: CNSSI-4009 Pg 100
NIST IR 7298 Revision 1, Glossary of Key Information Security Terms Internal Security Controls – Hardware, firmware, or software features within an information system that restrict access to resources only to authorized subjects. SOURCE: CNSSI-4009 Internal Security Testing – Security testing conducted from inside the organization’s security perimeter. SOURCE: SP 800-115 Internet – The Internet is the single, interconnected, worldwide system of commercial, governmental, educational, and other computer networks that share (a) the protocol suite specified by the Internet Architecture Board (IAB), and (b) the name and address spaces managed by the Internet Corporation for Assigned Names and Numbers (ICANN). SOURCE: CNSSI-4009 Internet Protocol (IP) – Standard protocol for transmission of data from source to destinations in packet-switched communications networks and interconnected systems of such networks. SOURCE: CNSSI-4009 Interoperability – For the purposes of this standard, interoperability allows any government facility or information system, regardless of the PIV Issuer, to verify a cardholder’s identity using the credentials on the PIV Card. SOURCE: FIPS 201 Interview – A type of assessment method that is characterized by the process of conducting discussions with individuals or groups within an organization to facilitate understanding, achieve clarification, or lead to the location of evidence, the results of which are used to support the determination of security control effectiveness over time. SOURCE: SP 800-53A Intranet – A private network that is employed within the confines of a given enterprise (e.g., internal to a business or agency). SOURCE: CNSSI-4009 Intrusion – Unauthorized act of bypassing the security mechanisms of a system. SOURCE: CNSSI-4009 Pg 101
