Assured Channel - A network communication link that is protected by a security protocol providing authentication, confidentiality, and data integrity, and employs U.S. Government- approved cryptographic technologies whenever cryptographic means are utilized. The following protocols and mechanisms are sufficient to meet the requirements for an assured channel carrying unclassified data: [[Term:Internet Protocol Security | [[Term:Internet Protocol | Internet Protocol]] Security]], Secure Sockets Layer v3, Transport Layer Security, and Secure Multipurpose Internet Mail Extension. Assured channels for classified data must use an NSA- approved protection mechanism commensurate with the classification level of the data. E2.1.1.
Assured Channel - A network communication link that is protected by a security protocol providing authentication and data integrity, and employs cryptographic technologies approved by the U.S. Government (USG) whenever cryptographic means are used. Examples of protocols and mechanisms that may be used to provide authentication and data integrity protection for an assured channel include [[Term:Internet Protocol Security | [[Term:Internet Protocol | Internet Protocol]] Security]] (IPSec), Secure Sockets Layer (SSL), Transport Layer Security (TLS), digital code signing using a trusted code-signing certificate, and other systems using NSA- approved high assurance guards with link encryption methodology.
