Guidelines for the Selection and Use of Transport Layer Security (TLS) Implementations



C M. Chernick, Charles Edington III, Matthew J. Fanto, R Rosenthal


[WITHDRAWN 3/13/13. Superseded by SP 800-52 Rev. 1 (April 2014):] These Guidelines briefly introduce computer communications architectural concepts. The Guidelines place the responsibility for communication security at the Transport layer of the OSI seven-layer communications stack, not within the application itself. Protection of sensitive but unclassified Government information can adequately be accomplished at this layer when appropriate protocol options are selected and used by clients and servers relying on transport layer security.
