 Coloured Book protocols

Coloured Book protocols refer to a set of communication protocols developed for computer networking and telecommunications, primarily in the context of the British government's "Coloured Book" standards. These protocols were designed to facilitate secure and reliable data exchange over networks, particularly in environments where security and confidentiality were critical. The term "Coloured Book" comes from the practice of using different colors for various protocol specifications. Each "color" would represent a different set of requirements or security levels.
