This paper describes the information security attributes of confidentiality, integrity and availability, and then uses these to determine the security requirements for ETP. It briefly describes the four published UK ETP models (from Flexiscript, Phamacy2U, Salford and Transcript) and evaluates these from the perspectives of confidentiality, integrity and availability. Deficiencies, from a security perspective, in the 3 UK ETP pilot models (from Flexiscript, Phamacy2U, and Transcript) are described. Possible solutions to these deficiencies, as implemented in the Salford model, are described. |
