(a)-(b)  The confidentiality of Cabinet documents, discussions and decisions is a long established principle and has been regarded as essential for the maintenance of Cabinet collective responsibility, although these principles are tempered by the requirement for consultation and the dissemination of Cabinet information.
The Department has previously advised Ministers in successive Governments that SMS messaging services are not a secure communication channel and should not be used to convey or transfer information, which is sensitive or confidential in nature. Other secure messaging services, such as iMessage or WhatsApp have not undergone a security risk assessment as yet and have not been endorsed for use to convey or transfer information which is of sensitive or confidential in nature.
