The process of scheduling involves the sending and receiving of scheduling messages. As a result, the security problems related to messaging in general are relevant here. In particular, the authenticity of the scheduling messages needs to be verified. Servers and clients MUST use an HTTP connection protected with Transport Layer Security (TLS) as defined in [RFC2818] for all scheduling operations. Clients MUST use the procedures detailed in Section 6 of [RFC6125] to verify the authenticity of the server. Servers MUST make use of HTTP authentication [RFC2617] to verify the authenticity of the calendar user for whom the client is sending requests.
