Network and Transport Layer Security 
Depending on the protocol used, all data (including passwords) is usually transmitted through the network (intranet or Internet) in plain text. To maintain the confidentiality of this data, you should apply transport-layer encryption for both internal communication and message exchange.
For an overview of internal communication and messaging communication, refer to Communication. For an overview of supported security mechanisms on transport level, refer to the table below.
Note
HTTP connections can be secured by using SSL (HTTPS) and RFC connections can be secured by using SNC.
