Network Security 
The
SAP Mobile Infrastructure uses the Hypertext
Transfer Protocol (HTTP) or Secure Hypertext Transmission Protocol (HTTPS) for
communications between the mobile device and the server. Secure Sockets Layer
(SSL) should be used for data transfer, see
Setting Secure Sockets
Layer (SSL) Support.
The components only transfer data if the user of the device was identified by the SAP MI Server Component, that is if there is a valid user on the server. The user must also be authorized to synchronize data (S_ME_SYNC).
For
detailed information about network security see the
SAP NetWeaver Security
Guide.
