## Securing Communication Channels

### Use

Data is transferred via the following communication channels, among others:

Communication Channels

From | To | Protocol
MaxDB X Server | MaxDB client (database tool, interface) | TCP/IP Optional: SSL (only in SAP systems)
MaxDB X Server | SAProuter | NI (SAP protocol) Optional: NISSL (only in SAP systems)

### Procedure

In SAP systems you can encrypt a data transfer to ensure that no data is intercepted during transfer between two computers.

For more information, see the Installation Guide for your SAP system; see SAP note 767598.

When logging onto a database instance, the user's password is encrypted rather than being transferred in plain text. See Concepts of the Database System, Authentication.
