# SSL

You can use SSL to secure communication between a pair of fault-tolerant servers.

Parameters in the main configuration file (tibemsd.conf) affect this behavior. The relevant parameters all begin with the prefix ft_ssl.

The server initializing a secure connection to another server uses the `ft_ssl` parameters to determine the properties of its secure connection to the other server. The receiving server validates the incoming connection against its own `ssl_ parameters`. For more information about `ft_ssl` parameters, see Fault Tolerance Parameters. For more information about `ssl_ parameters`, see SSL Server Parameters.
