Changing the Default for Communication Protocols

A description of how to change the default for communication protocols. Sybase CEP enables you to restrict the SSL protocols negotiated on a secure connection to only the ones you specify.

You can restrict permitted protocols to SSL2, SSL3, or TLS. To change the default communication protocol that the SSL client uses to communicate with the SSL server, add the following line to the client's preferences file. For Sybase CEP Studio, this file is called studio-preferences.xml, and is located in the SybaseC8Repository:

<preference name="SybaseC8/Security/SSL/UseProtocol" 
  value="
comma-separated-list-of-allowed-communication-protocols
"/>

To restrict the communication protocols negotiated by the SSL server when communicating with the SSL client, set the "AcceptProtocol" preference in the server's c8-server.conf file to a comma-separated list of the communication protocols you want the server to accept. If this preference is omitted, or left blank, then all permitted communication protocols are negotiated.
