Preventing the CAE server from opening RC4 sockets

By default, when communicating with CAE agents, the CAE server attempts to listen for connections from CAE agents using both RC4 and TLS sockets. To enhance security, if you have configured the use of AT-TLS for all your CAE agents, you can prevent the CAE server from opening RC4 sockets.

Procedure

To prevent the CAE server from opening RC4 sockets, edit your CAE server properties file as follows:
  • If the CAE server is installed on Windows, edit cqm.server.properties to specify the parameter com.rocketsoft.nm.qm.caeAgent.rc4ProtocolEnabled=false. If a cqm.server.properties file does not exist, create one.
  • If the CAE server is installed on USS, edit the CAE server started task CQMCAESV DD to specify the parameter RC4_PROTOCOL_ENABLED=false.
