To have Web-based System Manager operate in a secure mode (using SSL Sockets that encrypt data transmitted over the network), the sysmgt.websm.security fileset must be installed on the server and security must be configured on both client and server machines.
For 128-bit encryption of data sent over the network, the sysmgt.websm.security-us fileset must be installed in addition to the sysmgt.websm.security file set. Configuration is discussed in detail in Securing Web-based System Manager.
