Communication between the Sun Management Center server layer and clients such as consoles and command-line interfaces is performed using Java Technology Remote Method Invocation (RMI) in conjunction with a comprehensive product-specific security model. The security model allows clients to operate in either low, medium or high security modes, which affects the level of message authentication that is performed.
Low: No message authentication. Only the user password is checked at time of login.
Medium (default): Console-to-server authentication only, for example, server authentication of incoming console messages.
High: Both console and server authenticate messages.
Because of the potential performance impact of the higher security levels, you should carefully consider your message authentication requirements.
