HTTPS is the typical way to go when securing network communications, but for more elaborate architectures securing the actual payload is often also a necessity. Jean-Francois Denise explains how to take this road using WS-Security in JMX.
Basic Authentication and HTTPS are the basic building blocks on which you can rely to secure remote WS access to your JMX instrumentation. These technologies are very commonly used and are simple to put in place when you need point-to-point security. For more complex architectures, however, where messages contexts contain multiple nodes, HTTPS is not the best solution. Due to the huge number of alternatives you can use when trying to secure your communications, you will generally run into interoperability problems. WS-Security has been designed to offer interoperability while still allowing you to plug in various technologies. The WSIT project on java.net (JavaOne 2007 Technical Session TS-4865 offers a good introduction to WSIT) offers an interoperable WS-* stack that, along with a full set of other WS standards, integrates a Java technology implementation of WS-Security. WSIT is the solution I have adopted to plug WS-Security into the Connector.
