The queue manager fully supports the security functions supplied with WebSphere MQ Everyplace. Any messages stored in a queue defined with security characteristics are encoded using those characteristics. Any communication connections set up between a queue manager and a secure queue use the security characteristics of the queue, or an existing connections with equal or higher security.
Messages can be individually protected by attaching security characteristics to them directly. The correct characteristics must be presented whenever dealing with a message protected in this manner.
See Security for a detailed discussion of WebSphere MQ Everyplace security.
