Security properties

The level of queue-based security to be used is determined through the setting of attributes on queues. As a consequence of these attributes, MQe uses, if required, appropriate secure channels, cryptors, and compressors, and controls access through authenticators.

The relevant queue properties are:

Compressor
A compressor is optional. It determines whether the data should be compressed.
Cryptor
A cryptor is optional. It determines whether the data should be encrypted to hide the significance of the contents.
Authenticator
An authenticator is optional. It determines whether the data access should be controlled.
Attribute rule
An attribute rule is optional in the sense that you can specify a null for this property. If a null is specified, a system default attribute rule is then used internally. An attribute rule determines whether an existing channel can be reused or upgraded to access a particular queue.

If either a cryptor or authenticator has been specified, the QueueManager must have a private registry defined. The only exception to this requirement is when using remote synchronous queues.
