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.
