Message Queue Access Controls

Identity Synchronization for Windows uses Message Queue’s access control to prevent unauthorized access to message subscription and publishing, allowing each connector to trust messages that it receives.

Unique username and passwords known only to Message Queue and to the connector are provided to access the Message Queue broker. Each message sent over the Message Queue is encrypted with a per topic 3DES key, which protects the message contents and prevents outsiders who do not know the topic key from sending meaningful messages. These measures prevent (a) an attacker from sending falsified password synchronization messages to connectors and (b) an attacker from impersonating a connector and receiving actual password updates.

Note –

By default, clients of the Message Queue, such as the connectors and system manager, accept any SSL certificate that the Message Queue broker returns. See Hardening Your Security for more information to enhance Message Queue certificate validation and other Message Queue-related security issues.
