WebSphere MQ Advanced Message Security extends WebSphere MQ to provide end-to-end message signing and encryption, including encryption of messages at rest.
WebSphere MQ AMS intercepts API calls at the application and applies encryption, and/or a digital signature prior to handing the message off to WebSphere MQ. The complementary operation is performed on the receiving side. Because the messages are encrypted while in the custody of WebSphere MQ, all ephemeral copies that WMQ makes, including transaction logs, memory, traces, etc., are also encrypted. This capability is useful for addressing compliance requirements such as PCI-DSS.
As of WebSphere MQ V7.5, AMS is built into the MQ product.
