The software is used to pass messages among various dissimilar networked applications. The software makes sure that messages are delivered across the network by storing them in a queue and forwarding them when networked systems are online and ready to receive the messages.
That fault-tolerant aspect of message queuing software makes it popular among large companies that transmit crucial information across networks. Banks conducting monetary transactions are a good example.
Of 50 Fortune 1,000 companies polled by Forrester for a recent study, 60 percent use messaging middleware now and 70 percent plan to within two years.
One problem with messaging middleware, such as MQSeries, is that it lacks heavy-duty security tools to protect messages broadcast over the network from being hijacked.
MQSecure adds security to MQSeries in the form of user and machine validation, to ensure that a message sent is indeed from the system or user that sent it. Also included is message validation software that makes sure messages are not intercepted and changed. Non-repudiation proves that a user actually sent a message, even if that user denies it. And encryption software from RSA Data Security makes sure that even if messages are intercepted, they appear as useless gibberish.
MQSecure is priced from $800 per network node. It works with MQSeries communications on Windows, IBM's AIX Unix, and MVS operating systems.
