IBM MQ enables applications to read and write messages to a queue. The application that reads the message is independent of the application that writes the message. It is not a requirement to have the two applications running at the same time. If no application is available to read the message it is queued on the IBM MQ queue until an application reads it.
Non-repudiation service can be viewed as an extension to the identification and authentication service. In general, non-repudiation applies when data is transmitted electronically; for example, an order to a stock broker to buy or sell stock, or an order to a bank to transfer funds from one account to another. The overall goal of the non-repudiation service is to be able to prove that a particular message is associated with a particular individual.
In practice, proof with virtually 100% certainty, or undeniable evidence, is a difficult goal. In the real world, nothing is fully secure. Managing security is more concerned with managing risk to a level that is acceptable to the business. In su
Like MQ but where the published data can be received by multiple parties. Publish/subscribe messaging, or pub/sub messaging, is a form of asynchronous service-to-service communication used in serverless and microservices architectures. In a pub/sub model, any message published to a topic is immediately received by all of the subscribers to the topic. Pub/sub messaging can be used to enable event-driven architectures, or to decouple applications in order to increase performance, reliability and scalability.
A SOAP message is an ordinary XML document containing the following elements:
An Envelope element that identifies the XML document as a SOAP message
A Header element that contains header information
A Body element that contains call and response information
A Fault element containing errors and status information
Transport Layer Security (TLS) is a cryptographic protocol that provides secure communication between clients and servers. When a server and client communicate, TLS ensures that no third party may eavesdrop or tamper with any message.
