with the rise of asynchronous messaging comes the need for securing message flows in websphere mq. this article discusses the architecture of websphere mq, along with some options available for securing an asynchronous communications infrastructure.
todays business environment is becoming more and more complex, and the demands on the it department to support increasing numbers of enterprise initiatives are growing in lockstep. one area drawing significant attention is communications, both between applications within the enterprise and between applications that span companies. while communications over the internet have traditionally been characterized in terms of http (browser/web server, and more recently, web applications running over soap), other communication styles are often more efficient and/or more appropriate.
asynchronous messaging is a popular and effective communications paradigm for integrating applications within the enterprise as well as facilitating electronic business relationships that span enterprise boundaries. nevertheless, as with all forms of communications (see sidebar on xml), security is the critical requirement - and the level of trust that can be established is often the major determinant of the business value the integration returns to the enterprise.
in this article i will describe the integration of x.509 digital certificates and messaging to create a trustworthy mechanism for the exchange of sensitive business information. in particular, i will describe in some detail the architecture of ibms websphere mq (formerly known as mqseries), with an emphasis on the options for securing message flows using capabilities enabled by aspects of verisign intelligence and control services - public key cryptography, digital certificates, and public key infrastructure (pki).
