better to just explicitly grant access, rather than allow the implicit access to apply. Queue security Profiles in the mqqueue class control access to queues. Whether or not a message is persistent is always important. DeveloperWorks WebSphere weekly newsletter The developerWorks newsletter gives you the latest articles and information only on those topics that interest you. Or, you might want to have one scheme for protecting commands for test and other non-production queue managers, and a second more restrictive scheme to protect commands on your production queue managers. For additional information, see the topic "Publish/subscribe security" in the WebSphere MQ V7 information center. WebSphere MQ public newsgroup A non-IBM forum where you can get answers to your WebSphere MQ technical questions and share your WebSphere MQ knowledge with other users. Connection security is a simple binary setting: either a user can connect to the queue manager, or they cannot. Therefore the authority to define published
a qalias can allow a user to bypass security, and only the most trusted administrators should be permitted to define or alter a qalias. Since the authorization to set context allows the user to override the UserIdentifier, if you are using any feature that relies on the UserIdentifier, be careful about granting set authority. For example, userid robert1 issues this command to define alias queue IAS: Example. You can do so by limiting access to the commands that can affect them, and also through command resource security. For example, for cics, the access that the cics region userid has to reslevel determines if one, two, or even no userids will be checked for access to WebSphere MQ resources. Type of resource protected, upper case class, upper case group class. These are the profiles that control what can or cannot be done through the MQI. IN applies to access by the channel initiator. Because of the widespread use of the term persistent queue and an incorrect belief about behavior of the queue based on that, some customers find that WMQ doesnt behave as they expect, often to their detriment. Security for queue context - beyond that for PUT - depends on whether you will use UserIdentifier or other fields in the context part of the message descriptor. Even though the default is to deny access, it is a common practice to define a backstop profile such as CSQ1.* in the mqqueue class. The second category, resources that you define locally, includes things like application queues, channels, and topics. Sessions range from one-hour Webcasts to half-day and full-day live sessions in cities worldwide. Once you have documented your security requirements, then you can start designing profiles to best secure your queue managers and their application messages. You cannot determine the effect of mxtopic profiles on topic security just by reviewing the profiles themselves. Since these are either critical infrastructure, or models that provide defaults for the resources defined for your applications, you need to protect them. But I am not clever, so I would prefer to make a macro of some sorts, which could rename and copy the little buggers. As an example, if commands are left unprotected, then queues cannot be secure because if anyone can define a qalias, they can use the qalias to bypass queue security. (One exception is if the queue manager is in a QSG.

You can set it new school writing to upper the default or mixed to control whether the queue manager will use upper or mixed case racf classes. That are defined in classes, training information, backstop profiles Before considering profiles for system and application resources. That is, define a backstop profile ER, see the product documentation for additional guidance.

And other events around the world of interest to WebSphere developers. Topicstr, or hopefully the application explicitly set the persistence that was required. Topic objects and the racf profiles that match them secure topic trees. Much of the article WebSphere MQ for zOS security is about channel security.
