Runtime resources are WebSphere Business Integration Message Broker objects that exist at run time. Runtime security controls your permission to take actions on those resources from the workbench. For example, the user ID that you use to deploy a message flow to an execution group must have permission to take that deploy action.
In WebSphere Business Integration Message Broker, each runtime object has an Access Control List (ACL). The ACL for an object determines the view and modify permissions that a principal has for that object. ACLs provide more granularity and give you a greater degree of control over the permissions that principals have. ACLs also enable a single Configuration Manager in a single security domain to control brokers with incompatible access control, such as development, system test, and production.
WebSphere Business Integration Message Broker allows you to control access by object as opposed to by group. For example, user JUNGLE\MPERRY might be given access to modify BROKERA, but have no access rights to BROKERB. In a further example the same user might have access to deploy to execution group EXEGRP1, but not to EXEGRP2, even though they are both members of BROKERA.
Access level control is based on the operation requested on any type of WebSphere Business Integration Message Broker object, for example, brokers and execution groups. Access control enables permission assignment to principals (users and groups), and these permissions specify view and modify rights for deployment configuration resources. In WebSphere Business Integration Message Broker, administrators can configure ACLs to use their organization's principals.
This model provides full object level access based on the action that needs to be performed, provided the necessary group and access entry has been created, and the system administrator can nest local and domain groups to help organize security requirements and users.
You can still operate with any existing group level security environments from earlier releases of WebSphere Business Integration Message Broker without any migration issues. If you have any existing user role definition groups with members, you can continue to use this model without making any additional changes. The object level security model is only invoked if the user role definition groups are either empty or do not exist. If you want to implement object level security, you must ensure that the user role definition groups are empty.
The Configuration Manager checks the user role definition groups (mqbrops) to obtain permission for your user ID to perform the requested action on the object type. If permission cannot be granted using these groups, the Configuration Manager checks the ACL table. If your user ID is included in the ACL for the named object, or is a member of a Windows group that has the required access to the named object, you have permission to perform the operation.
