User authorization for IBM Streams

IBM® Streams uses access control lists (ACLs) to manage user authorization for domains and instances. An ACL contains the type of domain and instance objects to secure and the actions that a user or group is authorized to perform against the object. The ACLs are initialized when you create a domain or instance.

Security objects and access permissions for IBM Streams domains and instances
IBM Streams security objects and permissions enable you to control access to domain and instance resources and data. You can update security objects and access permissions by using the Streams Console or streamtool commands.
Roles
A role is a collection of permissions that can be assigned to a user or group of users.
Job groups
A job group is a group of jobs that have the same authority or permissions.
Viewing and configuring ACL settings for IBM Streams domains and instances
You can review and configure the access control list (ACL) settings for IBM Streams domains and instances by using the streamtool command-line interface. You can also grant access privileges to domain and instance resources by using the Streams Console.
Configuring user access to IBM Streams domains and instances
By default, IBM Streams domains and instances are private and can be accessed only by the user who creates the domain or instance. To set up a domain or instance that can be accessed by multiple users, you can use either the IBM Streams graphical user interfaces or streamtool commands.
