You can take steps to secure your environment when you augment the WebSphere Application Server for z/OS default profile with WebSphere® ESB security profile data. Alternatively you can provide the same information on the administrative console after you augment the profile.
When you configure WebSphere ESB there are several response file properties representing components, where you can enter user names and passwords for security purposes. The three components of WebSphere ESB that permit you to enter these user names and passwords are the Service Component Architecture (SCA), Business Process Choreographer, and the Common Event Infrastructure (CEI).
These user names and passwords are used to create authentication aliases and are required when you enable security. If you do not enter the user names and passwords when you configure WebSphere ESB, you can provide the same information using the administrative console, after you have configured the WebSphere ESB.
You must hold the edited response files in a secure location because the user names and passwords are stored in plain text.
More information about managing authentication aliases is provided in subsequent topics.
