Security requirements

Understand the security requirements before you install IBM® Integration Bus.

The security of IBM Integration Bus components, resources, and tasks depends on the definition of users and groups configured in the operating system.

Some operating systems and other products impose restrictions on the structure and composition of user IDs:
  • On Windows systems, user IDs can be up to 12 characters long, but on Linux®, UNIX, and z/OS® systems, they are restricted to 8 characters. Database products, for example DB2®, might also restrict user IDs to 8 characters. If you have a mixed environment, ensure that the user IDs in the IBM Integration Bus environment are limited to a maximum of 8 characters.
  • Ensure that the case (upper, lower, or mixed) of user IDs in your IBM Integration Bus environment is consistent. In some environments, uppercase and lowercase user IDs are considered the same, but in other environments, user IDs of different case are considered unique. For example, on Windows the user IDs 'tester' and 'TESTER' are identical, but on Linux and UNIX systems they are recognized as different user IDs.
  • Check the validity of spaces and special characters in user IDs to ensure that, if used, these characters are accepted by all relevant systems and products in your IBM Integration Bus environment.
If your user ID does not conform to these restrictions, you might have problems with installation or verification. If so, use an alternative user ID, or create a new one, to complete installation and verification.
Understand the security requirements that are associated with the operating systems that you are using:

When you have installed IBM Integration Bus, check the Security topics in the IBM Integration Bus product documentation to review and implement the security requirements for the performance of other tasks; see Security.
