4.2.43 Restrict Access to SYSCAT.WORKLOADAUTH

Information

The SYSCAT.WORKLOADAUTH view represents the users, groups, or roles that have been granted the USAGE privilege on a workload.

Rationale:

Any databases created without the RESTRICT option automatically GRANT the SELECT privilege to PUBLIC for SYSCAT views. Therefore, it is strongly recommended to explicitly REVOKE the SELECT privilege on the SYSCAT.WORKLOADAUTH from PUBLIC to reduce risk to the organization's data.

Solution

Perform the following to revoke access from PUBLIC.

Connect to the Db2 database.

db2 => connect to <dbname>

Run the following command:

db2 => REVOKE SELECT ON SYSCAT.WORKLOADAUTH FROM PUBLIC
