4.2.20 Restrict Access to SYSCAT.ROLEAUTH

Information

The SYSCAT.ROLEAUTH view contains information on all roles and their respective grantees. It is recommended that the PUBLIC role be restricted from accessing this view.

Rationale:

PUBLIC should not have access to see the grants of the roles because this could be used as a point of exploit.

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.ROLEAUTH FROM PUBLIC
