4.2.22 Restrict Access to SYSCAT.ROUTINEAUTH

Information

The SYSCAT.ROUTINEAUTH view contains a list of all users that have EXECUTE privilege on a routine (function, method, or procedure). It is recommended that the PUBLIC role be restricted from accessing this view.

Rationale:

PUBLIC should not have access to see all the users 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.ROUTINEAUTH FROM PUBLIC
