4.2.45 Restrict Access to SYSCAT.XSROBJECTAUTH

Information

The SYSCAT.XSROBJECTAUTH view contains granted USAGE privileges on a particular XSR object for users, groups, or roles and is read only.

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.XSROBJECTAUTH view 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.XSROBJECTAUTH FROM PUBLIC
