4.3.16 Restrict Access to SYSIBM.SYSMODULEAUTH

Information

The SYSIBM.SYSMODULEAUTH view contains all granted privileges on a module 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 SYSIBM tables. Therefore, it is strongly recommended to explicitly REVOKE the SELECT privilege on the SYSIBM.SYSMODULEAUTH table 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 SYSIBM.SYSMODULEAUTH FROM PUBLIC
