4.3.24 Restrict Access to SYSIBM.ROUTINES_S

Information

The SYSIBM.ROUTINES_S view contains user-defined routines (scalar function, table function, sourced function, aggregate interface function, method, or procedure). It is recommended that the PUBLIC role be restricted from accessing this view.

Rationale:

Any databases created without the RESTRICT option automatically GRANT the SELECT privilege to PUBLIC for SYSIBM views. Therefore, it is strongly recommended to explicitly REVOKE the SELECT privilege on the SYSIBM.ROUTINES_S 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 SYSIBM.ROUTINES_S FROM PUBLIC
