Maintaining Security As new users are added to your system, you will need to grant authorities to them as needed. You must also add new users to appropriate groups. Conversely, when users leave your system, their authorities should be revoked, and they should be removed from all authorization groups. Use the GRANT and REVOKE statements to add or remove authorities. These statements perform simple maintenance operations that do not affect table data. Whenever possible, it is recommended that you grant authorities to groups rather than individuals. This simplifies the task of maintenance, since you only need to add or delete a name rather than granting or revoking an entire set of authorities. You can use simple maintenance operations to change the characteristics of authorization groups. Use the ADD and REMOVE statements to add or remove an individual or group. Use the GRANT and REVOKE statements to change the authorizations given to the group.
