You should configure the toolbar to the set of features tat will produce tags that you are comfortable with.
If you want to enforce the tags limitation, you should never rely on anything on the browser for that. It is quite easy to bypass the editor and send any kind of content to your server. You should instead make all cleanup and checks in the server side when receiving the editor data.
