Does https://docs.jboss.org/author/display/AS7/Admin+Guide#AdminGuide-Messaging answer your questions?

See the 'Security settings'.

I think you need to change the role 'guest' of thist section in AS7:

<subsystem>

  <hornetq-server>

    <security-settings>

      <security-setting match="#">

        <permission type="send" roles="guest"/>

        <permission type="consume" roles="guest"/>

        <permission type="createNonDurableQueue" roles="guest"/>

        <permission type="deleteNonDurableQueue" roles="guest"/>

      </security-setting>

       </security-settings>
