DUS primarily is a O&D-airport, not a transfer airport (even though airlines and the airport itself like to market that).
Allow 90 minutes for the connection and you are safe in case of minor delays.
As long as the bags are checked-thru to DRS
there is no need (and option) to retrieve them at DUS
, this will be dealt with at DRS
Just clear immigration and a new security check at DUS
