Hi
As I know about the Dshield object, we need to create a rule in the rulebase as given below:
Source:Dshield Object
Dest:Your network
action: drop
Log: enabled

Storm Center is the organisation that has the black listed IP's and it helps to block the attacks to your network.Also you need to send the logs to Storm Center so that they can get more information about the blacklisted IP's.

I hope this will help you.

Regards
