In order to see what Response Rules are applied to a specific policy, you are required to either (a) open each policy, click on the response tab or (b) get into each response rule and see which policies are setup to use 'this' response rule.
It would be a great feature, if we can see the response rules part of the main policies page (under Manage, Policies & Policy List).
There are some security solutions which even provides drop downs for reponse rules which could be edited on the fly, from tthe main screen itself. This would really save a lot of effort & time for DLP Administrators as a whole
