The extended study of this research leads to the grouping of firewalls which could be capable of providing security at distributed points. Firewall allows separation between frontend and backend entity so as to ensure security. Various other entities like DPFF needs to be protected from outsiders (unauthorized users).To do so firstly, firewall policies needs to be tested because most of the policies have been corrupted or plagued with policy faults which may leads to trafficking. During Firewall working mechanism, DPFF layers themselves act as layers of protection or defence using various policies and algorithms which help in reducing the traffic and making the efficiency in detection and policy updating. The complete frame work signifies a distributed firewall and its testing policies to ensure network security.
