Description

 The objective is to range concise query from the user to maximize the efficiency of the objective is to protect private networks by firewall and depends on quality of policies.  Many firewall policies are adopts technology to secure private networks.  The Proposed mechanism for systematic structural testing of firewall policies are based on coverage criteria of rules, predicates and clauses.  To attain elevated structural coverage efficiently, we have deployed four automated packet generation techniques: The Random packet generation, local constraint, and global constraint and boundary values.  The experimental results on set of real policies and a set of faulty policies to detect the faults with generated packet sets.  Our proposed mechanism proved that the most fault detections are higher structural coverage.
