1. A method for testing a firewall, the method comprising: applying, by the traffic management computing device, an enforced firewall policy and a staged firewall policy to one or more parameters for a received packet; generating, by the traffic management computing device, a policy log for the staged firewall policy and another policy log for the enforced firewall policy based on a match of one or more of the parameters of the packet to one or more access list rules of the staged firewall policy and another one or more access list rules of the enforced firewall policy, respectively; executing, by the traffic management computing device, the enforced firewall policy on the packet; determining, by the traffic management computing device, when the staged firewall policy is valid based on a comparison of the policy log for the staged firewall policy to the another policy log for the enforced firewall policy; and replacing, by the traffic management computing device, the enforced firewall policy with the staged firewall policy, when the determining indicates that the staged firewall policy is valid.
