On the Safety and Efficiency of Firewall Policy Deployment

whitepaper It show that naive deployment approaches can easily create a temporary security hole by permitting illegal traffic, or interrupt service by rejecting legal traffic during the deployment. Firewall policy management is challenging and error-prone.

Policy Segmentation for Intelligent Firewall Testing

whitepaper This paper propose a novel firewall testing technique using policy-based segmentation of the traffic address space, which can intelligently adapt the test traffic generation to target potential erroneous regions in the firewall input space.

Detection and Removal of Firewall Misconfiguration

whitepaper To police network traffic, firewalls must be configured with a set of filtering rules. The existence of errors in this set is very likely to degrade the network security policy. The management of these configuration errors is a serious and complex...
