Firewall Queries
Firewalls are crucial elements in network security, and have been widely deployed in most businesses and institutions for securing private networks. The function of a firewall is to examine each incoming and outgoing packet and decide whether to accept or to discard the packet based on a sequence of rules. Because a firewall may have a large number of rules and the rules often conflict, underst...
متن کاملDistributed Firewall Policy Validation
With hacking attempts, the cost of security breaches, and the importance of defensive computer security in general all on the rise, strong firewalls are more relevant than ever. At the same time, demands for software diversity and increasingly complex network layouts make evaluating adherence to a unified security policy especially difficult. In this paper, I propose a method of uniformly valid...
متن کاملNetwork Firewall Policy Tries ∗
Network firewalls remain the forefront defense for most computer systems. These critical devices filter traffic by comparing arriving packets to a list of rules, or security policy, in a sequential manner. Unfortunately packet filtering in this fashion can result in significant traffic delays, which is problematic for applications that require strict Quality of Service (QoS) guarantees. Further...
متن کاملArguing About Firewall Policy
In this paper, we present a new framework to analyze firewall policy by using argumentation. At the core of this new idea is extending firewall rules with the concept of “reasons” and arguing about the reasons, not the rules. Depending on how the reasons are designed, the resulting framework can be useful in a number of ways: new anomalies in a firewall policy can be identified while, at the sa...
متن کاملFirewall policy verification and troubleshooting
Firewalls are important elements of enterprise security and have been the most widely adopted technology for protecting private networks. The quality of protection provided by a firewall mainly depends on the quality of its policy (i.e., configuration). However, due to the lack of tools for verifying and troubleshooting firewall policies, most firewalls on the Internet have policy errors. A fir...
