Heuristic Route Discovery for Shared Firewall Network

SPAND: Shared Passive Network Performance Discovery

In the Internet today, users and applications must often make decisions based on the performance they expect to receive from other Internet hosts. For example, users can often view many Web pages in low-bandwidth or highbandwidth versions, while other pages present users with long lists of mirror sites to chose from. Current techniques to perform these decisions are often ad hoc or poorly desig...

Network 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...

Firewall Policy Advisor for Anomaly Discovery and Rule Editing

Firewalls are core elements in network security. However, managing firewall rules, especially for enterprize networks, has become complex and error-prone. Firewall filtering rules have to be carefully written and organized in order to correctly implement the security policy. In addition, inserting or modifying a filtering rule requires thorough analysis of the relationship between this rule and...

Development of Smart Firewall Load Balancing Framework for Multiple Firewalls with an Efficient Heuristic Firewall Rule Set

Firewalls are the devices that we are used to protect data. It might be configured to allow certain devices or applications to access our network. The Firewalls are termed as stateful devices. Traditional firewalls typically need to inspect each packet to ensure that it adheres to the policy that has been configured or not, and then perform the necessary action associated to that particular rul...
