It examines the network packets and decides whether to accept or deny them. But when a packet matches two or more filters conflicts arise. Due to the conflicts,�...

To solve this problem, we propose a topological approach called BISCAL (Bit-vector based spatial calculus) to detect the conflicts in the firewall policies. As�...

Abstract—Packet filtering provides initial layer of security based upon set of ordered filters called firewall policies. It examines the network packets and�...

TL;DR: A topological approach called BISCAL (Bit-vector based spatial calculus) to detect the conflicts in the firewall policies is proposed, which can reduce�...

Discover how firewalls use packet filtering to protect networks from unauthorized access. Learn about the challenges of maintaining firewall policies and�...

Conflict is a misconfiguration that occurs when a packet matches two or more filters. The occurrence of conflicts in a firewall policy makes the filters either�...
