Structured firewall design
A firewall is a security guard placed at the point of entry between a private network and the outside Internet such that all incoming and outgoing packets have to pass through it. The function of a firewall is to examine every incoming or outgoing packet and decide whether to accept or discard it. This function is conventionally specified by a sequence of rules, where rules often conflict. To r...

متن کاملAddressing Next-Gen Firewall Design Challenges Part II: Stateful Firewall Concepts And Design Issues
The hashing function is used to map a large address space to a much smaller space. If that space is for IPv4 IP addresses, for example, the total space is 2564. Storing the IP address information in an array would yield search results in one memory access but would require over 4 Gbit of memory. For most applications only a small subset of the total space is dealt with resulting in the majority...
متن کاملProactive Security Mechanism and Design for Firewall
In this paper we have present the architecture and module for internet firewall. The central component is fuzzy controller while properties of packets are fuzzified as inputs. On the basis of proposed fuzzy security algorithm, we have figured out security level of each packet and adjust according to packets dynamic states. Internet firewall can respond to these dynamics and take respective acti...
متن کاملFirewall Design: Understandable, Designable and Testable
Firewalls are the cornerstones of network security. To make firewalls working effectively, firewall manager must design firewall rules and the rule order correctly. In this paper, we present a firewall management toolkit which makes firewall rules understandable, designable and testable. Understandable means that the rules shown to the manager are easily understood. Designable means that it is ...
