چکیده
This paper commences by explaining some firewall definitions in order to understand basic terms for firewall techniques. Three firewall techniques, from packet filtering through to proxy services and stateful packet inspection are then discussed. Following techniques, various firewall architectures, ranging from dual-home host architecture, screened host architecture and screened subnet architecture are also covered. Finally, firewall business aspects and technological choices for hardware and software platforms are addressed.

As it is infeasible to examine and test each firewall for all possible potential problems, a taxonomy is needed to understand firewall vulnerabilities in the context of firewall operations. This paper describes a novel metho...

Firewall is a typical security system that extensively secures the private networks. The operation of a firewall is to analyze every packet and decide whether to accept or discard it based upon the firewall policy. This policy is specified as a set of rules. The work focuses on inter-firewall optimization over distinct administrative domain without exploiting the privacy policies. With the mass...
متن کاملA Firewall Network System for Worm Defense in Enterprise Networks
From a security point of view, the Internet is too open. The central idea of a traditional “firewall” is to constrain service requests from the Internet to a local network. As an enterprise network becomes larger and more flexible, an Internet worm can easily find a way to enter it. Based on the “defense-in-depth” principle, we present a “Firewall Network System” for worm defense in an enterpri...

متن کاملAn Extensible, System-On-Programmable-Chip, Content-Aware Internet Firewall
An extensible firewall has been implemented that performs packet filtering, content scanning, and per-flow queuing of Internet packets at Gigabit/second rates. The firewall uses layered protocol wrappers to parse the content of Internet data. Packet payloads are scanned for keywords using parallel regular expression matching circuits. Packet headers are compared to rules specified in Ternary Co...
