IDS are becoming the logical next step for many organizations after deploying firewall technology at the network perimeter. IDS can offer protection from external users and internal attackers, where traffic doesn't go past the firewall at all. However, the following points are very important to keep in mind. 1.

Using statistical analysis strategy, a large-scale firewall log files is analyzed and two main characteristics, the protocol field and the IP address field, is extracted in this paper. Based on the extracted features and the characteristics of multi-tree and dual-index strategy, we design a better firewall optimization algorithm. Compared with the Stochastic Distribution Multibit-trie (SDMTrie)...

The LANL transparent web proxy lets authorized external users originating from the Internet to securely access internal intranet web content and applications normally blocked by a firewall. Unauthenticated access is still, of course, denied. The proxy is transparent in that no changes to browsers, user interaction, or intranet web servers are necessary. The proxy, a few thousand lines of C runn...

Firewalls are widely adopted for protecting private networks by filtering out undesired network traffic in and out of secured networks. Therefore, they play an important role in the security of communication systems. The verification of firewalls is a great challenge because of the dynamic characteristics of their operation, their configuration is highly error prone, and finally, they are consi...
