Using Operating System Wrappers to Increase the Resiliency to Commercial Firewalls
Operating system wrappers technology provides a means for providing fine grained controls on the operation of applications software. Application proxy firewalls can gain from this technology by wrapping the proxies, thus preventing bugs (or malicious software) in the proxy from subverting the intent of the firewall. This paper describes several experiments we performed with wrappers and firewal...

متن کاملComplete Redundancy Detection in Firewalls

The function of a firewall is to examine each incoming and outgoing packet and decide whether to accept or to discard the packet. This decision is made according to a sequence of rules, where some rules may be redundant. Redundant rules significantly degrade the performance of firewalls. Previous work detects only two spec...
