چکیده

The distributed firewall is an important new line of network defense. It provides fine-grained access control to augment the protections afforded by the traditional perimeter firewall. To be effective, though, a distributed firewall must satisfy two critical requirements. First, it must embrace a protection model that acknowledges that everything behind the firewall may not be trustworthy. The malicious insider with unobstructed access the network can still mount limited attacks. Second, the firewall must be tamperresistant. Any firewall that executes on the same untrusted operating system that it is charged to protect begs the question: who is protecting whom? This paper presents a new distributed, embedded firewall that satisfies both requirements. The firewall filters Internet Protocol traffic to and from the host. The firewall is tamper-resistant because it is independent of the host’s operating system. It is implemented on the host’s network interface card and managed by a protected, central policy server located elsewhere on the network. This paper describes the firewall’s architecture and associated assurance claims and discusses unique applications for it.

Evaluation of Three Approaches for CORBA Firewall/NAT Traversal

Applications that use CORBA as communication layer often have some restrictions for multi-domain deployment. This is particularly true when they have to face firewall/NAT traversal. Furthermore, nowadays there isn’t a well-accepted unique or standardized solution adopted by all ORBs, compelling applications using this middleware to use proprietary solutions that sometimes do not address the env...

Agent Systems in Software Engineering

During the last decade the continuous growth of the Web resulted in a significant development shift from simple types of software applications to distributed multi-tier web-based applications. In general, distributed systems are by nature more complex than centralized systems. As a result, the software engineering tasks of these systems are also complicated. Unlike traditional software applicat...
