Due to the lack of a standardized methodology for reporting firewall performance, current datasheets are designed for marketing and provide inflated throughput measurements obtained under unrealistic scenarios. As a result, customers lack usable metrics to select a device that best meets their needs. In this paper, we develop a systematic approach to estimate the performance offered by stateful...

The aim of the research is to investigate techniques that support the development of highly dependable applications in a distributed system environment. Techniques we developed include redundant task allocation, load balancing, fault-tolerant computing and communication. The application we have implemented in the system is a firewall application. The firewall runs in redundant mode. Each incomi...

Firewalls have an important role in network security. However, managing firewall policies is an extremely complex task because the large number of interacting rules in single or distributed firewalls significantly increases the possibility of policy misconfiguration and network vulnerabilities. Moreover, due to low-level representation of firewall rules, the semantic of firewall policies become...

An XML firewall differs from a conventional firewall because its major task is to control access to web services rather than to filter untrusted addresses. An XML firewall can effectively protect web services from being attacked by inspecting a complete XML message including its head and data segments, and rejecting unauthorized web services invocation. In this paper, we propose a formal XML fi...

Firewalls are the core elements in network security & access control. A firewall controls the flow of traffic between different areas of your network. It uses a rule set called as firewall policy for this purpose. However as the size of rule set increases, specification and verification of the firewall rules becomes complicated and error-prone. This paper serves to provide an overview of the re...

We show firewall causing directional spike propagation in a recurrent network. The firewall is inhibition that dynamically and ubiquitously emerges in a recurrent network and is selectively activated by spike propagation in a particular direction. Therefore, the dynamical firewall can control spike propagation emerging from any site in a network. Keywords— Dynamical Firewall, Directional Spike ...

    The article attempts to have neural network and genetic algorithm techniques present a model for classification on dataset. The goal is design model can the subject acted a firewall in network and this model with compound optimized algorithms create reliability and accuracy and reduce error rate couse of this is article use feedback neural network and compared to previous methods increase a...

In this project we conducted a user study of Microsoft Windows Vista Firewall: a lab study followed by a questionnaire to evaluate the usability of Vista’s personal firewall. Our results show that the main problem with Windows Vista Firewall is that many users are unable to open the Advanced Management Interface of Windows Vista Firewall. Our overall impression was that users were relatively un...

Traditional network firewalls prevent unauthorised access and attacks by protecting the points of entry into the network. Currently, however, there is no standard mechanism by which a firewall identifies and controls the flow of Internet Inter-ORB Protocol (IIOP), that has become the de-facto standard interoperability protocol for Internet providing "out-of-the-box" interoperation with ORBs, an...
