Secure Computing Case Study: Niagara Corporation
White Paper The company wanted to improve security and reduce costs by replacing outdated firewalls, improving remote access, connecting the US and UK and reducing the dependence on UK leases lines. Niagara Corporation is one of the world's foremost producers... [11 Jul 2008]
Firewalls in Linux: Principles and Implementation
White Paper It also gives a historical, architectural and technical overview of firewalls and security attacks. This paper is meant to provide techniques in building and installing a standalone packet filtering firewall in Linux machines, mainly for small... [10 Jul 2008]
Firewalls and Virtual Private Networks
White Paper In particular, it will discuss how firewalls are used to protect corporate resources from outside intruders and how virtual private networks enable branch offices and remote users to access the corporate network in a secure manner via non-secure... [10 Jul 2008]
Managing Distributed Personal Firewalls With Smart Data Servers
White Paper The classical solution to protect networks against criminal attacks with firewalls is problematic, though. On the one hand, attacks from the inside are hardly prevented by firewalls, on the other, mobile computing poses additional security risks to... [10 Jul 2008]
Streaming Video and Firewalls: Is It Safe?
White Paper Firewalls exist to prevent unwanted data from passing between any two networks. With network horror stories reaching urban legend proportions, network administrators and their firewalls are faced with the impossible task of "Proving a negative... [10 Jul 2008]
Adaptive Detection of Worms/Viruses in Firewalls
White Paper All packets pass through firewalls and only firewalls are able to prevent packets from entering the network. This paper seeks to answer the question: "How to detect worms/viruses, which are replicated via emails, at the level of a firewall without... [10 Jul 2008]
The Use and Usability of Direction-Based Filtering in Firewalls
White Paper However, most firewalls are also capable of filtering based on a packet's direction: which network interface card the packet is crossing, and whether the packet is crossing the interface from the network into the firewall (''Inbound'') or vice... [10 Jul 2008]
PIX Vs. WatchGuard Firewalls: A Comparison Document

Automatic Analysis of Firewall and Network Intrusion Detection System Configurations
White Paper Given a network that deploys multiple firewalls and Network Intrusion Detection Systems (NIDSs), ensuring that these security components are correctly configured is a challenging problem. Although models have been developed to reason independently... [10 Jul 2008]
Deep Inspection: Next Generation Firewall Technology
White Paper Stateful inspection firewalls are the most-widely used defense against hackers. Stateful inspection firewalls were never designed to protect against web application attacks. A new generation of deep inspection firewalls is emerging to address the... [10 Jul 2008]
