whitepaper Blue Lane corrects the traffic directed at a known vulnerability, providing the benefits of patching immediately after a vendor patch is released and without the need to hastily test or install server software patches.
[17 May 2008]
whitepaper To police network traffic, firewalls must be configured with a set of filtering rules. The existence of errors in this set is very likely to degrade the network security policy. The management of these configuration errors is a serious and complex...

whitepaper Security concerns about HTTP/S traffic are greater in the corporate data center than on the open Web. Dedicated secure sockets layer and other security devices are often needed in this part of the network.
[15 May 2008]
whitepaper This paper describes a traffic-aware optimization framework to improve the operational cost of firewalls. Based on this framework, a set of tools are designed that inspect and analyze both multidimensional firewall rules and traffic logs and...

whitepaper The network incorporates wireless technology with enhanced security and ATM technology that allows greater bandwidth, to help Pennsylvania Turnpike better manage and monitor roadways and more efficiently move traffic along the toll road.
[15 May 2008]
whitepaper These critical devices filter traffic by comparing arriving packets to a list of rules, or security policy, in a sequential manner. Unfortunately packet filtering in this fashion can result in significant traffic delays, which is problematic for...

whitepaper Generating random traffic to test the functionality of firewall matching is inefficient and inaccurate as it requires an exponential number of test cases for a reasonable coverage. This paper presents a framework for automatic testing of the...
[11 May 2008]
whitepaper Current packet filtering techniques exploit the characteristics of the filtering policies, but they do not consider the traffic behavior in optimizing their search data structures. The optimization of firewall policies is critically important to...
[11 May 2008]
whitepaper These firewall rules are mostly custom-designed and hand-written thus in constant need for tuning and validation, due to the dynamic nature of the traffic characteristics, ever-changing network environment and its market demands.
[06 May 2008]
whitepaper A firewall policy error either creates security holes that will allow malicious traffic to sneak into a private network or blocks legitimate traffic and disrupts normal business processes, which in turn could lead to irreparable, if not tragic...

[04 May 2008]
whitepaper Whenever domains intersect, there is a potential need for security to control traffic allowed into the network. Firewall technology can be used to filter this traffic. A network security domain is a contiguous region of a network that operates...

whitepaper This webcast describes how deploying an application layer filtering solution such as Microsoft Internet Security and Acceleration (ISA) Server 2004 can help to minimize these threats by filtering the remote procedure call (RPC) traffic between...
[01 May 2008]
whitepaper Firewalls protect a trusted network from an untrusted network by filtering traffic according to a specified security policy. Firewall vulnerability is defined as an error made during firewall design, implementation, or configuration that can be...
[24 Apr 2008]
whitepaper The ISP can then send all traffic straight to the firewall to filter based on the network administrator's rules. If an overwhelming amount of traffic is coming into the ISP and being dropped, then only the ISP can effectively filter out the attack...
[24 Apr 2008]
whitepaper Downstream wanted to build a digital media network that can support bandwidth-intensive network traffic, and carry hundreds of video channels to remote client sites. It also wanted to ensure that network connections are secure, resilient, and...
[18 Apr 2008]
whitepaper Microsoft ISA Server works to keep inappropriate traffic and users out of the network and confidential data, but how are people making sure that the traffic that gets through is free from malicious code and inappropriate material?
[12 Apr 2008]
whitepaper This proposes FLIP, a high-level firewall configuration policy language for traffic access control, to enforce security and ensure seamless configuration management. Multiple firewalls typically cooperate to provide security properties for a...
