whitepaper The webcast outlines how Symantec Endpoint Protection for Windows XP Embedded provides a multilayered security approach that includes an application-centric firewall, application control, intrusion prevention and detection, antivirus and policy...
[17 May 2008]
whitepaper Based on this framework, a set of tools are designed that inspect and analyze both multidimensional firewall rules and traffic logs and construct the optimal equivalent firewall rules based on the observed traffic characteristics.
[15 May 2008]
whitepaper This paper presents a set of algorithms to manage rules that never apply or are redundant in a firewall configuration. Then, a subsequent rewriting of rules will derive from an initial firewall setup to an equivalent one completely free of errors.
[15 May 2008]
whitepaper Furthermore, it serves the purpose of a router firewall by identifying resource-based attacks against routers. This paper presents the novel idea of route normalization by correcting on the fly routing traffic on behalf of a local router to protect...

whitepaper This paper analyzes key Skype functions such as login, NAT and firewall traversal, call establishment, media transfer, codecs, and conferencing under three different network setups. Analysis is performed by careful study of Skype network traffic.
[14 May 2008]
whitepaper While ample research has led to tools for policy specification, correctness analysis, and optimization, few researchers have paid attention to firewall policy deployment: the process where a management tool edits a firewall's configuration to make...
[11 May 2008]
whitepaper This paper propose a novel firewall testing technique using policy-based segmentation of the traffic address space, which can intelligently adapt the test traffic generation to target potential erroneous regions in the firewall input space.
[11 May 2008]
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...

whitepaper Given this demanding environment, new methods are needed to increase network firewall performance. These critical devices filter traffic by comparing arriving packets to a list of rules, or security policy, in a sequential manner.

[11 May 2008]
whitepaper The optimization of firewall policies is critically important to provide high performance packet filtering particularly for high speed network security. Current packet filtering techniques exploit the characteristics of the filtering policies, but...
[11 May 2008]
whitepaper It also presents a new packet filtering optimization technique that uses adaptive statistical search trees to utilize important traffic characteristics and minimize the average packet matching time. However, most of the related works use...
[11 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...
[06 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 An error in a firewall policy 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...
[04 May 2008]
whitepaper Firewall technology can be used to filter this traffic. This paper provides a resource for understanding firewall design principles used in network security. Whenever domains intersect, there is a potential need for security to control traffic...

whitepaper Further more, it serves the purpose of a router firewall by identifying resource based attacks against routers. This paper presents the novel idea of route normalization by correcting on the fly routing traffic on behalf of a local router to...
[03 May 2008]
whitepaper One of the most serious threats to internal corporate servers is not from external attacks that originate outside the firewall, but from internal clients within a networked environment. This webcast describes how deploying an application layer...
[01 May 2008]
whitepaper The ISP can then send all traffic straight to the firewall to filter based on the network administrator's rules. In order to give the network more control of filtering, the firewall can be connected directly to the ISP via an Ethernet connection.
