whitepaper UserGate Firewall & Proxy 5.02008-10-09 Entensys
  UserGate Firewall & Proxy 5.0 is a secure server with anti-virus & anti-spam, built-in firewall with NAT and web content filtering proxy for controlled Internet sharing. Access Internet from LAN using the included categorized web filter system and the built-in firewall provides effective protection against unauthorized access. Shared Internet access through the proxy server provides network users with a secure connection to the Internet. Through a simple web interface it is possible to manage users, rights, Internet access and control server access. As the Internet becomes more widespread, organizations will become more reliant on the Internet and the services it provides. With UserGate server any organization can harness the power of the Internet, and take advantage of services like attack & virus protection and shared Internet access.

whitepaper Protecting SIP Proxy Servers From Ringing-Based Denial-of-Service Attacks2008-09-17 University of Illinois
  As Internet telephony systems continue to replace existing Public Switched Telephone Network systems, proxy servers running the Session Initiation Protocol (SIP) will continue to grow in importance for Voiceover-IP deployments that use SIP for call signaling. Since the protection of the global telecommunications infrastructure is critical to people's everyday lives, ensuring the availability of SIP proxy servers under attack should be a high priority. This paper first describes a disruptive denial-of-service attack that exploits the semantics of the SIP protocol to exhaust resources at a stateful SIP proxy server. Unlike previous approaches that focus on flooding-based denial-of-service attacks, the paper considers attacks that do not result in high incoming call traffic rates at the SIP proxy server.

whitepaper What Is a Proxy Server?2008-09-13 SecPoint
  A proxy server, also known as a "Proxy" or "Application level gateway", is a computer that acts as a gateway between a local network (e.g., all the computers at one company or in one building) and a larger-scale network such as the Internet. Proxy servers provide increased performance and security. In some cases, they monitor employees' use of outside resources. A proxy server works by intercepting connections between sender and receiver. All incoming data enters through one port and is forwarded to the rest of the network via another port. By blocking direct access between two networks, proxy servers make it much more difficult for hackers to get internal addresses and details of a private network.

whitepaper Anonymous Proxy: A Growing Trend in Internet Abuse2008-09-09 Bloxx
  Anonymous proxies are an unseen threat--a student's or employee's backdoor to malicious or productivity-sapping sites on the Internet. If your URL filtering solution relies on the old-school URL database/keyword approach, your ship is leaking and you may not see the holes.

With hundreds of new proxy sites created each day, traditional URL filtering just can't keep up, even when supplemented by standard keyword analysis. This paper offers a primer on the problems, the sizable costs and time drain for IT professionals, and a discussion of an effective third-generation solution that goes far beyond the traditional strategy.

whitepaper Connection Caching for WWW Servers and Proxies2008-06-10 University of Electro-Communications
  This paper proposes connection caching to reduce the overhead of accessing WWW pages. Connection caching means that a WWW server or a WWW proxy server does not release its connection with a client or a peer but retains it and uses it again after the transmission is completed. The retained connection is cached and it is used for future access. Connection caching reduces network traffic and server load. This paper shows that the hit rate of connection caching for WWW accesses is high and connection caching is effective. This evaluation is based on actual logs from a server and a proxy server. The logs are records of 350 days. The log from the proxy server includes more than 14 million accesses.

whitepaper Back-to-Back User Agent (B2BUA) SIP Servers Powering Next Generation Networks2008-02-27 RADVision
  SIP Back-to-Back User Agent (B2BUA) Servers are probably one of the most important and powerful types of SIP Servers. B2BUA servers are commonly used to develop and offer value added features. The difference between Proxy server and B2BUA server is sometimes not fully understood, but effectively B2BUA servers are much stronger and intelligent entities that can perform actions which Proxy servers cant. This white paper provides managers in the VoIP and real-time multimedia industry an overall understanding of B2BUA servers. Better understanding of B2BUA servers can help managers understand the value, and the tradeoffs, of choosing a B2BUA server as the framework for developing a wide range of SIP applications and SIP services.

whitepaper Next Generation Proxy Servers2008-02-20 University of Colombo School of Computing
  Proxy Servers currently play an important role in a network by making efficient use of bandwidth through caching. This paper discusses on broadening the concept of proxy and Internet cache to suit current and future web 2.0 and web X.0 trends, especially in the areas of audio, video, blogging, social networking and mesh computing technologies. In doing so, the paper presents ideas of a Next Generation Caching Server implemented as a platform for developing web service oriented applications and share the knowledge and experience gained in deploying a prototype at the University Network one works in.

whitepaper Automatic Remediation for SOA Web Services: ORION SOAP Proxy Based on ORION SOA 7.012008-01-28 EventGnosis
  Web services are becoming an integral part of the business infrastructure, and the availability and proper functioning of individual web services is mission critical. The only way to assure 99.999% services availability and to maintain the required transaction performance and throughput is to be able to monitor individual SOAP transactions as are they are being processed. Performance and availability problems have to be identified in real-time and may require automatic remedial actions on a wide range of infrastructure components on the network, such as application servers, databases, and web servers. The ORION SOA 7.0 rule-based application server can be deployed as an in-line SOAP Proxy or as an out-of-band transaction monitor to identify and remediate problems.

whitepaper On the Scalability of an Image Transcoding Proxy Server2008-01-01 Polytechnic University
  Image transcoding proxies are used to improve Web browsing over low bandwidth networks by adapting content-rich web images to bandwidth-constrained clients. Such transcoding proxies dynamically analyze, manipulate and transcode images (e.g. quality reduction, down sampling) on the fly enabling significant reductions in download times over low bandwidth links. However, transcoding proxies have scalability problems if the objective policy that decides whether to transcode an image does not take the client load (e.g. number of concurrent clients) into consideration. The paper shows that seemingly intuitive policies that make decisions solely based on whether transcoding yields savings in transmission time fail to scale.
