Any delays or interruptions in connectivity can easily result in reduced productivity, lost business opportunities and a damaged reputation. Maintaining a reliable and efficient internet connection to ensure the operation of critical applications is therefore key to the success of the enterprise. FortiWAN intelligently balances internet and intranet traffic across multiple WAN connections, providing additional low-cost incoming and outgoing bandwidth for the enterprise and substantially increased connection reliability. FortiWAN is supported by a user-friendly UI and a flexible policy-based performance management system. FortiWAN provides a unique solution that offers comprehensive multi-WAN management that keeps costs down as well as keeping customers and users connected. Product Benefits FortiWAN is the most robust, cost-effective way to: l Increase the performance of your: l Internet access l Public-to-Enterprise access l Site-to-site private intranet l Lower Operating Costs l Increase your network reliability l Enable Cloud / Web 2.0 Applications l Monitor Network Performance Increase Network Performance FortiWAN increases network performance in three key areas: l Access to Internet resources from the Enterprise l Access to Enterprise resources from the Internet l Creation of Enterprise Intranet connections between sites FortiWAN intelligently aggregates multiple broadband and/or leased access lines to significantly increase Internet access performance. FortiWAN makes reacting to network demands fast, flexible and inexpensive. FortiWAN transforms underperforming networks into responsive, cost-effective and easy-to-manage business assets. FortiWAN load balances Internet service requests from Enterprise users, optimally distributing traffic across all available access links. FortiWAN’s 7 different Load Balancing algorithms provide the flexibility to maximize productivity from any network scenario. FortiWAN gives you high-performance inter-site connectivity without the need to lease expensive links such as T1 and T3. FortiWAN aggregates multiple low-cost Internet access links to create site-to-site Virtual Private Line 8 FortiWAN Handbook Fortinet Technologies Inc. Product Benefits Introduction (VPL) Tunnels for LAN-like performance between company locations. By using multiple carriers and media, reliability of these VPL Tunnels can exceed that of traditional engineered carrier links. Substantially Lower Operating Costs Once bandwidth requirements exceed traditional asymmetrical Internet access services (like ADSL) there is a very high jump in bandwidth cost to engineered, dedicated access facilities like DS-1/DS-3. Even Metro Ethernet is a large cost increment where it is available. Adding shared Internet access links is substantially less expensive and delivery is substantially faster. Traditional point-to-point private lines for company intranets are still priced by distance and capacity. Replacing or augmenting dedicated point-to-point services with Virtual Private Line Tunnels reduces costs substantially while increasing available bandwidth and reliability. FortiWAN makes low-cost network access links behave and perform like specially-engineered carrier services at a fraction of the cost. l Deploy DSL services and get DS-3/STM-1-like speed and reliability while waiting for the carrier to pull fiber. l Add and remove bandwidth for seasonal requirements quickly and easily. l Increase bandwidth to web servers and use multiple ISPs without BGP4 management issues. Increase Network Reliability Businesses can no longer afford Internet downtime. FortiWAN provides fault tolerance for both inbound and outbound IP traffic to ensure a stable and dependable network. Even multiple link failures, while reducing available bandwidth, will not stop traffic. By using diverse media (fiber, copper, wireless) and multiple ISPs (Telco, Cableco, 4G), FortiWAN can deliver better than carrier-class “5-9’s” reliability. FortiWAN can be deployed in High Availability mode with fully redundant hardware for increased reliability. Larger FortiWAN models also feature redundant power supplies for further protection from hardware failures. Enable Cloud / Web 2.0 Applications Traditional WAN Optimization products expect that all users connect only to Headquarters servers and Internet gateways over dedicated, symmetric leased lines, but that is already “yesterday’s” architecture. Today users want to mix HQ connectivity with direct Cloud access to Web 2.0 applications like email, collaborative documentation, ERP, CRM and online backup. FortiWAN gives you the flexibility to customize your network, giving you complete control. Direct cloud-based applications to links optimized for them and reduce the bandwidth demand on expensive dedicated circuits. Combine access links and/or dedicated circuits into Virtual Private Line Tunnels that will support the fastest video streaming or video conferencing servers that Headquarters can offer. FortiWAN is designed for easy deployment and rapid integration into any existing network topology. Monitor Network Performance

    4620-1 ch05.f.qc 10/28/99 12:00 PM Page 157 Chapter 5 Troubleshooting TCP/IP In This Chapter ᮣ Troubleshooting TCP/IP in Windows 2000 Server ᮣ TCP/IP troubleshooting steps ᮣ Defining which is the best TCP/IP troubleshooting tool to solve your problem ᮣ Mastering basic TCP/IP utilities roubleshooting is, it seems, an exercise in matrix mathematics. That is, Twe use a variety of approaches and influences to successfully solve our problems, almost in a mental columns-and-rows format. These approaches may include structured methodologies, inductive and deductive reasoning, common sense, experience, and luck. And this is what troubleshooting is made of. Troubleshooting TCP/IP problems is really no different from troubleshooting other Windows 2000 Server problems mentioned in this book, such as instal- lation failures described in Chapter 2. Needless to say, Windows 2000 Server offers several TCP/IP-related tools and utilities to assist us, but more on the specifics in a moment. TCP/IP Troubleshooting Basics The goal in TCP/IP troubleshooting is very simple: fix the problem. Too often, it is easy to become overly concerned about why something happened instead of just fixing the problem. And by fixing the problem, I mean cost effectively. 1. Be cost effective. Don’t forget that several hours’ worth of MCSE-level consulting could more than pay for the additional bandwidth that may easily solve your TCP/IP WAN-related problem. Don’t overlook such an easy fix when struggling to make a WAN connection between sites utilizing Windows 2000 Server. Too little bandwidth is typically the result of being penny wise and pound foolish.

  • Dos Amplification Attacks – Protocol-Agnostic Detection Of
    DoS Amplification Attacks – Protocol-Agnostic Detection of Service Abuse in Amplifier Networks B Timm B¨ottger1( ), Lothar Braun1 , Oliver Gasser1, Felix von Eye2, Helmut Reiser2, and Georg Carle1 1 Technische Universit¨at M¨unchen, Munich, Germany {boettget,braun,gasser,carle}@net.in.tum.de 2 Leibniz Supercomputing Centre, Munich, Germany {voneye,reiser}@lrz.de Abstract. For many years Distributed Denial-of-Service attacks have been known to be a threat to Internet services. Recently a configura- tionflawinNTPdaemonsledtoattackswithtrafficratesofseveral hundred Gbit/s. For those attacks a third party, the amplifier, is used to significantly increase the volume of traffic reflected to the victim. Recent research revealed more UDP-based protocols that are vulnerable to amplification attacks. Detecting such attacks from an abused ampli- fier network’s point of view has only rarely been investigated. In this work we identify novel properties which characterize ampli- fication attacks and allow to identify the illegitimate use of arbitrary services. Their suitability for amplification attack detection is evaluated in large high-speed research networks. We prove that our approach is fully capa- ble of detecting attacks that were already seen in the wild as well as capable of detecting attacks we conducted ourselves exploiting newly discovered vulnerabilities. 1 Introduction Denial-of-Service attacks aim at making services unavailable to their intended users. Attackers can use different methods to consume bandwidth or deplete other resources of the victim. One method to exhaust bandwidth is called Dis- tributed Reflection Denial-of-Service (DRDoS) attack: an attacker sends forged requests to several servers with the victim’s spoofed source address.

  • Ddos Beasts and How to Fight Them
    DDoS Beasts and How to Fight Them Artyom Gavrichenkov <[email protected]> Timeline of ancient history • First attacks: 1999-2000 • 2005: STRIDE model by Microsoft • Spoofing Identity • Tampering with Data • Repudiation • Information Disclosure • Denial of Service • Elevation of Privileges [D?]DoS The difference between “a distributed attack” and an, err, not distributed one is vague. Traditional meaning: a distributed attack comes from multiple sources. • What is a source? Is it an IP address or a machine? • If it is a machine, does a virtual instance count? Or a few instances under the same physical hypervisor? What if they often migrate between physical machines? If I’m a victim, how do I tell a single-sourced from a multiple-sourced? • If it is an IP, then how do we treat spoofed traffic? [D?]DoS Hence, a different sort of thinking applies: • DoS (as implied in STRIDE): a vulnerability in a software (e.g. NULL pointer dereference, like Ping of Death) • DDoS: computational resource exhaustion Risk management The basic idea behind STRIDE and other approaches is risk assessment, modelling and management.
