Background

With the IT and network evolution, the Distributed Denial of Service (DDoS) attack has already broken away from original hacker behaviors. Instead, it forms an integral dark industry chain with overwhelming damages.

Severe DDoS attacks

At present, a single DDoS attack consumes more than 100 Gbit/s bandwidth. The number of DDoS attacks is 20 times of that in 2007, and over 30,000,000 zombie hosts flood the network. Moreover, attack tools become easily available. Large numbers of botnets break off the technical threshold for DDoS attacks. A DDoS attack is launched by only three steps, namely, downloading the attack tool, purchasing zombie hosts, and initiating the attack.

Traffic DDoS attacks evolve to application attacks

In the past, flood attacks were prevailing on the carrier network and infrastructure. In comparison, current DDoS attacks are specific to applications and services, such as enterprise portal applications, e-shopping, online videos, online games, DNS, and email. The targets of attacks become more extensive. A single attack consumes less traffic and fewer costs. The attack behavior becomes more complex and difficult to distinguish. This brings difficulty in detecting and defending against DDoS attacks.

Service interruption adversely affects enterprise operation

DDoS attacks frequently intrude into the service systems of enterprises, and severely interrupt the normal service operation. On the one hand, service interruption damages enterprises' brand images, takes away their customers, and reduces their profits, especially for small Internet enterprises on e-business, online games, and portals. On the other hand, constructing an anti-DDoS system brings intensive investment and maintenance pressure on these enterprises and deteriorates their normal service operation.

DDoS attacks cause IDC customer loss

If a service system suffers from DDoS attacks, the attack traffic occupies the entire IDC bandwidth, affecting the service systems of other leasers. As a result, IDC leasers quit, competitiveness lowers, and operation costs rise. These side impacts severely deteriorate the service operation and profits.

Solution Overview

Designed for carriers, enterprises, data centers, and ICP service providers (including providers for Web portals, online games, online videos, and DNS services), Huawei anti-DDoS solution incorporates extensive experience in network security and full understanding of customer demands.

Huawei anti-DDoS solution enhances defense against application-layer attacks, IPv4-IPv6 attack defense, and defense against zombies, Trojan horses, and worms. This fully ensures network security and service continuity.

Product Features

Service-based defense policy

Huawei anti-DDoS solution supports continuously periodic learning and analysis on the service traffic of the Zone, draws the outline of normal service traffic, and enables differentiated defense types and policies for various services or one service in different time ranges, therefore implementing refined defense.

Accurate abnormal traffic cleaning

Huawei anti-DDoS solution uses the per-packet detect technology. Defense is triggered immediately by an attack. This solution applies multiple technologies, including seven-layer filtering, behavior analysis, and session monitoring, to accurately defend against various flood attacks, Web application attacks, DNS attacks, SSL DoS/DDoS attacks, and protocol stack vulnerability attacks. In this way, application servers are protected.

Intelligently caching DNS traffic

Besides accurately defending against various attacks on the DNS server, Huawei anti-DDoS solution supports DNS cache for improved performance under heavy DNS server traffic.

Defense against prevailing zombies/Trojan horses/worms

By spreading Trojan horses and worms to large numbers of hosts, hackers control the hosts hierarchically and form the botnet to launch attacks. Therefore, botnets breed DDoS attacks. Huawei anti-DDoS solution identifies and blocks over 200 common zombies/Trojan horses/worms worldwide, therefore smashing botnets

Perfect IPv4-IPv6 defense

In February 2011, IANA declared that IPv4 addresses were exhausted. Enterprises have no new IPv4 addresses and begin to put IPv6 network construction into agenda. The particular IPv4-IPv6 technology of Huawei anti-DDoS solution supports concurrent defense against DDoS attacks on both IPv4 and IPv6 networks. The solution addresses the DDoS attack defense requirements in dual stack and helps users transit to the next generation network.

Flexible networking

The anti-DDoS solution must be adaptive to various network environments and address different grades of service requirements.

On this basis, Huawei anti-DDoS solution provides multiple in-line and off-line deployments, which enable customers to select flexibly by their services and networks.

In-line deployment: serially connects the detecting and cleaning modules to the network to be protected for direct traffic detecting and cleaning. The high-performance and multi-core hardware platform in use not only ensures the detecting and cleaning accuracy, but also minimizes the processing delay. Moreover, Huawei anti-DDoS solution provides the bypass module. When an anomaly occurs, traffic is sent to the cleaning module, which avoids introducing new failures.

Off-line traffic-diversion deployment: deploys the cleaning module on the network in off-line mode. Once detecting DDoS attack traffic, the detecting and cleaning centers perform actions based on the policies configured in the management center.

Highlights

Efficient and speedy: 5 Gbit/s defense performance and response within seconds

High-performance multi-core CPU as well as dedicated anti-DDoS operating system, providing 5 Gbit/s performance.

Self-learning of the service model and per-packet detect technology. Once a traffic or packet anomaly is found, the defense policy is automatically triggered.

The defense latency is within two seconds.

Accurate and comprehensive: “V-ISA” reputation technical to defend against hundreds of attacks

Particulaer “V-ISA” reputation technical to defend against over 100 DDoS attacks, with the industry-leading defense types.

Defense against over 200 zombies, Trojan horses, and worms, protecting users from hackers.
