Service-based defense policy IT Soft Services 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 IT Soft Services 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, IT Soft Services 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. IT Soft Services 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 IT Soft Services r 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, IT Soft Services 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, IT Soft Services 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 of IT Soft anti-DDoS solution:
Efficient and speedy: 200 Gbit/s defense performance and response within seconds High-performance and multi-core CPU, providing anti-DDoS products covering 2 Gbit/s to 200 Gbit/s performance to defend against all types of DDoS attack.
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 system, Can defend against hundreds of attacks 
"V-ISA" reputation technical system, Can defend against hundreds of DDoS attacks, with the industry-leading defense types.
