February, foreign hacker organizations launched a high-volume DDoS attack on XBOX, one of the world's largest online gaming platforms, which had a business impact for up to 24 hours. In early March, domestic game manufacturers were also under heavy DDoS attacks. It seems that 2016 is destined to be an extraordinar
In the article prolexic released the first quarter of 2014 Global DDoS attack report published by quickshield, we learned that the attack traffic initiated by the "Reflection amplification" technology increased by 39% compared with the previous quarter, at the same time, attackers are constantly exploring other basic Internet services to launch
Counterfeit Google crawlers have become the third-largest DDoS attack tool
In the article Prolexic released the first quarter of 2014 Global DDoS attack report published by quickshield, we learned that the attack traffic initiated
identification technology to identify various DDoS attacks and hacking behavior, firewalls using Mircrokernel micro-core and activedefeense Active Defense engine technology, work at the lowest level of the system, give full play to the CPU's performance, Get amazing processing performance with just a little memory. The high-strength attack test shows that: in anti-DDoS
Riverhead, which made a very important innovation in dealing with DDoS, and presented the concept of "guidance" and the two key defenses against DDoS attacks: anti-deception defense lines and statistical analysis lines.
The system is composed of intelligent DDoS protection system detector detector and protective device guard. In foreign telecom operators, porta

To address these needs, Cisco Systems recommend DDoS defense based on guard and detector as the world's largest and strongest company in network security, as shown in Figure 2.

ObjectiveDDoS (aka "distributed denial of service") attacks have a long history, but are widely used by hackers. We can define a typical DDoS attack: An attacker directs a large number of hosts to send data to the server until it exceeds the processing power to handle legitimate requests from the normal user, eventually causing the user to fail to access the Web site normally.In recent years,
programmer's fault, but the system itself is more of an error when it is implemented. Today, buffer overflow errors are constantly being found in Unix, Windows, routers, gateways, and other network devices, and constitute the largest and most significant number of security threats to the system.
Recently, a design flaw known as buffer overflow (buffer overflow) is seriously endangering the security of the system and becoming a more headache problem

System effect this DDOS Application Layer defense system has been deployed on the http://www.yfdc.org site (if access fails, please directly access the server in China http: // 121.42.45.55 for online testing ). The defense system is at the application layer, which effectively prevents the abuse of server resources
