The possibility of DDoS attacks to your enterprise depends on your enterprise's operating method, attacker's whimsy, or enterprise's competitors.

Interruption of services (denial of service) Before discussing DDoS we need to know about DOS, DOS refers to hackers trying to prevent normal users to use the services on the network, such as cutting the building's telephone lines caused users can not talk. and to the network, because of bandwidth, network equipment and server host processing capacity has its limitations, so when the hacker generated excessive network packet so that the device can no

With the development of computer network technology, Wireless LAN has become a high-speed development of wireless communication technology in the computer network to achieve communication mobility, personalization and multimedia applications. However, because the transmission media of wireless communication is the air with no entity protection, the data sent by wireless can reach all the terminals within the coverage range, or it is an unexpected receiving device, which provides more and more co

DDoS (Distributed denial of service) attack is a simple and fatal network attack using TCP/IP protocol vulnerability, because the TCP/IP protocol is unable to modify the session mechanism, so it lacks a direct and effective defense method. A large number of examples prove that the use of traditional equipment passive defense is basically futile, and the existing firewall equipment will be paralyzed due to limited processing capacity, become a network

At present, such a huge peak of 0.95 million QPS of HTTPS/ssl cc attacks, has far surpassed the performance bottleneck of most domestic protection vendors.In the end, the Alibaba Cloud security anti-DDoS system successfully defended against hacker attacks, stored a large amount of effective attack evidence,
