New technology media Tiger sniffing network attacks the incident, causing concern in the industry. February 27 Night, the Tiger Sniff network interrupted visit, the tiger sniff net Sina official Weibo immediately issued a statement, said that the site was maliciously attacked, then the tiger sniffing network in the cloud server provider Aliyun with the assistance of resuming normal access.

According to the Tiger Sniff net notice, 27th 18 o'clock in the evening Tiger Olfactory network was attacked, the attackers use ACK Flood, ICMP Flood, UDP Flood, CC Four kinds of attack forms, the constant transformation of the combination mode for savage attacks, consumption of server bandwidth resources and processing capacity, resulting in 18:04 website interruption. 18:05, Aliyun's cloud shield security system triggered, for attack characteristics, through data cleaning to intercept malicious access data, the traffic to reduce the traffic to the 1-3%, restore normal access to the site. After one hours, the attacker changed the mode of attack, attacking traffic exceeding the free cleaning limit of the cloud Shield security system, once reached 40 times times the total bandwidth of the Tiger olfactory network, Ali Cloud team began to intervene to help the Tiger olfactory network to increase bandwidth, increase the number of data passing; After the attackers changed the way again, the Tiger sniffing network uses a load balancing of cloud servers, Help the site to improve its affordability, the attack again failed. The tiger-sniffing network remained in normal access, and the attack ended after two days.

Internet illegal attack has been the malicious power of the Internet, in the traditional Internet architecture, the defense method is limited, the attack is easy to work, and cloud computing can increase the load capacity of the server to resist attack. In this attack, both sides changed the attack and defense methods, dynamic adjustment of bandwidth and load balance are the characteristics of cloud computing. It plays an important role in the process of resisting attack of Tiger olfactory network.

Tiger Sniff Network Bulletin said that the cloud computing era of attack and protection of the traditional server hosting era is in sharp contrast. Under the traditional hosting mode, a small number of attacks need to enhance their ability to attack, the larger the case, can only contact the computer room, to increase the hardware configuration-oriented way to enhance the ability to attack; The attack was more violent, but the white flag surrendered, and the reaction slowed. And in the era of cloud computing, small attacks are automatically filtered, cloud computing service providers can through flexible expansion capabilities, provide seamless performance to enhance the protection against attacks, the system to withstand a significant increase in response speed, resource matching faster and more flexible, which makes the network attack in the future may not be able to form a malicious force.

At the same time, the industry's focus on cloud computing is more focused on technology and price, while cloud computing services have always been overlooked. In the attack of Tiger olfactory net, Aliyun's quick feedback and intervention became the important reason to guarantee the normal visit of Tiger Olfactory network. It can be seen that, beyond technology, the service capabilities of cloud providers are increasingly becoming an important factor affecting user choice.
