Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The synflood attack in the DDOS attack is ubiquitous, and an attacker consumes all available server resources to stop the server from responding to a normal TCP connection request by repeatedly sending an initial connection request syn packet, so that the service is paralyzed or even crashed. In order to overcome the defects, the application provides a synflood attack protection scheme, real-time flow data flowing into an attack target is monitored at a network position far away from the attack target, namely close to an attack source, and a synflood attack is found in a network segment where the attack flow does not reach the attack target, so that network blockage at the attack target is avoided. On the basis, the proportion of the syn type traffic data in the real-time traffic data is compared with the proportion of the normal real-time traffic data to perform synflood attack protection, and a stable network environment is provided.
Fig. 1 is a flowchart of a synflood attack protection method according to an embodiment of the present disclosure. Referring to fig. 1, the method for protecting against synflood attack includes:
s11: acquiring all real-time traffic data at a preset network position between an attack source and an attack target; the preset network position is any position between the attack source and the attack target except for a network link of a network segment where the attack target is located.
In the embodiment, all real-time traffic data at a preset network position between an attack source and an attack target are obtained; the preset network position is any position between the attack source and the attack target except for a network link of a network segment where the attack target is located. Specifically, the preset network location is a network entry of a network segment where the attack target is located or an Internet Service Provider (ISP) network. Meanwhile, a flow monitoring device is arranged at a network entrance of the network segment where the attack target is located, and all real-time flow data at the network entrance are obtained by using the flow monitoring device.
As shown in fig. 2, four network layers are divided between the attack source and the attack target: attack source network, farther upstream ISP network, target network. The synflood attacks are distributed in a real network environment in a funnel shape, and a plurality of puppet machines (attack sources) controlled by an attacker launch attacks at many different positions, which are the upper parts of the funnels, and in contrast, the attacked traffic is finally converged at the bottom parts of the funnels, i.e. the network segments of target hosts (attack targets). The method comprises the steps of carrying out flow monitoring in a target network, if proper filtering measures are not available, the last attack message can be converged to the target network, installing corresponding flow monitoring equipment at this time, judging that a system is attacked by synflood easily and accurately, but protecting the system at the position, wherein the defects are obvious, the interception place is too late, the attack flow is converged in a network segment where the protecting equipment is located, at the moment, flow blockage is generated, protecting is carried out quickly in time, certain time is still needed for processing, the network environment of an upstream network can be disordered, and the forwarding performance of a plurality of upstream networks is wasted. Compared with the method for protecting the network in the position close to the protection equipment, although the attack flow is easier to distinguish, the attack flow already comes to the same network segment of the protection equipment, and the situation of network congestion is easy to occur, the position where the flow monitoring is best to carry out the filtration of the attack data packet or the illegal data packet is carried out in the attack source network, the filtration is carried out at the position, the attack message can be intercepted at the earliest, the influence on other networks can be reduced to the minimum, the efficiency of the whole network segment can be better improved, and because the later filtration function is realized, a large amount of useless messages for attack can be flooded in a plurality of network environments below the other networks for a longer time, and the forwarding function of the network is wasted. However, due to the fact that the attack source is unknown or distributed, it is difficult to monitor the attack in the attack source network unless a large number of puppet machines for attack are all centralized in the same network.
It is more advantageous to comprehensively consider that it is more advantageous to discover that the network attack is earlier found and intercept the attack, and the network attack launched from the attack source is concentrated more downwards and more towards the target host, and monitoring equipment is set at a position closer to the attack source end at a network position far away from the target host as far as possible, that is, equipment capable of monitoring and counting packets is connected to a router corresponding to the network position far away from the target host as far as possible, so that the attack traffic is intercepted earlier, and the situation of network congestion is avoided. Therefore, the embodiment of the application protects the entrance of the ISP network, the target ISP network or the target network farther upstream close to the attack source, and can process the attack flow when the attack flow does not reach the network segment where the protection equipment is located, so that network congestion is reduced, and the running environment of the equipment is more stable. Furthermore, the effect of setting the traffic monitoring device in the upstream ISP network or the target ISP network is more prominent, because the two networks are located closer to the attack source network, the interception time point is earlier, and the network range capable of being protected is larger, the defect is that the cost for deploying the device is correspondingly higher, but the benefit brought is also huge, and the complex attack message in the network environment can be processed earlier, so that a better protection effect is generated on the downstream network environment.
S12: determining the target ratio of syn type flow data in all real-time flow data, judging whether the target ratio exceeds a reference ratio, and if so, controlling the flow of all real-time flow data; and the reference proportion is the proportion of syn type traffic data in all historical traffic data without attack traffic at the preset network position in a historical period.
In this embodiment, a target ratio of syn-type traffic data in all real-time traffic data is determined, and it is determined whether the target ratio exceeds a reference ratio, and if so, flow control is performed on all real-time traffic data; and the reference proportion is the proportion of syn type traffic data in all historical traffic data without attack traffic at the preset network position in a historical period. On the basis of step S11, a new device capable of monitoring and counting messages is added to the router as far as possible away from the protective device, a threshold is set according to the proportion of the syn message in the total message under normal conditions, and when the traffic monitoring exceeds the threshold, the attack traffic is processed. The determining process of the target ratio may specifically be to count a target data amount of syn-type traffic data in all the real-time traffic data by using the traffic monitoring device, and then calculate a ratio of the target data amount in all the real-time traffic data to obtain the target ratio. And comparing the target occupation with the reference occupation, if the target occupation exceeds the reference occupation, indicating that synflood attack exists in the real-time traffic data, determining synflood attack traffic in all the real-time traffic data, and performing speed-limiting processing or intercepting processing on the synflood attack traffic. The flow monitoring equipment can count the number of receiving and sending packets and the number of syn packets of a second level of a network interface of a specified network card, when an attack occurs, once the proportion of a corresponding message exceeds a set threshold value under a normal condition, the attack flow is limited or intercepted immediately, and after the attack is intercepted, the attack flow can be effectively prevented from continuing to descend to cause the flow blockage of a network segment of the protective equipment.
Based on the characteristics of DDOS attack, a large amount of attacks are converged on a final target host or a target network segment, and each attack has obvious attack characteristics, such as synflood attack, the number of semi-connections caused by the attack is far more than that in the network segment in a normal state, the number of data packets with the SYN end set to be 1 in one network segment is less than 200 within 1 second under a normal condition, however, the number of the packets can be easily set to be 3000 per second by using the special attack tool and is far more than a normal level, so that the target host or the target network segment can be filled with a large amount of the attack packets in a short time, the resources of a server are quickly exhausted, and the purpose of attack is achieved. Accordingly, however, by using this feature, it is possible to easily detect that a synflood attack has occurred in a network segment, or that a zombie machine has been controlled by a real attacker and attacked to a target host or network segment unconsciously. The attack method can quickly achieve the purpose of attack by simply improving the sending of the attack data packet, but because the attack characteristic is far higher than that of the normal state, an approximate threshold value can be selected according to the characteristic to carry out corresponding protection. Therefore, it is reasonable to set the reference ratio according to the number of packets.
Based on this, in the embodiment of the application, before obtaining the real-time traffic data, all historical traffic data at the network entrance of the network segment where the attack target is located in the historical time period are obtained, then DDOS cleaning is performed on all historical traffic data to obtain all historical traffic data without attack traffic, and the proportion of syn-type traffic data in all historical traffic data without attack traffic is determined to obtain the reference proportion. In order to ensure the accuracy of comparison, the traffic data amount in the historical period and the traffic data amount in the real-time period for acquiring all the real-time traffic data are in a positive correlation relationship, for example, the traffic data in the period a of the previous day is calculated to obtain a ratio as a reference ratio of the period a of the day. It is understood that the condition for the reference occupancy is that all traffic arriving at the server is normal user traffic without any attack traffic (in this embodiment, traffic data after four-layer cleaning is regarded as data without any attack traffic), in which case the syn occupancy in each time slot is as shown in fig. 3. In this embodiment, under the condition that the traffic monitoring device starts source authentication, all synflood attacks are intercepted by the DSLB device, and then, the traffic cleaned by the DSLB device is attack-free. Therefore, the syn ratio of the output interface flow after statistical cleaning can be used as the reference ratio.
As can be seen, in the embodiment of the present application, all real-time traffic data at a preset network position between an attack source and an attack target are obtained first; the preset network position is any position between the attack source and the attack target except for a network link of a network segment where the attack target is located; then determining the target ratio of syn type flow data in all real-time flow data, judging whether the target ratio exceeds a reference ratio, and if so, controlling the flow of all real-time flow data; and the reference proportion is the proportion of syn type traffic data in all historical traffic data without attack traffic at the preset network position in a historical period. According to the method and the device, the real-time flow data of the incoming attack target is monitored at the network position far away from the attack target, namely close to the attack source, and synflood attack is found in the network segment where the attack flow does not reach the attack target, so that network blockage at the attack target is avoided. On the basis, the proportion of the syn type traffic data in the real-time traffic data is compared with the proportion of the normal real-time traffic data to perform synflood attack protection, and a stable network environment is provided.

As can be seen, in the embodiment of the present application, all real-time traffic data at a preset network position between an attack source and an attack target are obtained first; the preset network position is any position between the attack source and the attack target except for a network link of a network segment where the attack target is located; then determining the target ratio of syn type flow data in all real-time flow data, judging whether the target ratio exceeds a reference ratio, and if so, controlling the flow of all real-time flow data; and the reference proportion is the proportion of syn type traffic data in all historical traffic data without attack traffic at the preset network position in a historical period.
