Problems solved by technology

[0012] The disadvantage of the second resource adaptation and analysis server DDoS attack defense method in the above-mentioned prior art is: the method uses the controller to verify the source address, and then sends the corresponding flow rules to filter the data packets, increasing the In addition to overhead, it also causes a certain delay
When the controller is under attack, this scheme will not be effectively implemented

Embodiment 1

[0052] The embodiment of the present invention provides a detection and defense method for resource adaptation analysis server DDoS attacks in a smart collaborative network. The decision tree algorithm is used to detect the attack situation, and the weight priority queue is activated to respond to the attack to reduce The impact of the attack provides security guarantees for the smart collaborative network and improves the security and reliability of the smart collaborative network.

[0053] In order to defend against DDoS attacks faced by the resource adaptation analysis server in the smart collaborative network, the embodiment of the present invention proposes a scheme of connection migration, detection based on decision tree and weight priority queue defense.

[0054] The processing flow of a DDoS attack defense method for a resource adaptation analysis server in a smart collaborative network provided by an embodiment of the present invention is as follows: Figure 4 As shown, in...

Embodiment 2

[0092] This embodiment provides a schematic diagram of an example in which a resource adaptation analysis server in a smart collaborative network performs DDoS attack detection and defense. Image 6 As shown, the legitimate user is the service requester and normally initiates the service request. Attackers A, B, and C respectively forge a large amount of unknown traffic to initiate DDoS attacks on the resource adaptation analysis server. In the DDoS defense of the resource adaptation analysis server, the present invention is divided into three stages in total. The first stage is the resource adaptation analysis server protection stage, applying the connection migration method, using the cache server as a proxy, caching and forwarding request packets, and limiting the forwarding rate; the second stage is the collection and detection of traffic characteristics to prevent DDoS attacks Judgment; the third stage is attack defense, differentiated forwarding request packets, and improv...

Abstract

The invention provides a resource adaptation resolution server DDoS attack detection defense method in a smart collaborative network. The method comprises the following steps: when a data packet transmission condition in the smart collaborative network conforms to a connection migration condition, migrating the connection between a network component and the resource adaptation resolution server toa cache server, and connecting the cache server to the resource adaptation resolution server; receiving and caching a service request packet sent to the resource adaptation resolution server by the network component by the cache server, and detecting whether the resource adaptation resolution server is subjected to the DDoS attack according to a feature tuple of the service request packet by using a decision tree algorithm; and after detecting the DDoS attack, forwarding the service request packet in a differentiated way by using a defense strategy based on a weight priority queue. Accordingto the resource adaptation resolution server DDoS attack detection defense method in the smart collaborative network provided by the invention, a binary tree branch is established by using the decision tree detection algorithm and combining a plurality of feature properties, and feature extraction is carried out on whole network service request information, thus the attack state can be judged moreaccurately, and defense measures can be taken in time to alleviate the influence brought by the DDoS attack.

Description

Technical field [0001] The invention relates to the technical field of network security, in particular to a DDoS attack detection and defense method for a resource adaptation analysis server in a smart collaborative network. Background technique [0002] Since the emergence of the Internet in the past few decades, it has had a huge impact on the development of human society. However, with the rapid development of the Internet, the traditional Internet architecture has gradually exposed scalability, mobility, security, manageability, controllability, and green energy conservation rooted in original design ideas due to its static and rigid characteristics. Problems have caused it to fail to meet the communication needs of future networks such as "high speed", "high efficiency", "smart", and "energy saving". At the same time, the fully distributed architecture of the traditional Internet makes network management intricate, and this complexity also leads to the vulnerability of the ...
