Problems solved by technology

This method has the following shortcomings: 1. In the face of the impact of high-speed and large-scale data, effective detection cannot be carried out, and the rate of false positives and false positives will be high; 2. Without a high-performance computing platform, it may not be detected in time An attack has been detected or an attack has been detected
This method has the following disadvantages: the high-performance computing capability of a single-chip NetFPGA chip is limited, and when large-scale high-speed data enters the intrusion prevention system, the defense effect is not ideal, performance bottlenecks will occur, and the false positive rate and false positive rate will be relatively high. Not suitable for defending against big data attacks

Embodiment 1

[0039] Such as Figure 1-3 As shown, the present invention includes an intrusion prevention system comprising

[0040] Data packet capture module: responsible for capturing the data packets entering the host and storing them in the database of the data storage module;

[0041] Data storage module: store data in the entire intrusion prevention system;

[0042]Data packet analysis module: analyze the data packets captured by the data packet capture module, reassemble the fragmented data packets, and classify according to the source address, source port, protocol type and data packet size of the data packets;

[0043] Matching filtering module: use the matching filtering algorithm in the matching filter to match and filter the captured data packets;

[0044] FPGA acceleration platform: use the computing characteristics of the FPGA computing system to accelerate the execution speed of the data, packet classification module, matching filter module and neural training module algor...

Embodiment 2

[0052] This embodiment is preferably as follows on the basis of Embodiment 1: It further includes a log analysis module: performing real-time analysis on log files generated inside the host.

[0053] The matching filter module uses the neural network generated by the BP error backpropagation neural network algorithm to match and filter the preprocessed data. BP error backpropagation neural network algorithm is a kind of inverse deduction learning algorithm of multi-layer network. The basic idea is that the learning process consists of two processes: the forward propagation of the signal and the back propagation of the error. The weight adjustment process of each layer of signal forward propagation and error back propagation is repeated, and the process of continuous weight adjustment is also the learning and training process of the network. This process has been carried out until the error of the network output is reduced to an acceptable level, or until the preset number of ...

Embodiment 3

[0058] An intrusion prevention method, comprising the steps of:

[0059] S1: start the intrusion prevention system, the data packet capture module invokes the data packet capture program to capture the network data packets entering the host, and store them in the database of the data storage module;

[0060] S2: the data packet analysis module analyzes the captured data packets, reassembles the fragmented data packets, and discards incorrectly formatted data packets;

[0061] S3: The matching filtering module uses the matching filtering algorithm embedded in the FPGA acceleration platform to match and filter the analyzed data packets according to the feature library, stores the abnormal data packets in the data storage module, and starts the security response module; the matching filtering algorithm It is a BP error backpropagation neural network parallel algorithm, and the neural network generated by the BP error backpropagation neural network parallel algorithm on the FPGA a...

Description

technical field [0001] The invention relates to the field of network security, in particular to an intrusion prevention system and method. Background technique [0002] With the advent of the era of big data, various big data technologies continue to emerge, bringing great convenience to people's social life. At the same time, issues related to the security of big data and the use of big data to carry out network attacks have become increasingly prominent, especially the most threatening APT attack. This has brought great threats to our network environment, especially for large enterprises and important national departments. The detection of APT attacks has also become the key detection object of network detection. Traditional intrusion detection / prevention systems have the disadvantages of high false positives and false negatives. [0003] The current mainstream solution is to use the fusion of multiple defense technologies, such as the combination of firewalls and intru...
