Abstract

The invention discloses an abnormal flow detection method based on a GBR image. The method comprises the following steps: S1, converting flow data into a visual GBR image; s2, storing the GBR image data in a distributed file system; and S3, based on a distributed file system, training a sub-convolutional neural network model for each data block of the GBR image data by using an Apache Spark framework to complete detection of abnormal traffic. According to the abnormal traffic detection method, the original network traffic is converted into the grayscale image, the traffic information is reserved, and then the two feature vectors are selected to form the GBR image, so that the false alarm rate of detection is reduced. The distributed file system and the sub-convolution neural network modelare used, the problems of huge calculation and slow convergence of a detection method are avoided, the capability of detecting unknown attacks is achieved, and the detection accuracy is high.

Description

technical field [0001] The invention belongs to the technical field of network traffic detection, and in particular relates to a GBR image-based abnormal traffic detection method. Background technique [0002] In recent years, with the rise of the concept of artificial intelligence, more and more machine learning has been applied to the construction of abnormal traffic detection systems, resulting in many valuable network security technologies. Most of these systems are constructed by collecting network traffic first, performing feature extraction, and then using data mining technology to perform pattern matching, so as to identify currently known attacks in an offline manner. These abnormal traffic detection systems are of high value in the promotion of network security, but there are deficiencies such as slow speed of establishing the system, complex feature extraction and high cost of resource occupancy. Based on the above situation, the present invention proposes a meth...
