Network Security Situation Based on Time Factor and Composite CNN Structure

In order to solve the problem of low accuracy of traditional network security situation awareness research methods in the case of complex network information, combined with deep learning, this paper proposes a network security situation assessment model based on time factor and composite CNN structure, which combines volume integral solution technology and deep separable technology to form a four layer series composite optimal unit structure.The one-dimensional network data are transformed into two-dimensional matrix and loaded into the neural network model in the form of gray value, so as to give full play to the advantages of convolution neural network.In order to make full use of the time-series relationship between data, time factor is introduced to form fusion data, which makes the network to learn the original data and fusion data with time-series relationship at the same time, the feature extraction ability of the model is increased, the spatial mapping of time-series data is established by using time
