Software Development and Design of Network Security System Under Big Data Analysis

Abstract

To explore the prediction effect of network security situational awareness on network vulnerabilities and attacks under the background of big data, this study constructs a predictive index system based on the network security situational awareness model. Based on the improved cuckoo algorithm, the cuckoo search radial basis function neural network is used to predict the situation. The weight value in the model is determined by the hierarchical analysis method, vulnerability simulation is conducted by Nessus software and network attack simulation is conducted by Snort software, and then the situation is evaluated by a fuzzy comprehensive evaluation method. Finally, Jquery and Bootstrap software is used to develop the system. The results show that the cuckoo search radial basis function model proposed in this study could predict network security situations more accurately than the radial basis function model, cuckoo search back-propagation neural network model, genetic algorithm radial basis function model and Support vector machine model based on particle swarm optimization model.

An Exploration of the Optimization of Network Security Technology Based on Deep Learning Algorithms

“…The computer network security assessment mainly shows the results of security management posture assessment and analysis and prediction [12] . The deep learning algorithms of neural network and convolutional operation are trained on the computer network security data information, and then the prediction results are verified with the actual results, and when the verification results have a very low error with the actual results, the neural network learning and convolutional operation in the context of deep learning are used to assess the current situation of the computer security posture, and then based on the level of the security posture, to formulate effective computer network security management and governance strategies, and ultimately, the security management and management of the network.…”
