At present, most Trojan detection methods are based on the features of host and code. Such methods have certain limitations and lag. This paper analyzes the network behavior features and network traffic of several typical Trojans such as Zeus and Weasel, and proposes a Trojan traffic detection algorithm based on machine learning. First, model different machine learning algorithms and use Random Forest algorithm to extract features for Trojan behavior and communication features. Then identify and detect Trojans' traffic. The accuracy is as high as 95.1%. Comparing the detection of different machine learning algorithms, experiments show that our algorithm has higher accuracy, which is helpful and useful for identifying Trojan.

Low accuracy and slow speed of predictions for cyber security situational awareness. This paper proposes a network security situational awareness model based on accelerated accurate k-means radial basis function (RBF) neural network, the model uses the ball k-means clustering algorithm to cluster the input samples, to get the nodes of the hidden layer of the RBF neural network, speeding up the selection of the initial center point of the RBF neural network, and optimize the parameters of the RBF neural network structure. Finally, use the training data set to train the neural network, using the test data set to test the accuracy of this neural network structure, the results show that this method has a greater improvement in training speed and accuracy than other neural networks.
