With the development of computer network and rapid popularity of Internet, network information security has become the focus of safeguarding national security and social stability. In the network security event, the hacker often can’t successfully intrude into the network by means of a single host / services hacker. With the help of various kinds of "vulnerability" generated bydifferent relationship existing in multiple point multiple host, the hacker can achieve the purpose of network intrusion. Therefore one important aspect of network security is after obtaining the vulnerability of the network information, considering a combination of multiple exploits and analyzing the attack path of network penetration attacks that the attacker may take.

It is possible to improve the safety performance of the radio network by accurately identifying the attack signal path in the radio network information. When the attack signal path identification is carried out, it is necessary to calculate the vulnerability of the attack signal path, obtain the time series sample set of the net-work attack path, train the sample set for different vulnerabilities, and complete the path recognition.The traditional method is to establish the attack graph model. It cannot calculate the vulnerability of the attack signal path and cannot carry out the training, which leads to the limitation of the path recognition and the low efficiency. An improved identification method of attack signal path in radio network information with improved attack graph is proposed. Firstly, the attack map of the traditional method is transformed according to the theory of graph theory, and the concept of vulnerability factor is introduced into the improved attack graph. The vulnerability of the attack route is improved, and then the sliding time window is used to construct the network attack path recognition Time series sample set, Ada-Boosting method is used to train the sample sets with different vulnerabilities,and the regression matrix is obtained by using the training results. Finally, the attack signal path identification in the radio network information is completed.The simulation results show that the improved method has high accuracy and can guarantee the smooth operation ofthe radio network.

In computer network, security of the network is a major issue and intrusion is the most common threats to security. Cyber attacks detection is becoming more enlightened challenge in detecting these threats accurately. In network security, intrusion detection system (IDS) has played a vital role to detect intrusion. In recent years, numerous methods have been proposed for intrusion detection to detect these security threats. This survey paper study examines recent work in the topic of network security, machine learning based techniques as well as a discussion of the many datasets that are commonly used to evaluate IDS. It also explains how researchers employ Machine Learning Based Techniques to detect intrusions
