Abstract: Based on the State Grid Unified Application Platform as the carrier, this paper proposed an extensible access control policy. For a long time, the combination of electric power enterprise internal environment and traditional access control are very inadequate. The traditional access control model on the current unified platform access and control permissions interaction problems is almost blank. Therefore, this paper puts forward an improved access control model. The model has solves some key problems of access control in State Grid Unified Application Platform , such as specific role division, interaction between roles, permissions delivery, senior role inherited permissions unlimited scale-up, and permissions linkage.

Abstract: The rise of Massive Open Online Course (MOOC) has enabled open courses to overcome the shortcomings of its traditional mode. Interactions and communications have become important elements in online open courses right now. Cloud computing is a new platform for MOOC development, which is extension of the distribution computing, the parallel computing and the grid computing, settling the problem of various resource sharing. In this paper, the design of cloud computing environments is showed with the cloud computing system structure, network security analysis of cloud computing, and map-reduce program mode, which forms the model of cloud computing environment.

Abstract: As the second line of defense, intrusion detection is the necessary means of getting the high survivability. Intrusion detection technology and its classification is described in this article. And based on the features of Ad Hoc network, the existing new network intrusion detection technology and its characteristics suitable for Ad Hoc network are summarized.

Abstract: With the rapid development of network technology, the network security related threats are more and more serious at present. To guarantee the security of the network, now the main defense technology is static, but the static defense technology don’t change with the corresponding preventive measures change and unable to attack intention and attack strategies. Based on the analysis of the current situation, this paper mainly analyses the dynamic non cooperative game theory, and applied the theory to network security prevention, and achieved good results.

Abstract: Currently, the main network security mechanisms (such as firewall, intrusion detection, and vulnerability scanning) cannot prevent malicious attacks absolutely from the public network. Therefore, how to ensure the security of the information in the private network is a hot topic. In this paper, a network physical isolation system is designed based on private protocol, in which internal and external networks are physically isolated during the data transmission. Thereby, the security of network information is protected and the network security problems can be solved effectively through this isolation system. This isolation system can be applied in high security network environment such as government departments and business units, etc.

Abstract: As the second line of defense, intrusion detection is the necessary means of getting the high survivability. Intrusion detection technology and its classification is described in this article. And based on the features of Ad Hoc network, the existing new network intrusion detection technology and its characteristics suitable for Ad Hoc network are summarized.

Abstract: This paper introduces a middleware ICE and network security management technology, and points out that the ICE in the distributed network security management system advantage. And then it puts forward a multilevel network security management system using ICE middleware technology, multilevel security management system establishment of wide area network, a vertically integrated, unified, which can carry out security event monitoring, centralized acquisition and processing, security policy management, security alarm and alarm disposal and attendance management.

Abstract: This paper first describes the basic theory of BP neural network algorithm, defects and improved methods, establishes a computer network security evaluation index system, explores the computer network security evaluation method based on BP neural network, and has designed to build the evaluation model, and shows that the method is feasible through the MATLAB simulation experiments.

Abstract: The paper takes network security guard as a dynamic process, each link of the network security technology throughout the entire firm information operation, namely design an integrated network security system, which includes firewall system, VPN system etc.. The system can meet the requirements of network security and the goals of design network security.

Abstract: IP traceback can be used to confirm locations of attackers, stop on-going attacks, and take legal actions against attackers, and then impede attackers. This paper describes the background where IP traceback problem generates, and presents what the functions of IP traceback are. Furthermore, this paper classifies existing IP traceback methods and analyzes advantages and disadvantages of each method. In addition, future researches on IP traceback are proposed. This paper is of valuable reference for network researchers and engineers to be engaged in the further study on IP traceback.
