This paper analyzed current network security of the small and medium-sized enterprise, and discusses the existing problem in small and medium-sized enterprises and the existing technology, and network security and management. Finally the paper points out the network security and proposed network security model with four layers (application layer, system layer, network layer, physical layer) network defense in depth security solutions and network security deployment plan based on the MPDRR (safety management, safety protection, safety inspection, safety, security response recovery).

Security Problem

With the “Internet +” era of arrival, the major colleges and universities are in the construction of the wisdom of the campus, students and teachers living with the campus network is more and more closely related, Campus network security has become the protection of the wisdom of the campus construction. Campus network security issues become increasingly serious; a single security protection has been unable to meet the current security needs. This paper analyzes the major security threats facing the campus network, and presents the campus network security protection measures from the physical layer, network layer, system layer, application layer and management of five aspects, thus constructing the campus network's overall security defense system. The system has multiple security protection for Campus Network, thus improving the security of the campus network.

Security Problem

this article from the various security threats facing the computer network, systematically introduces the network security technology. And in view of the campus network security issues, firstly analyzes the hidden dangers to the safety of network system in colleges and universities, and then from the build two aspects of security defense system and strengthen the safety management design of the campus network security policy. This paper study, the first thing I learned the main threat to the network security problem, and use the knowledge of security network security problems are analyzed. Secondly, based on the research of the network technology, campus network will also be faced with the security threat. Finally, the idea of established with P2DR model to establish campus network security defense system. And it is concluded that the building of a set of effective network security defense system is the solution Campus network main threats and hidden trouble of necessary ways and measures.

Mobile Target

Mobile target defense (MTD) is a research hotspot in the field of network security. The decision method of network defense based on game theory is an important technique to guide MTD to make the optimal defense behavior in different network environments (GT-MTD). A lot of related work has been put forward in this field. In this paper, we focus on the scope and field of GT-MTD, systematically introduce the application scenarios of MTD in combination with four different game theory models of classical games (static games, signal games), Markov games, differential games or evolutionary games, and put forward the future development direction. There are some new views and explanations on the research of GT-MTD.

Individual Attack

<span>To secure a wealth of data traversing the computer network at your fingertips is compulsory. But when attack arises at various parts of the network it is difficult to protect, especially when each incident is investigated separately. Geography is a necessary construct in computer networks. The analytics of geography algorithms and metrics to curate insight from a security problem are a critical method of analysis for computer systems. A geography based representation is employed to highlight aspects (on a local and global level) of a security problem which are Eigenvalue, eccentricity, clustering coefficient and cliques. Network security model based on attack undirected geography (AUG) is familiarized. First, analysis based upon association rules is presented then the attack threshold value is set from AUG. The probability of an individual attack edge and associated network nodes are computed in order to quantify the security threat. The simulation is exploited to validate that results are effective.</span>
