Design And Implementation Of The Technology For Detecting And Blocking Devices In LAN

Current computer and network technology rapid development,people's life and work more and more dependent on the network and computer terminal equipment,but with the development of network and computer terminal equipment and popularization,various depends on the network attack and computer terminal's behavior,also in serious threat to people's property security,information on how to prevent and stop using the computer and network espionage behavior research has a very urgent practical significance.This article is based on how to perfect the LAN environment terminal equipment management as the background,introduced based on ARP packet technology as the core network equipment detecting and blocking technology related design and research results.This paper mainly completed the following 3 aspects:i.In view of the current local area network(LAN)environment and related network security defense measures,in based on the research of the SNMP/ARP network protocols such as basis,put forward and realized a kind of based on ARP cache and ARP packet complete terminal equipment to detect and block technology;ii.There may be multiple for larger LAN subnet,MTV architecture using the Django framework,this paper designs a system architecture,the pattern of "1 + N" can implement unified management platform and multiple subnet system deployment.iii.In this paper,This article will detect and block related technology,the design of the transition,and by using the python language and encapsulation of modular design,the system designed in this paper can be similar to the transition in the multiple subnet environment deployment and use,control of enterprise local area network(LAN).The risk in the technology and architecture design of local area network(LAN)equipment controls have higher practical value.
