Snmp-based Security Analysis Subsystem

In recent years,the technology of communication network and communication security is becoming very impartment．These two technologies have a strong influence on our society． In order to help US managing the network system and insure our communication'S security,we have also constituted many criterion of network management including service,protocol and SO on．At present,simple network management protocol(SNMP)is the most important protocol we have using．SNMP help the network manager to find out the fault and correct it．Network manager use process to manage the SNMP client and through the SNMP client the network manager can contact the one or many other SNMP server．SNMP use"fetch-store''mode to communicate the information and every server stores some concept variable and some statistical variable,for example some ARP high-speed catch and IP route table．SNMP define"some finite funerary variable and two-dimensional table(MIB)to store data．SNMP add some faction tO build up security,such as community,USM and VACM．This dissertation is to analyze the Snip'S security and use the store—send concept tO crack the SNMP protoc01．The data which cracked store into the database,and we can use the data to analyze the information,All the description and discuss is based on《The CAD system of SNMP))proj ect．...
