A Study On Network Security Of Information Sharing In Supply Chain

In the process of message transmitting among supply chain enterprises there exists Bullwhip Effect, and carrying out the information sharing among supply chain enterprises can relieve the Bullwhip Effect in the process of message transmitting among supply chain enterprises. The technology to carry out the information sharing mainly is computer network technology, but in the computer network there exists network security problems, This paper is studying the network security problems on information sharing in supply chain.This paper firstly starts from the Bullwhip Effect among supply chain enterprises and points out that the information sharing among supply chain enterprises can relieve the Bullwhip Effect. Then for solving the network security problems, such as Password Breaking, Network Sniffer, Port Scanning, Buffer Overflow Attack, Denial-of-Service Attack, Network Monitor, etc, which exist in the process of information sharing among supply chain enterprises, this paper analyzes these attacks detailedly. Especially, as an important example, the analysis to DoS (Denial-of-Service) Attack which indicates that the network attack is not difficult to prevent,and this paper gives the AHP(The Analytic Hierarchy Process) analysis and fuzzy analysis about several IP traceback of DoS attack, meanwhile, finally this paper gives the protections about other network attacks separately and an Information Sharing VPN-Solution to supply chain enterprises based on Internet/Intranet. By the study in this paper, it is expectant to do some active contribution in the network security problems on information sharing in supply chain.
