And the essence of implementin g E-commerce is the credit standing among the banks, the sellers and the custom ers. But the credit standing in the net ultimately depends on the security of th e network. Firewall is a useful network security technology to keep a network fr om being intruded. The rational use of firewalls can strengthen the security of the E-commence system. Traditional package-filtering firewalls usually rej ect the illegal accesses and admit the legal accesses according to filtering pol icy established by the administrator in advance. But the measures of attacking n etworks are increasing, so ACL (access control list) that is established in adva nce can hardly meet the needs of the rapid development of the network. And the r eal-time quality and sensitivity of traditional firewalls are not satisfied. No w a new model of implementing the expert system to the management of network sec urity is brought forward. The focus of the intelligent packet-filtering firewal l lies on the expert system. The tight combination of expert system and the filt ering method can realize the efficient detection and control of the packages tha t flow through the firewall system.
