Research on Redirect Technology Based on Interest Association Rules in NAT

For lack of resources for IP address and the Network attack become diversity, the NAT technology is used for address extension. So, the requirement of Network security is improved. This paper mainly research on the security policy of NAT, and proposes Intrusion Redirect, protection of the Network effectively. Base on Apriori mining, proposes Interest association rules for the IDS Intrusion log database mining, the threat network access will be redirected to a specific environment, through the highly interactive among the access rules database and firewall rules, and IDS log database, the network defense initiative has improved, to achieve the double protection for the network with the NAT and Firewall technology.
