| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | A network defense scheme for an Internet Service Provider (ISP) network is presented. In this scheme, the ISP cooperates with users to filter attack packets or limits their rate. ISPs acquire configurations of filtering and intrusion detection functions which reflect user security policy obtained from user equipment such as Broad-band Routers (BBRs) and PCs. Next, aggregate rule is created from them. Finally, the ISP filters attack packets or limits their rate according to the aggregate rule. ISPs and users take countermeasures to deal with DDoS attacks and propagation of worms separately. The countermeasures of users that filter unnecessary packets by firewall function and IDS function in the BBR cannot mitigate bandwidth usage of these attack packets. On the other hand, countermeasures of ISPs that use the DDoS countermeasure system cannot mitigate the waste of network resources caused by these attack packets. ISPs cannot intercept attack packets without user permission even if the attack is detected by the system. This scheme makes it possible for users to mitigate bandwidth usage of these attack packets on their access lines by providing their security policies to their ISP. Then, The ISPs become able to control the waste of the network resources by not forwarding packets unnecessary to the users. We analyze default configurations of popular BBRs and verify the basic model of this scheme based on those configurations. | |
