On the effectiveness of internal patching against file-sharing worms

摘要: File-sharing worms have been terrorizing Peer-to-peer (P2P) systems in recent years. Existing defenses relying on users' individual recoveries or limiting file-sharing activities are ineffective. Automated patching tools such as Microsoft Windows Update and Symantec Security currently the most popular vehicles for eliminating containing Internet worms, but they not necessarily best fits combating P2P which propagate within a relatively smaller community. In this paper, we propose complementary P2P-tailored system utilizes existing mechanisms to internally disseminate security patches those participating peers timely distributed fashion. Specifically, examine effectiveness of leveraging file downloading searching process notify vulnerable end hosts surging push corresponding updates these hosts. We show through in-depth analysis extensive experiments that both methods scalable effective worms.
