Abstract

Recent work on securing the Network Coordinate (NC) service attempts to defend attacks based on nodes' past behavior and activities. They detect malicious nodes only after attacks occurred. In order to secure NC system before malicious nodes mount attacks, we propose a social-link defense system for NC service--Sniper. We are able to provide NC system with trusted neighbors (landmarks) using social-link filtering technique. Our preliminary results demonstrate that Sniper can protect NC system successfully before they are attacked by malicious nodes.
