Usable Intrusion Detection & Response on Personal Mobile DevicesDescription
Users of personal mobile devices are susceptible to physical intrusion by socially close adversaries. The goal of this project is to develop and evaluate passive modes of security, that can accommodate the social relationships between parties. Unlike unlock authentication, which is an active defense against physical intrusion, passive defenses aim to primarily provide awareness, traceability, and recovery from intrusions; and to only secondarily engage counter-measures like blocking access. In sensitive computer systems, passive security is embodied in Intrusion Detection and Response (IDR) systems. To end-users, however, parallel capabilities remain unavailable, or lack security and usability validation, despite the severe privacy implications of intrusions. We thus envision a mobile IDR which is usable by individuals with no technical training; which can detect suspicious activity based on semantics of intrusion behavior; and which can respond to threats per their importance.
