$$\mu $$ Shield

Abstract

Embedded devices are playing a major role in our way of life. Similar to other computer systems embedded devices are vulnerable to code-reuse attacks. Compromising these devices in a critical environment constitute a significant security and safety risk. In this paper, we present µShield, a memory corruption exploitation mitigation system for embedded COTS binaries with configurable protection policies that do not rely on any hardware-specific feature. Our evaluation shows that µShield provides its protection with a limited performance overhead.

“…Since embedded devices run a real-time operating system, we choose for the virtual machine VM1 the QNX Neutrino 7.0 real-time operating system [1] . The QNX operating system is a highly dependable, industry-grade operating system that is utilized in more than 175 million cars worldwide [2] , and in different industrial Programmable Logic Controllers (PLCs) and control systems [3] .…”
