An In-Depth Analysis on Adoption of Attack Mitigations in Embedded Devices

Ruotong Yu (Stevens Institute of Technology, University of Utah), Yuchen Zhang, Shan Huang (Stevens Institute of Technology)

Embedded devices are ubiquitous. However, previous research puts little effort on understanding the adoption of common attack mitigations in embedded devices, creating a knowledge gap on embedded security. To bridge this gap, we present an in-depth study by evaluating the adoption of common attack mitigations on embedded devices. In this paper, we summarize our effort on building a high-quality dataset, accurately evaluating kernel-level and user-space attack mitigations and inferring the factors contributing to the absence of attack mitigations. The dataset contains the firmware images from 38 real world vendors range over a decade, reflecting the up- to-date ecology of embedded security. The lack of enough adoption of attack mitigations exposes threat in the coming IoT era as the situation is not improving over time. We envision that understanding the potential factors leading to the lack of adoption of attack mitigations will shed light on improving the security of embedded devices in the future.
