Brief Announcement: Effectiveness of Code Hardening for Fault-Tolerant IoT Software

Internet of Things (IoT) device software has to be resistant to faults to ensure data privacy and security. In this work, we examine five common software hardening techniques and study their impact on software fault-tolerance and security. We experimentally show that some of these techniques may improve fault-tolerance, while the others can reduce overall security. We offer a guideline for IoT developers seeking to make their software robust, and propose a tool for automatic software fault-tolerance evaluation
