Physical Memory Attacks and a Memory Safe Management System for Memory Defense (2403.08656v1)

Abstract: Programming errors, defective hardware components (such as hard disk spindle defects), and environmental hazards can lead to invalid memory operations. In addition, less predictable forms of environmental stress, such as radiation, thermal influence, and energy fluctuations, can induce hardware faults. Sometimes, a soft error can occur instead of a complete failure, such as a bit-flip. The 'natural' factors that can cause bit-flips are replicable through targeted attacks that result in significant compromises, including full privileged system access. Existing physical defense solutions have consistently been circumvented shortly after deployment. We will explore the concept of a novel software-based low-level layer that can protect vulnerable memory targeted by physical attack vectors related to bit-flip vulnerabilities.
