Security And Challenges in Embedded Systems Protecting Against Cyber Threats

Abstract

Cyber-attacks pose an increasing risk to embedded systems, a vital part to many devices. This research looks into the security gaps caused by the resource constraints of these systems and analyzes what protective measures are available and what ones are still to come. It looks into many methods embedded systems can be attacked, including computer virus injections, data theft, and denial of service attacks. In addition, the discussion focuses on known defensive mechanisms that include secure boot, hardware security module, and software-based defenses such as intrusion detection systems. Further, the study examines the limitations to current security approaches and examines further areas of concern, focusing on the necessity for minimal and impactful security defenses that are appropriate for the limited computing capabilities and RAM of embedded systems.
