Review of embedded systems security

Abstract

Embedded system security has received less attention when compared with other areas of device security application partly
because of the architecture and their single user nature. They have successfully found their relevance in critical aspects of the
society like, healthcare, transportation, energy, economy with life threatening consequences in most cases if they are
compromised. This paper provides a review of these systems and how best it should be architected. It shows their vulnerability
and the importance of providing adequate security to mitigate against them. It further presents some security concerns in
embedded systems and shows sequence of steps required for security implementation in such systems.
