It is widely recognized that security is a concern in the design of a wide range of embedded systems. The promise of universal connectivity for embedded systems creates increased possibilities for malicious users to gain unauthorized access to sensitive information. This paper presents an overview of the need for security in the design of embedded systems as they are potent, autonomous and highly connected. With the emerging growth of embedded systems ranging from low-end systems such as PDAs, networked sensors and smart cards, to high-end systems such as routers, gateways, firewalls, and web servers, security of embedded systems became a paramount issue. Attacks on these systems are getting more and more sophisticated. Hence, it is essential that these devices have good protection against attacks.
