Security is becoming a major concern in embedded system designing and development. This paper surveys security requirements, attack techniques and will review countermeasures for these attacks. Use of embedded systems in diverse and complex applications have relentless importance of secure and fault tolerant system. It is essential for embedded device's to secure sensitive information, ensuring availability and providing secure communication system. Reliability is directly coupled with security in embedded systems thus an unsecured system is also an unreliable system.
