With a developing number of cases of data security-penetrates, there is an incredible requirement for endeavors towards making sure about electronic frameworks. Embedded systems are omnipresent frameworks that are used to catch, store, control, and access delicate information. Embedded systems aid humans to direct a suitable life and it is widely utilized in electronics, communication, home applications, aviation, health care, and many more. The security of these frameworks presents a few techniques and intriguing security challenges. In the current scenario, integrating security in an embedded system had become the main anxiety. So, there is a need to intend and establish techniques that can treat the attacks in the best manner. We project a technique to incorporate security modeling into the design of an embedded system. In this paper, different security needs, attack technologies, and treatments for such attacks have been reviewed and analyzed.
