Internet-of-Things (IoT) devices are ubiquitous and growing rapidly in number. However, IoT manufacturers have focused on the functionality and features of the devices and made security an afterthought. Since IoT devices have small memory capacities and low-power processors, many security firms have not been able to develop anti-malware software for these devices. Current IoT security solutions are heavy and unreliable. We have to developed a lightweight IoT security solution that uses hacker tools against the hackers-in essence, a vaccine for IoT.
