In today's world, the integration of various computing devices and embedded systems is creating a giant network that popularly termed as internet things (IoT). Although, IoT has lot business opportunities, but its open distributed nature makes it vulnerable to many cyber attacks. An intrusion detection system (IDS) responsible for monitoring detecting malicious activities in any or network. However, traditional IDS methods require modification enhancement implementation largely due usage specific protocols stack limited availability computational resources, memory space, power these devices. this paper, we propose lightweight resource-constraint by using concept Benford's law, flow size difference, linear regression. We have done extensive experimentation benchmark NSL-KDD dataset shows very positive results.
