Mitigation of IoT Device Based DDoS Attacks (Using Blockchain)
Keywords:Internet of Things (IoT) , Distributed Denial of Service(DDoS), Blockchain, Ethereum, Smart Contracts
Internet of Things(IoT) refers to the connection or interconnection of smart objects or devices sharing data and/or information. In the world of today, devices are being made smart which makes internet of things to emerge as an area of incredible impact, potential and growth. Therefore, the rapid development of internet of things also brings about threat of insecurity. There is difficulty in the securing of private data and information as the internet of things (IoT) is being vulnerable to various attacks. In this review article, we focus on the Distributed Denial of Service(DDoS). This is an attack initiated by the attacker to disrupt the authentic user from using the required services and also make network resources unavailable thereby consuming bandwidth. This paper aims at reviewing different methods and articles used to mitigate these attacks with great focus on blockchain variant used with smart contracts. This blockchain variant known as Ethereum is integrated with the Internet of Things devices and prevents the rogue devices and DDoS attacks from gaining access to the server. The research methodology is based on qualitative analysis where various literatures is being reviewed based on IoT devices and DDoS attack mitigation. This paper will be of benefit to individual in the cyber security field.
