DoS Attacks in IoT Systems and Proposed Solutions

The internet of things (IoT) has been gaining attention in the past decade, and this rapid growth is due to the many different advantages delivered towards achieving a smart world. However, security is one of the biggest challenges, as it builds upon the internet. This article surveys denial-of-service (DoS) attacks that occur in the network layer of IoT systems and the impact on various aspects. The Smurf and SYN flood attacks are briefly discussed along with several distinct DoS attack mitigation methods. Two DoS mitigation technologies implemented by IoT security companies are discussed as a case study.
