ABSTRACT

Cybersecurity has become a serious issue in cyberspace due to the increased number of security breaches. Unavailability of the services to the legitimate user is the result of distributed attacks. A Distributed Denial of Service (DDoS) attack is a malicious attempt to disrupt the normal traffic of a focused provider or its surrounding with a flood of internet visitors. Emerging technology makes the cyber realm more critical. The device connected with the internet (IoT devices) is infected with malware and compromised, meaning the device can remotely control the network and make the system unavailable. Establishment of Botnet in a network means remotely controlling a machine for a cyber-attack. The targeted server or service is then flooded with the abnormal traffic, causing Denial of Service (DoS) to the user. This chapter aims to describe the various identification methods of distributed attacks to deal with DDoS.
