Abstract
Methods, non-transitory computer readable media, and network traffic manager apparatus that assists with protecting a CPU during a DDOS attack includes monitoring network traffic data from plurality of client devices. Each of the plurality of client devices are classified as a valid device or a potential attacker device based on the monitoring. Next a determination of when CPU utilization of a network traffic manager apparatus is greater than a stored threshold value is made. The CPU utilization of the network traffic manager increases as a number of the plurality of client devices classified as the potential attacker device increases. One or more network actions are performed on the plurality of client devices classified as the potential attacker device to protect the CPU when the determination indicates the CPU utilization is greater than the stored threshold value.
