CPU Load Analysis & Minimization for TCP SYN Flood Detection

Denials of service attacks are well-known as one of the major threats in today's Internet services. Majority VOIP services, DNS servers, online gaming and e-commerce applications are suffering and targeted by hackers using the execution of denial of service attack. Web application attacks and denial of service attacks in distributed architecture is significantly increases day by day. The denial of service attack hampers the load on CPU of web servers during the attack. Therefore, there is a need to minimize the load of CPU after effective attack detection.This paper proposes and implemented denial of service detection framework which consists of packet sniffer, feature extraction, attack detection and output module. The proposed framework detects denial of service attack such as TCP SYN Flood based on threshold and misuse detection. The system is analyzed with the help of CPU load and the load of CPU is minimized after TCP SYN flood attack detection.
