Abstract
In this Internet of things era, the malicious activity has becoming a problem with the society. But, there not many people that aware the danger of the malicious activity. One of the malicious activity is Distributed denial-of-service (DDos) attacks which is it is a great attacks to network security. This type of attacks are difficult to be quickly detected by low level security. The flood of incoming packets to the machine essentially forces it to shut down, thus the service to the legitimate users is denied. Types of detection can be signature detection or anomaly detection. In this project, DDos detection method by using snort is proposed. By using this proposed, DDos attacks can be effectively detected.
