Abstract

Internet of Things (IoT) can send and receive data over a network without requiring human-to-human or human-to-computer interactions, the use of this technology is very broad from the fields of health, transportation environment, business, and others. Likewise in monitoring water quality, water as an essential substance for every living thing, water needs to be properly maintained. Therefore, monitoring and managing water quality is vital, by applying the Wireless Sensor Network technology developed with IaaS cloud computing services, water quality can be monitored online and in real-time. The reality that occurs with the application of IoT technology which has data exchange traffic has a direct impact on servers, databases, and the results of data collection and monitoring from each station node which will be used as a decision support system in water resources management. As a result, there are security threats involved in implementing IoT technology. This paper offers techniques with catch and drop security methods that can be applied to the TCP / IP protocol in handling attacks on IoT networks in the Water Quality Monitoring System. This method can minimize DDoS attacks at Layer 3 Protocol TCP / IP on TCP and UDP ports. This can stabilize the performance of the Node Gateway
