Abstract

Most of intrusion detection systems are usually reviews only on the header of a packet, while the payload is ignored. To prevent an unknown attack from Internet it needs IDS that is able to analyze the header and also the payload. In this final project will be designed and implemented a network intrusion detection system that has the ability to detect an attacks by analyzing the payload of a packet by using the Outlier method. By performing normalization on the selected features, then calculate the standard deviation to determine the lower limit and upper limit. Data that are beyond the range of lower and upper limits will be considered as an outlier. It is also used a keyword payload to determine whether the payload is included an attack or not. Expected outlier method is capable to determine attacks through packet analysis with accurate features. And became one of the methods used in the IDS software among other methods that have been made or are being developed. Keyword : IDS, payload, outlier, tcpdump
