| Summary: | 碩士 === 東海大學 === 資訊工程與科學系 === 97 === In recent years, networks are essential particularly for our daily life. More and more people access useful information, receive e-mail, purchase high-tech products, etc., through websites. However, when we enjoy network convenience, networks on the contrary also conduct threats for us, like Denial of Service (DoS) and Distributed Denial of Service (DDoS), resulting in bringing us inconvenience or financial loss, e.g., enterprises or companies’ huge amount of financial loss or missing their business opportunities. IDSs can protect network systems. But they often suffer from losing their detection effectiveness and capabilities when processing enormous network traffic. In this article, we proposed an intrusion prevention system, named Cumulative-Sum-based Intrusion Prevention System (CSIPS) which detects malicious behaviors, attacks and distributed attacks launched to local and remote servers/hosts based on intrusion detection techniques and Cumulative Sum (CUSUM) algorithm. Experimental results show that CSIPSs can carry out a higher security level for a united defense environment.
