In this paper we demonstrate a new impression of intrusion detection system. We use multilevel structure of intrusion detection systems to protect our network. Most of traditional report systems are complicated and hard to manage. In our system, our interface of report system is easy to read and manage. The most important is we use open source software to integrate our system. This can make the cost of intrusion detection system down and make our system flexible. It is convenient to user and network manager. In our system, we can integrate different intrusion detection system and report system into one system. It will become a trend nowadays.
