This study suggests a firewall management method using a virtual server in order to allow a manager equipped with a smart phone not only to detect and prevent security threats but also to control firewalls anytime, anywhere. Recently, hackers’ threatening over security is constantly increasing, but companies or institutions operating a small PC server are exposed to a serious threat on security as they cannot afford to maintain manpower that can control it for 24 hours. As a solution for it, this study suggests a way to provide stable services and also save time and money by detecting an illegal access or intrusion at an early stage and reporting it to the server manager in a remote place via a smart phone so as to cope with it properly. For the solution proposed here, this researcher has designed and realized a system which conducts a pattern matching inspection on the packet using the virtual server and Aho-Corasick algorithm to monitor and detect an intrusion and can realize prompt safety management in a remote place with the system control that is realized by an android app.
