Title: Shiguang Wan: Innovator in Network Security

Introduction

Shiguang Wan is a prominent inventor based in Beijing, China. He has made significant contributions to the field of network security, holding a total of 2 patents. His work focuses on improving the efficiency and effectiveness of intrusion prevention systems (IPS) and URL filtering methods.

Latest Patents

Shiguang Wan's latest patents include an IPS detection processing method and a network security device and system. The IPS detection processing method involves determining whether an internal network device is a client or a server. If the device is a client, the method simplifies the IPS signature rule base to create a corresponding rule base. Conversely, if the device is a server, it simplifies the rule base accordingly. This process generates a state machine based on the simplified signature rules, allowing for efficient IPS detection on flowing-through traffic. His second patent focuses on a method and apparatus for filtering URLs. This method identifies the category of a URL connection request and determines whether it conforms to a predetermined passing policy. If it does, the request is allowed to pass through; if not, it is blocked. This real-time categorization enhances the accuracy of URL filtering.
