Design graduate thesis- with the anti-virus network technology continues to develop, a lot of Web-based services, network security issues have become increasingly important. ACL or access control lists, it is work in the OSI Reference Model for three more equipment, the data packet through the third, four of Baotou information according to the rules, to determine whether the transmitted data packets. Based on ACL network virus filtering technology will be able to better protect users from the outside world LAN virus interference is a relatively good small and medium-sized LAN security control technologies. The design focus from the computer network virus with the basic features of the status quo of the development perspective, more in-depth studies to the relevant network security technol
