Currently, the private cloud Technology in cloud computing has been used in the enterprise's LAN, and security risks also occur from time to time, in this way, cloud security has become a major technical issue for enterprises to study. Many anti-virus software manufacturers have now launched cloud anti-virus software. In the concept of "cloud anti-virus, some cloud security knowledge is summarized through study and research, which is applied in LAN and summarized as follows. 1. Analyze the Local
