At present, the application of computers has spread to all fields of society. At the same time, computer viruses have brought us great destructive power and potential threats. In order to ensure the stable operation of computers and information security protection, it is necessary to take timely measures to prevent viruses.
With the rapid development of information technology in broadcasting and television systems, various TV stations have successively built and improved digital, networked, intelligent, and informalized broadcasting and television business systems. In current IT system construction, most materials in the broadcasting and television industry are stored using mobile storage methods. When entering the editing and broadcasting network, they are generally connected to PC hosts via USB ports. Since USB media are often used across multiple computers, it is inevitable that they may carry viruses. Once a virus invades the main computer of an editing and broadcasting system, it will quickly spread within the network, causing various risks. In severe cases, this can affect normal editing and broadcasting operations. Therefore, isolating viruses from USB storage media is crucial for non-linear editing networks.
Hunan Shuangln USB Media Security Guard (SLNG-2000) is a USB virus isolation device based on the Linux system. It can detect and isolate viruses by controlling the data transmission of USB mobile storage media, which can effectively prevent the threat brought by viruses carried by files on USB mobile storage to PC in the Intranet.
