Abstract:In view of the security problems and risks existing in the current water industry control network and the release of national Grade Protection 2.0, this paper puts forward and systematically designs the information security scheme of intelligent water industry control network, which is based on the cloud platform of intelligent water industry control network information security architecture system. Through using cloud platform, it realizes perception and analysis. And through using fifirewall and detection software, it monitors the industrial control network data flflow and the status of workstation software. The scheme solves the safety risks of the original water system systematically. The information security scheme has been demonstrated in the actual water system and achieved the expected results.
