The platform for communication visualisation and modelling of SCADA system security policies is a dedicated solution for managing security in process environments, enabling security experts to gain deeper insight into and gain a better understanding of all relevant communication flows taking place within these environments. Visualisation of network communication, defining the communication matrix and establishing a communication baseline enable security experts to obtain fresh insight into the often immense and ambiguous traffic flows in complex geo-distributed network environments, thus facilitating the creation of new security policies and rectifying existing ones.
