An industrial system can benefit from a protocol-based firewall by using a protocol converter. Network security has recently taken a primary concern due to the rise of cyber-attacks. Bi-directional conversion will be achieved by a protocol converter, which enables firewall rules to impose restrictions on communication between remote and SCADA. Only valid data requests with mapped connections between the protocols will receive a response. No mapping means will lead to no response. As a result, your network will be automatically protected from unauthorized traffic while yet allowing for critical industrial application communication. Also, the cost-effective integration of current assets into a single SCADA system can be accomplished with the help of a router that has protocol conversion capabilities.
