Modbus Security - New Protocol for better system control

The Modbus organization has published a new Modbus Security protocol standard used for security control and verification of systems controlled by the Modbus protocol. The new protocol brings robustness and thus greater security and length of data transmission without interference. The protocol also supports the transmission of role-based access control information using an X.509v3 extension to authorize the request of the Client. Modbus Security will use a new port; traditional Modbus uses port 502. The new Modbus Security protocol will utilize port 802.
