Deployment
The user of the product should be aware that the unsecure nature of the serial
Modbus protocol exposes the communication between the product and the
control system. Encryption, authentication or integrity of transmitted data are
not provided by the protocol. To prevent equipment to operate in an unsafe or
undesirable manner due to malicious activities the product must be positioned in
a trusted network, strictly limited and in a hosted portion of a network or control
system. The recommendation is also to restrict physical access to the product/
system to only allow authorized people to make changes to the system. Besides,
the user can setup system to trigger alarm when communication is interrupted
(device stops responding) and check if there are any unsafe condition.
