4. MODBUS/TCP
• The MODBUS/TCP protocol (port TCP/502) is an instrumentation protocol designed to exchange data
between locally connected devices like sensors, I/O modules, controllers etc. From it’s nature it does not
contain any kind of security – neither encryption nor authentication. Thus it is intended to be used only in closed
private network infrastructures.
• Avoid exposing the port TCP/502 to the public Internet.
5. SNMP
• The SNMP protocol (port UDP/161) version 1,2 is not encrypted. Thus it is intended to be used only in closed
private network infrastructures.
• Avoid exposing the port UDP/161 to the public Internet.
