Preventing undesirable online access attempts
WARNING!
SIGRIST instruments are equipped with an integrated web user interface and
Modbus TCP interface, thus offering state-of-the-art administration and control
possibilities. However, if these are connected directly to the Internet, then any In-
ternet user can in principle access your instrument and change the configuration.
Please note the following points to prevent this:
▪
Never connect the instrument directly to the Internet.
▪
Operate it behind a firewall and block access to the instrument.
▪
Only connect to branch offices via VPN.
▪
Change the standard password on commissioning.
▪
Always keep up to date with the latest changes regarding Internet security so that you
can react promptly in the event of alterations.
▪
Install the latest updates immediately (also for the router and firewall).
