NETWORK SECURITY
When operating Excel Web in IP networks, either private (e.g., VPN) networks must
be used or protection against the open Internet (e.g., with external firewalls) must be
ensured.
Honeywell hereby expressly states that the Excel Web controller is not inherently
protected against cyber attacks from the Internet and that it is therefore intended
solely for use in private, protected networks.
Unprotected Internet connections can expose the Excel Web controller to cyber
attacks from third parties who can then damage it and connected facility com-
ponents or cause them to malfunction, or who can misuse it for illegal purposes
for which the operator may then be held liable.
When directly connected to the Internet, the Excel Web controller automatically
becomes a potential target for cyber attacks. Corresponding protective measures
are therefore essential if safe and reliable operation is to be ensured.
If it is not necessary for the Excel Web controller to be accessible from the Internet,
it should be isolated from the Internet via a suitable firewall.
If it is necessary for the Excel Web controller to be accessible from the Internet (e.g.,
in order to perform remote maintenance), the use of a coded VPN connection is
indispensable. Suitable VPN routers are available from numerous third-party
manufacturers in a wide variety of designs, for operation at 230 V or 24 V.
