3.1 Security

Grundfos connected products must be behind a
firewall or connected to a private network.
If a firewall or private network is not in place, the
Grundfos product may be subject to a cyber-security
risk and becomes vulnerable to an attack or
compromise.
Follow the highly recommended configuration
requirements below. If in doubt, consult an IT
Infrastructure Specialist.
3.1.1 CIM 500
CIM 500 is a traditional network-connected device
and must be placed on a private network behind a
firewall. It must not be connected directly to the
Internet. Also, no TCP/IP ports must be forwarded to
the product. If you need remote access to the device,
you must use technologies such as Virtual Private
Networks (VPNs) to ensure a secured connection.
Consider contacting an IT Infrastructure Specialist to
establish such a solution.
For CIM 500 in mode 4, GRM IP (Grundfos Remote
Management) the firewall must accept connections
initialised by the Grundfos product to the Internet
only (outgoing connections).
