Cyberattacks are shifting from traditional IT environments into operational technology (OT). Whereas attacks
once focused on stealing sensitive corporate data, they now increasingly target system availability. Machine
manufacturers and their production processes have become direct targets – whether to steal proprietary know-how
or to carry out acts of sabotage.
The aim: production downtime, loss of efficiency – or, in the worst-case
scenario, complete failure.
Physical security at the machine thanks to the Integrated Key Switch of the mbNET.rokey
MB connect line offers a particularly practical security feature with its mbNET.rokey industrial router, which
includes an integrated key switch directly on the device – providing protection exactly where it’s needed most:
at the machine itself. This physical switch allows the operator to toggle between three clearly defined
operating modes: offline, online, and remote mode.
In offline mode, the router functions solely as a local data gateway and firewall, controlling communication
within the shop floor network. The online mode enables configuration changes and essential firmware updates via
management software – while preventing any external access to the machine network. Only when the key is
physically turned to the Remote position is VPN-based remote access granted to authorized users.
This hardware-based separation offers a major advantage: only authorized personnel on-site can enable remote
access – an effective barrier against unauthorized external intrusion. The visibility and tactility of the key
provide operational clarity: if the router is in Remote mode, it’s immediately recognizable.
Regulatory Frameworks as an Opportunity for Better Security
As cyber threats continue to rise, legislators have laid important foundations to strengthen OT security.
With the RSP firmware 2.17.0, MB connect line expands the functions of
mbNET and mbNET.rokey
to include LAN segmentation. Operators of machine networks and service providers can
now structure and secure their network infrastructure even more precisely
