Activity
Control and visualisation units are designed to control machines and unable to fend off external attacks.
When running these units in
publicly accessible networks
, you should therefore ensure that your machine is
protected by a sturdy firewall. Use an intelligent router with its own firewall which keeps the network of your
machine separate from the web or enterprise network.
NOTE
Unauthorised access to the computer
Controller failure and data loss
Integration in networks granting public access requires the user to take appropriate
measures aimed at preventing unauthorised access.
