Ensuring data security in Ethernet networks
When accessing via the Internet, there is a risk that unauthorized users may access and
manipulate the data or devices in your system.
• Take suitable protective measures (e.g. set up a firewall, close network ports that are not
required, only enable remote access via VPN tunnel).
