Rockwell Automation Warns to Disconnect Devices From Internet

Rockwell Automation has sent an urgent message to all of its customers because of rising geopolitical issues and hostile cyber activity worldwide.

The company is asking that any devices currently connected to the public internet be checked out immediately and shut down if they aren’t meant to do so.

This proactive step is meant to lower the attack surface and lower the risk of harmful cyber activity from outside threat actors who are not allowed to do so.

Rockwell Automation stresses that devices like cloud and edge offerings not made to connect to the public internet should never be set up to connect straight to the public internet.

By cutting off this connection, users can make themselves much less vulnerable to online threats.
