What is a Data Breach?
A data breach is an intrusion into an organization’s system, network, or database, by an outside or internal entity, resulting in unauthorized access to confidential or secured information.
Tips to prepare for a data breach
Implement multifactor authentication for access to the operational technology (OT) network whenever applicable.
If you require remote access, implement a firewall and/or virtual private network (VPN) in front of the PLC to control network access. A VPN or gateway device can enable multifactor authentication for remote access even if the PLC does not support multifactor authentication.
Create strong backups of the logic and configurations to enable fast recovery.
Keep your systems updated with the latest versions by the manufacturer.
