MitigationDisconnect the engineering workstation from external networks (e.g., the internet or corporate LAN) to reduce exposure. MitigationUse only trusted, dedicated internal networks or air-gapped systems for device communication. MitigationRestrict both physical and logical access to authorized personnel only. MitigationConfigure whitelisting so that only trusted, pre-approved applications are allowed to run. Block any unauthorized software. MitigationUse antivirus or EDR tools and configure host-based firewalls to block unauthorized access attempts. MitigationEnable and regularly review system logs to detect suspicious or unauthorized activity. MitigationMaintain secure, tested backups of the PLC and its configurations to minimize downtime in case of an incident.
