AI-suggested
1. Network Segmentation: Strictly segment industrial control networks from corporate and external networks to limit attacker access to the adjacent network required for exploitation. 2. Access Controls: Implement robust network access controls, including firewalls and intrusion detection/prevention systems (IDS/IPS), to monitor and restrict traffic to the affected modules. 3. Monitoring and Anomaly Detection: Deploy continuous monitoring solutions to detect unusual communication patterns or repeated Forward Close operations that could indicate exploitation attempts. 4. Vendor Coordination: Engage with Rockwell Automation for timely updates and patches; prioritize testing and deployment of firmware updates once available. 5. Incident Response Preparedness: Develop and rehearse incident response plans specific to ICS disruptions, including fallback procedures to maintain operational continuity. 6. Configuration Hardening: Review and harden device configurations to disable unnecessary services or features that could be leveraged in the attack. 7. Physical Security: Ensure physical security controls to prevent unauthorized local network access to the devices. 8. Employee Training: Train operational technology (OT) personnel on recognizing and responding to potential exploitation signs and maintaining secure network practices.
Description
A security issue exists in the protected mode of 1756-EN4TR and 1756-EN2TR communication modules, where a Concurrent Forward Close operation can trigger a Major Non-Recoverable (MNFR) fault. This condition may lead to unexpected system crashes and loss of device availability.
