A manufacturing company utilizes an integrated system to monitor and control their factory operations. Recently, they have been concerned about potential cybersecurity threats that could disrupt production. As part of enhancing their network security, which of the following actions would be MOST effective in protecting their operational systems?
Regularly update all computer and network devices with the latest software patches.
Secure wireless signals by switching to WEP security protocol for all connections.
Implement network segmentation to isolate the critical industrial systems from the corporate IT network.
Change default passwords on all network connected devices within the factory.
Implementing network segmentation isolates critical industrial systems from the corporate IT network, significantly reducing the risk of unauthorized access or malware spreading from less secure networks. Although changing default passwords and securing wireless signals are important security measures, they do not directly address the heightened risks associated with interconnected industrial environments. Regular software updates are crucial but would not be the sole or most effective strategy for securing industrial control systems where system stability and compatibility are critical, and updates must be carefully managed.
