How do businesses assess risks tied to rogue IoT gateways in operational technology (OT) networks?

Businesses evaluate vulnerabilities tied to rogue IoT gateways in OT networks by implementing thorough security measures such as:

1. Conducting regular network assessments to identify potential vulnerabilities.
2. Implementing strong access controls and authentication mechanisms to prevent unauthorized access to IoT gateways.
3. Updating IoT gateway software and firmware to patch known vulnerabilities.
4. Utilizing intrusion detection systems to monitor network traffic for any suspicious activities.
5. Employing encryption techniques to secure communication between devices and the gateway.
6. Establishing network segmentation to contain potential threats and limit their impact.
7. Training employees on proper security protocols and best practices to reduce the risk of human error leading to vulnerabilities.

By following these measures, businesses can effectively evaluate and mitigate vulnerabilities associated with rogue IoT gateways in OT networks.
