How can businesses improve threat visibility in OT networks?

Businesses can improve threat visibility in Operational Technology (OT) networks to identify and address potential risks by implementing the following strategies:

1. Asset Inventory: Develop a comprehensive inventory of all devices and equipment connected to the OT network to understand the scope of assets and potential vulnerabilities.

2. Network Segmentation: Implement network segmentation to isolate critical assets and limit the lateral movement of threats within the network.

3. Monitoring and Logging: Employ real-time monitoring and logging tools to track network activity and detect any anomalies or malicious behavior.

4. Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS): Deploy IDS and IPS to detect and prevent unauthorized access, malware infections, and other cyber threats.

5. Patch Management: Regularly update and patch OT devices, software, and systems to address known vulnerabilities and improve overall security posture.

6. Incident Response Plan: Develop a comprehensive incident response plan to effectively respond to security incidents and minimize their impact on OT operations.

7. Employee Training: Provide cybersecurity awareness training to OT staff to help them identify and respond to potential threats effectively.

8. External Security Assessment: Conduct regular security assessments and penetration testing with the help of third-party experts to identify vulnerabilities and enhance security controls.

By implementing these measures, businesses can enhance threat visibility in OT networks and proactively address potential risks to secure their critical infrastructure and operations.
