Maximizing Cloud Connectivity Visibility
Overview
Defender for IoT help you protect your operational technology (OT) network from cyber threats. By using network sensors to monitor your network, you gain real-time insight into your OT devices and are notified if suspicious or malicious events occur.
The Defender for IoT cloud management is designed to augment your on-premises processing power while providing a source of centralized management for global security teams, raising the bar for OT defense.
By connecting your OT sensors to the Azure portal, you can get:
Holistic Insights: The Defender for IoT Azure portal becomes your watchtower, offering full visibility of your entire OT network. Health and security metrics converge in one place.
Real-Time Empowerment: Updates and alerts arrive in real time for one place from all your sites around the world.
Learn more- connecting your sensor to the cloud.
Connecting your OT sensors to the cloud is not always straightforward. There are many factors that can affect the connectivity of your OT sensors, such as network configuration, proxy settings, DNS servers, or SSL certificates. If any of these factors are not configured correctly, your OT sensors may not be able to communicate with the cloud. This can result in missing or delayed alerts and cause reduced visibility and control over your OT network.
To help you troubleshoot OT sensor connectivity issues, we have introduced a new capability in version 23.1.3 of the OT sensor software. It allows you to check the status of your sensor’s connection to the cloud and identify any errors or issues that may prevent it from communicating with the cloud. Ultimately, you received detailed steps to resolve this issue.
This tool will help you-
Streamlining troubleshooting
Reducing resolution time
Enhancing identification of connectivity issues
In this blog post, we will show you how to use the Cloud connectivity troubleshooting tool which can help you identify the root cause and provide you with a step-by-step explanation to fix some common connectivity issues that you may encounter.
How to Troubleshoot Sensor Connectivity Issues?
As an IoT/ OT Security project manager working for a manufacturing company. You are responsible for maintaining the OT network security and ensuring that your OT sensors are connected to the cloud.
One day, you notice that one of your sensors is not sending any data to the cloud. On the Site and Sensor page, you see that the sensor has disconnected health status –
on the sensor’s Overview page –
As you wonder what is causing this connectivity issue, you contact the network team on site to investigate it. When it comes to finding a connectivity issue it’s complex and can take hours and days.
Here is how the Cloud connectivity troubleshooting tool can help you in this scenario:
Step 1- Access the Cloud connectivity troubleshooting page:
From the sensor’s Overview page, select the Troubleshoot link in the error at the top of the page
or
Select System settings > Sensor management > Health and troubleshooting > Cloud connectivity troubleshooting
Step 2- Identify the connectivity issue
The Cloud connectivity troubleshooting pane opens on the right. If the sensor isn’t connected, a description of the issue and any mitigation instructions are listed.
Step 3- Fix the connectivity issue
The connectivity tool provides you with recommendations on how to fix your connectivity issues.
In case you still can’t fix the connectivity issue, please submit a support ticket and include the log files so the support engineer team can assist you as quickly as possible.
