[Deprecated] Nozomi Networks N2OS via Legacy Agent connector for Microsoft Sentinel
Important
Log collection from many appliances and devices is now supported by the Common Event Format (CEF) via AMA, Syslog via AMA, or Custom Logs via AMA data connector in Microsoft Sentinel. For more information, see Find your Microsoft Sentinel data connector.
The Nozomi Networks data connector provides the capability to ingest Nozomi Networks Events into Microsoft Sentinel. Refer to the Nozomi Networks PDF documentation for more information.

Note
This data connector depends on a parser based on a Kusto Function to work as expected NozomiNetworksEvents which is deployed with the Microsoft Sentinel Solution.
- Linux Syslog agent configuration
Install and configure the Linux agent to collect your Common Event Format (CEF) Syslog messages and forward them to Microsoft Sentinel.
Notice that the data from all regions will be stored in the selected workspace
1.1 Select or create a Linux machine
Select or create a Linux machine that Microsoft Sentinel will use as the proxy between your security solution and Microsoft Sentinel this machine can be on your on-prem environment, Azure or other clouds.
1.2 Install the CEF collector on the Linux machine
Install the Microsoft Monitoring Agent on your Linux machine and configure the machine to listen on the necessary port and forward messages to your Microsoft Sentinel workspace. The CEF collector collects CEF messages on port 514 TCP.
- Make sure that you have Python on your machine using the following command: python -version.
- You must have elevated permissions (sudo) on your machine.
Run the following command to install and apply the CEF collector:
sudo wget -O cef_installer.py https://raw.githubusercontent.com/Azure/Azure-Sentinel/master/DataConnectors/CEF/cef_installer.py&&sudo python cef_installer.py {0} {1}
- Forward Common Event Format (CEF) logs to Syslog agent
Follow these steps to configure Nozomi Networks device for sending Alerts, Audit Logs, Health Logs log via syslog in CEF format:
- Log in to the Guardian console.
- Navigate to Administration->Data Integration, press +Add and select the Common Event Format (CEF) from the drop down
- Create New Endpoint using the appropriate host information and enable Alerts, Audit Logs, Health Logs for sending.
- Validate connection
Follow the instructions to validate your connectivity:
Open Log Analytics to check if the logs are received using the CommonSecurityLog schema.
It may take about 20 minutes until the connection streams data to your workspace.
If the logs are not received, run the following connectivity validation script:
- Make sure that you have Python on your machine using the following command: python -version
- You must have elevated permissions (sudo) on your machine
Run the following command to validate your connectivity:
sudo wget -O cef_troubleshoot.py https://raw.githubusercontent.com/Azure/Azure-Sentinel/master/DataConnectors/CEF/cef_troubleshoot.py&&sudo python cef_troubleshoot.py {0}
- Secure your machine
Make sure to configure the machine's security according to your organization's security policy
