Vendor installation instructions

NOTE: This data connector depends on a parser based on a Kusto Function to work as expected which is deployed as part of the solution. To view the function code in Log Analytics, open Log Analytics/Microsoft Sentinel Logs blade, click Functions and search for the alias IllumioCoreEvent and load the function code or click here.The function usually takes 10-15 minutes to activate after solution installation/update and maps Illumio Core events to Microsoft Sentinel Information Model (ASIM).

  1. 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.

  1. Make sure that you have Python on your machine using the following command: python -version.
  1. 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}

  1. Configure Ilumio Core to send logs using CEF

2.1 Configure Event Format

  1. From the PCE web console menu, choose Settings > Event Settings to view your current settings.

  2. Click Edit to change the settings.

  3. Set Event Format to CEF.

  4. (Optional) Configure Event Severity and Retention Period.

2.2 Configure event forwarding to an external syslog server

  1. From the PCE web console menu, choose Settings > Event Settings.

  2. Click Add.

  3. Click Add Repository.

  4. Complete the Add Repository dialog.

  5. Click OK to save the event forwarding configuration.

  6. 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:

  1. Make sure that you have Python on your machine using the following command: python -version
  1. 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}

  1. Secure your machine

Make sure to configure the machine's security according to your organization's security policy
