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 Sophos XG Firewall and load the function code or click here, on the second line of the query, enter the hostname(s) of your Sophos XG Firewall device(s) and any other unique identifiers for the logstream. The function usually takes 10-15 minutes to activate after solution installation/update.

  1. Install and onboard the agent for Linux

Typically, you should install the agent on a different computer from the one on which the logs are generated.

Syslog logs are collected only from Linux agents.

  1. Configure the logs to be collected

Configure the facilities you want to collect and their severities.

  1. Under workspace advanced settings Configuration, select Data and then Syslog.

  2. Select Apply below configuration to my machines and select the facilities and severities.

  3. Click Save.

  4. Configure and connect the Sophos XG Firewall

Follow these instructions to enable syslog streaming. Use the IP address or hostname for the Linux device with the Linux agent installed as the Destination IP address.
