[Deprecated] Cisco Meraki connector for Microsoft Sentinel

Article
08/22/2024

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 Cisco Meraki connector allows you to easily connect your Cisco Meraki (MX/MR/MS) logs with Microsoft Sentinel. This gives you more insight into your organization's network and improves your security operation capabilities.

Prerequisites

To integrate with [Deprecated] Cisco Meraki make sure you have:

Cisco Meraki: must be configured to export logs via Syslog

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 CiscoMeraki and load the function code or click here. The function usually takes 10-15 minutes to activate after solution installation/update.

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.

Configure the logs to be collected

Follow the configuration steps below to get Cisco Meraki device logs into Microsoft Sentinel. Refer to the Azure Monitor Documentation for more details on these steps. For Cisco Meraki logs, we have issues while parsing the data by OMS agent data using default settings. So we advice to capture the logs into custom table meraki_CL using below instructions.

Login to the server where you have installed OMS agent.
Download config file meraki.conf wget -v https://aka.ms/sentinel-ciscomerakioms-conf -O meraki.conf
Copy meraki.conf to the /etc/opt/microsoft/omsagent/workspace_id/conf/omsagent.d/ folder. cp meraki.conf /etc/opt/microsoft/omsagent/<<workspace_id>>/conf/omsagent.d/
Edit meraki.conf as follows:

a. meraki.conf uses the port 22033 by default. Ensure this port is not being used by any other source on your server

b. If you would like to change the default port for meraki.conf make sure that you dont use default Azure monitoring /log analytic agent ports I.e.(For example CEF uses TCP port 25226 or 25224)

c. replace workspace_id with real value of your Workspace ID (lines 14,15,16,19)
Save changes and restart the Azure Log Analytics agent for Linux service with the following command: sudo /opt/microsoft/omsagent/bin/service_control restart
Modify /etc/rsyslog.conf file - add below template preferably at the beginning / before directives section $template meraki,"%timestamp% %hostname% %msg%\n"
Create a custom conf file in /etc/rsyslog.d/ for example 10-meraki.conf and add following filter conditions.

With an added statement you will need to create a filter which will specify the logs coming from the Cisco Meraki to be forwarded to the custom table.

reference: Filter Conditions — rsyslog 8.18.0.master documentation

Here is an example of filtering that can be defined, this is not complete and will require additional testing for each installation. if $rawmsg contains "flows" then @@127.0.0.1:22033;meraki & stop if $rawmsg contains "firewall" then @@127.0.0.1:22033;meraki & stop if $rawmsg contains "urls" then @@127.0.0.1:22033;meraki & stop if $rawmsg contains "ids-alerts" then @@127.0.0.1:22033;meraki & stop if $rawmsg contains "events" then @@127.0.0.1:22033;meraki & stop if $rawmsg contains "ip_flow_start" then @@127.0.0.1:22033;meraki & stop if $rawmsg contains "ip_flow_end" then @@127.0.0.1:22033;meraki & stop
Restart rsyslog systemctl restart rsyslog
Configure and connect the Cisco Meraki device(s)

Follow these instructions to configure the Cisco Meraki device(s) to forward syslog. Use the IP address or hostname for the Linux device with the Linux agent installed as the Destination IP address.
