How to send Cowrie output to Azure Sentinel
Open your Sentinel worksapce and navigate to Data connectors > Syslog > Open connector page. Expand Install agent on a non-Azure Linux Machine, the select Download & install agent for non-Azure Linux machines. Select the Linux tab and either copy the shell script that is presented, or take note of your Workspace ID and Primary Key and install the agent on your host by hand:
$ wget https://raw.githubusercontent.com/Microsoft/OMS-Agent-for-Linux/master/installer/scripts/onboard_agent.sh $ chmod +x onboard_agent.sh $ ./onboard_agent.sh -w <workspace ID> -s <key> -d opinsights.azure.com
Once installed, return to the Syslog connector page and select Open
your workspace advanced settings configuration. Select Data >
Custom Logs. Check Apply below configuration to my linux machines
then add a new custom log source: When prompted, upload the
file you downloaded.
The default delimeter is correct (newline). Specify
/opt/cowrie/var/log/cowrie/cowrie.json as the log collection path.
Name the custom log
cowrie_JSON. Sentinel will automatically
append _CL to this name.
It will take a while for this to roll out to the host, but eventually you’ll be able to run the log analytics query cowrie_JSON_CL and see data coming in.
Take the contents of
cowrie-parser.txt from the
and paste them into a new log analytics query. Run the query,
then save this off as a function with the name, alias and category
Once events are being ingested and parsed by Azure Sentinel,
linux_workbook.json can be imported to define a custom workbook to
interact with Cowrie data.
