Azure Sentinel: The connectors grand (CEF, Syslog, Direct, Agent, Custom and more)

(Last updated Apr 20th, 2021)

Please note that as the built-in list of connectors in Azure Sentinel is growing, this list is not actively maintained anymore. Refer to the Azure Sentinel connector documentation for more information.

Source types

Built-in

Built-in connectors are included in the Azure Sentinel documentation and the data connectors pane in the product itself. Those connectors are based on one of the technologies listed below. Therefore a built-in connector will have a type: CEF, Syslog, Direct, and so forth.

Syslog and CEF

Most network and security systems support either Syslog or CEF (which stands for Common Event Format) over Syslog as means for sending data to a SIEM. This makes Syslog or CEF the most straightforward ways to stream security and networking events to Azure Sentinel.

Want to learn more about best practices for CEF collection? see here.
Want to scale CEF or Syslog collection? Use a VM scale set as described here.

The advantage of CEF over Syslog is that it ensures the data is normalized, making it more immediately useful for analysis using Sentinel. However, unlike many other SIEM products, Sentinel allows ingesting unparsed Syslog events and performing analytics on them using query time parsing.

The number of systems supporting Syslog or CEF is in the hundreds, making the table below by no means comprehensive. We will update this list continuously. The table provides links to the source device's vendor documentation for configuring the device to send events in Syslog or CEF.

Tip: Want to ingest test CEF data? here is how to do that.

Direct

Most Microsoft cloud sources and many other clouds and on-prem systems can send to Azure Sentinel natively. For Microsoft Azure sources, this often uses their diagnostics feature, on which you can read more here.

Agent

The Log Analytics agent can collect different types of events from servers and endpoints listed here. To learn more about the agent, read Azure Sentinel Agent: Collecting telemetry from on-prem and IaaS server.

Threat Intelligence (TI)

You can use one of the threat intelligence connectors:

Platform, which uses the Graph Security API
TAXII, which uses the TAXII 2.0 protocol

to ingest threat intelligence indicators, which are used by Azure Sentinel's built-in TI analytics rules, and to build your own rules. You can read more about the Threat Intelligence connectors in module #6 of the Azure Sentinel Ninja Training

Custom: Logic Apps, Logstash, Azure Functions, and others

In addition to CEF and Syslog, many solutions are based on Sentinel's data collector API and create custom log tables in the workspace. Those belong to 3 groups:

Sources that support Logstash, which in turn has an output plug-in that can send the events to Azure Sentinel.
Sources that have native support for the API.
Sources for which there is a community or Microsoft field created solution that uses the API, usually using Logic Apps or an Azure function.

You can read more about custom connectors here.

Automation and integration

While all the types above focused on getting telemetry into Azure Sentinel, connectors marked as automation/integration enable Azure Sentinel to implement other use cases such as sending information to another system or performing an action on another system. Those might be API-based on integration or Logic App-based integrations.

Is Azure sentinel planning on Normalising ingested logs? Other players in this space are normalising ingested logs (see Elastic Common Schema) and CEF being a legacy example. Is the Azure Sentinel Team planning on defining a normalised data model for ingested Azure and legacy logs ? This would make querying data sets a lot simpler.

At the moment logs are disparately sprayed across different log Analytics workspaces tables (this might be the wrong name):
SignInLogs -- AAD logs
AzureDiagnostics - SQL PaaS logs
SecurityEvent - Windows server logs - Split across windows and
Unix VM logs - Syslog

Otherwise if MS team can provide some guidance per Azure service and where the logs are recorded and how you can link or query across these unique Log Analytics tables?

Thanks in advance for your assistance.

Jwcoxy1973, I had the same problem. In my case, with rsyslog, the problem was in the /etc/rsyslog.conf file. That is the general configuration file of rsyslog and by default it has the TCP and UDP syslog reception commented in the Modules section of the file. If you uncomment the one you need or both, and restart the rsyslog service, then you should receive the logs in Sentinel after a couple of minutes. You can also comment there the reception of syslog from the local machine, that way you will only have in sentinel the logs from netscaler in your case.
About the custom logs, I can't help you as I am having some issues of my own about that.

Chi_Duong : Yes, but it would require direct edit to the agent and syslog daemon configuration files.

Update (Dec 26th 2019): You no longer need to directly edit the configuration files:

Install the CEF connector VM using the instructions in the connector page.

Configure the facilities & priorities that you want to get Syslog messages of using Settings -> Workspace Settings -> Advanced Settings -> Data -> Syslog

Make sure that the facility/priority combination used by your CEF source is not configured for Syslog collection

That’s it. If #3 is not doable, we will have to revert to config file editing on the VM.

majo1 :

First to your specific challenge: since the events are Syslog, they require setting up the Syslog connector rather than, or in addition to, the CEF connector. As things are now, the Syslog messages are rejected.

To have a single connector VM support both CEF and Syslog:

Install the CEF connector VM using the instructions in the connector page (the new procedure in case yours was setup before October).

Configure the facilities & priorities that you want to get Syslog messages of using Settings -> Workspace Settings -> Advanced Settings -> Data -> Syslog

Make sure that the facility/priority combination used by your CEF source is not configured for Syslog collection

That’s it. If #3 is not doable, we will have to revert to config file editing on the VM.

As to your question:

You will need custom parsers as described in the custom connector blog post.

A troubleshooting script is available for CEF. For Syslog I suggest working with support.

Having a connector listed in the connector page implies parsing, however most of them are CEF, which means parsed as sent. This does not hold true for the list here.

Ofer_Shezaf going back to the dual CEF/Syslog server. How should the configuration files look? (assuming rsyslog)
security-config-omsagent.conf - should they have both entries for syslog / cef?

:rawmsg, regex, "CEF\|ASA" ~
