In addition to CEF and Syslog, many solutions are based on Sentinel's data collector API and create custom log tables in the workspace. You can read more about the Threat Intelligence connectors in module #6 of the Azure Sentinel Ninja TrainingĬustom: Logic Apps, Logstash, Azure Functions, and others To ingest threat intelligence indicators, which are used by Azure Sentinel's built-in TI analytics rules, and to build your own rules. TAXII, which uses the TAXII 2.0 protocol.Platform, which uses the Graph Security API.You can use one of the threat intelligence connectors: To learn more about the agent, read Azure Sentinel Agent: Collecting telemetry from on-prem and IaaS server. The Log Analytics agent can collect different types of events from servers and endpoints listed here. For Microsoft Azure sources, this often uses their diagnostics feature, on which you can read more here. Most Microsoft cloud sources and many other clouds and on-prem systems can send to Azure Sentinel natively.

Tip: Want to ingest test CEF data? here is how to do that. The table provides links to the source device's vendor documentation for configuring the device to send events in Syslog or CEF. The number of systems supporting Syslog or CEF is in the hundreds, making the table below by no means comprehensive. However, unlike many other SIEM products, Sentinel allows ingesting unparsed Syslog events and performing analytics on them using query time parsing. The advantage of CEF over Syslog is that it ensures the data is normalized, making it more immediately useful for analysis using Sentinel. Want to scale CEF or Syslog collection? Use a VM scale set as described here.Want to learn more about best practices for CEF collection? see here.This makes Syslog or CEF the most straightforward ways to stream security and networking events to Azure Sentinel. 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. Therefore a built-in connector will have a type: CEF, Syslog, Direct, and so forth. Those connectors are based on one of the technologies listed below. Refer to the Azure Sentinel connector documentation for more information.īuilt-in connectors are included in the Azure Sentinel documentation and the data connectors pane in the product itself. In the Log Settings section, set IPFIX Streaming to yes.Please note that as the built-in list of connectors in Azure Sentinel is growing, this list is not actively maintained anymore.From the Configuration Mode menu, select Switch to Advanced View.

(optional) Enable IPFIX for the HTTP Proxy Service If you are using TCP/TLS, configure the TLS certificate settings.Select the protocol from the Export Mode list. UDP is supported by most collectors.Enter a Name for the collector settings and click OK.Click + next to Collectors to add an IPFIX collector.Custom - Select this option to define a custom template by selecting the individual Information Elements that should be sent.Extended without proprietary fields - This template contains all data of the extended template, but omits all Barracuda proprietary fields.Extended - This template extends the default template with the elements octetTotalCount, packetTotalCount and timestamps relative to the system uptime.

Default - This is the default template and includes all data from the basic templates plus all Barracuda proprietary fields.

Basic – Includes only the most basic data and should therefore be compatible with most collectors.

(optional) Enter the Intermediate Reporting Interval for intermediate reports in minutes.

(optional) Set Enable Intermediate Flow Report to yes.

In the IPFIX Streaming section, set Enable IPFIX Export to yes.

In the left menu, select Audit and Reporting.

Go to CONFIGURATION > Configuration Tree > Box > Infrastructure Services > General Firewall Configuration.

Enable and Configure IPFIXīefore you can export network flow information, you must enable and configure IPFIX. For exporting network flow information with IPFIX, complete the following steps: Step 1.
