Cisco ASA via SIEM Setup for Workbench

This procedure helps you to connect your Cisco ASA via SIEM to the Expel Workbench. The procedure is to port in logs by creating a new Syslog source, configuring that source in Workbench, then your Cisco ASA through SIEM device in Workbench.

Note
Some steps in this procedure vary greatly depending upon the SIEM-based technology you use.

Quick Start

Step 1: Logging Cisco ASA to a desired SIEM

Refer to your SIEM documentation or work with your SIEM representative to port in Cisco ASA logs. You can also refer to the following web references for creating a new Syslog source:

Step 2: Configure the SIEM in Workbench

This link opens the Expel Knowledge Base section for connecting SIEM-based technology to Workbench. Follow the applicable article to configure your SIEM-based tech and confirm that Cisco ASA logs are flowing through and available.

Step 3: Configure Cisco ASA via SIEM in Workbench

Now that we have the correct access configured and noted the credentials, we can integrate your tech with Workbench.

Note
Expel secures all login information our SOC analysts need about your devices in an MFA password product. Access to this login information is protected using our internal MFA processes. To learn more about the IP addresses all Expel traffic comes from, go here.

    Add Cisco ASA via SIEM security device

  2. Fill in the device fields like this:

    • For SIEM, select the SIEM that was onboarded in Step 2.

    • For Name, type the host name of the Cisco ASA device.

    • For Location, type the geographic location of the device.

  3. Fill in the Connection Settings fields based on the SIEM you selected:

    • For Source type, type the Splunk source type for this device.

    • For Source category, type the Sumo Logic source category for this device.

    • For Index, type in the Splunk index where the logs are located. By default this is filled in with a wildcard (*).

  4. Click Save.

You can see if the device is healthy on the Security Devices page. It may take a few minutes to see the device listed as healthy.

To check if alerts are coming through, navigate to the Alerts Analysis page. Scroll to the device you want to check and click View alerts. Switch to grid view, then check the list for device alerts. It can take 36 to 72 hours for alerts to appear after setup, as we tune your device.
