Cisco Firepower (Sourcefire IDS, Cisco FireSIGHT)

Previously known as Sourcefire 3D, Cisco Firepower is an intrusion detection response system that produces security data and enhances the InsightIDR analysis. You can also send Web Proxy events from Cisco Firepower. InsightIDR automatically separates and parses your IDS and Web proxy logs from this application.

Configuration Instructions work for Cisco Firepower, Sourcefire 3D, and Cisco FireSIGHT

The configuration instructions in this document work for Cisco Firepower, Sourcefire 3D, and Cisco FireSIGHT. Even if you have Cisco Firepower or Cisco FireSIGHT, you still must select Sourcefire 3D in the Event Source dropdown list when configuring in InsightIDR.

Configure Sourcefire 3D, Cisco Firepower, or Cisco FireSIGHT to Send Alerts to InsightIDR

  1. Go to the SourceFire admin panel.
  2. Select Policies > Actions > Alerts. A pop-up window appears.
  3. From the Create Alert drop-down menu, select Create Syslog Alert. A dialog box appears.
  4. In the Name field, type the name you want to use to identify the saved response.
  5. In the Host field, type the hostname or IP address of your syslog server.
    • Note that the system does not warn you if you enter an invalid IPv4 address in this field (such as 192.168.1.456). Instead, the invalid address is treated as a hostname.
  6. In the Port field, enter the port that you will configure your InsightIDR collector to use for this event source.
    • By default, this value is 514.
  7. Select ALERT for facility.
  8. Select ALERT severity.
  9. In the Tag field, type the tag name that you want to appear with the syslog message. Use only alphanumeric characters in tag names. You cannot use spaces or underscores.
  10. Click Save.

When you create an alert response, it is automatically enabled. Only enabled alert responses can generate alerts. To stop alerts from being generated, you can temporarily disable alert responses rather than deleting your configurations.

Configure InsightIDR to collect data from the event source

After you complete the prerequisite steps and configure the event source to send data, you must add the event source in InsightIDR.

To configure the new event source in InsightIDR:

  1. From the left menu, go to Data Collection and click Setup Event Source > Add Event Source.
  2. Do one of the following:
    • Search for Cisco Firepower in the event sources search bar.
    • In the Product Type filter, select IDS.
  3. Select the Cisco Firepower event source tile.
  4. Choose your collector.
  5. In the Select Event Source Type field, choose the option that corresponds to your Cisco Security Solution as outlined in the following table:
Cisco Security SolutionInsightIDR Event Source Type
ASACisco ASA event-source
NGIPSCisco ASA event-source
NGFWCisco ASA event-source
Any other firepower serviceCisco ASA event-source
Cisco ASA with FirePower servicesCisco ASA event-source
Cisco FirePower Threat Defense (FTD)Cisco FTD event-source
Sourcefire 3DCisco FirePower (Sourcefire 3D) event-source

You can also name your event source if you want.

  1. Choose the timezone that matches the location of your event source logs.
  2. Optionally choose to send unparsed logs.
  3. Select an attribution source.
  4. Select Listen on Network Port and specify the port you used earlier along with a protocol.
    • Optionally choose to Encrypt the event source if choosing TCP by downloading the Rapid7 Certificate.
  5. Click Save.

Verify the Configuration

To see Cisco Firepower logs in InsightIDR: From the left menu, click Log Search to view your logs to ensure events are being forwarded to the Collector. Select the applicable Log Sets and the Log Names within them. The Log Name will be the event source name or “Cisco Firepower” if you did not name the event source. Cisco Firepower logs flow into these Log Sets:

  • Web Proxy
  • Intrusion Detection System (IDS)

Logs take a minimum of 7 minutes to appear in Log Search

Please note that logs take at least 7 minutes to appear in Log Search after you set up the event source.
