Ingest logs from Cisco ASA firewalls and AnyConnect - Administrator Guide - Cortex XDR - Cortex - Security Operations

If you use Cisco ASA firewalls or Cisco AnyConnect VPN, you can take advantage of Cortex XDR investigation and detection capabilities by forwarding your firewall and AnyConnect VPN logs to Cortex XDR. This enables Cortex XDR to examine your network traffic to detect anomalous behavior. Cortex XDR can use Cisco ASA firewall logs and AnyConnect VPN logs as the sole data source, but can also use Cisco ASA firewall logs in conjunction with Palo Alto Networks firewall logs. For additional endpoint context, you can also use Cortex XDR to collect and alert on endpoint data.

As soon as Cortex XDR starts to receive logs, the app can begin stitching network connection logs with other logs to form network stories. Cortex XDR can also analyze your logs to raise Analytics alerts and can apply IOC, BIOC, and Correlation Rules matching. You can also use queries to search your network connection logs using the Cisco Cortex Query Language (XQL) dataset (cisco_asa_raw).

To integrate your logs, you first need to set up an applet in a Broker VM within your network to act as a Syslog Collector. You then configure forwarding on your log devices to send logs to the Syslog Collector in a CISCO format.
