The types of data that Enhanced Application logs gather include records of DNS
queries, the HTTP header User Agent field that specifies the web browser or tool
used to access a URL, and information about DHCP automatic IP address
assignment. With DHCP information, for example,
Cortex XDR™ can alert on unusual
activity based on hostname instead of IP address. This allows the security
analyst using Cortex XDR to meaningfully assess whether the user’s activity is
within the scope of their role, and if not, to more quickly take action to stop
the activity.
To benefit from the most comprehensive set of Enhanced Application logs, enable
User-ID; deployments for the Windows-based User-ID agent and the PAN-OS
integrated User-ID agent both collect some data that is not reflected in the
NGFW User-ID logs but that is useful toward associating network activity with
specific users.
To start forwarding Enhanced Application logs to the Strata Logging Service, turn on Enhanced Application Logging (EAL) globally, and then enable it on a
per-security rule basis (using a Log Forwarding profile). The global setting is
required and captures data for traffic that is not session-based (ARP requests,
for example). The per-security policy rule setting is strongly recommended; the
majority of Enhanced Application logs are gathered from the session-based
traffic that your Security policy rules enforce.
