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 isn’t
reflected in the firewall User-ID logs but is useful for associating network
activity with specific users.
To start forwarding Enhanced Application
logs to Strata Logging Service, turn on Enhanced Application Logging
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 isn’t 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.
