The best way to view a complete overview of the logs is to select the unified log entry in the side menu. The unified log is a single view that displays all the logs generated by the firewall, such as traffic, threat, URL filtering, data filtering, and WildFire logs1. The unified log allows the administrator to filter, sort, and export the logs based on various criteria, such as time range, severity, source, destination, application, or action1.

Modifying the number of columns visible on the page or the number of logs visible on each page does not provide a complete overview of the logs, but only changes the display settings of the current log view. Selecting the system logs entry in the side menu does not show all the logs generated by the firewall, but only shows the logs related to system events, such as configuration changes, system alerts, or HA status2.

Palo Alto Networks firewalls can map IP addresses to usernames using various methods, such as User-ID agents, Captive Portal, GlobalProtect, XML API, and HTTP headers. These methods allow the firewall to enforce security policies based on user identity, rather than just IP address. Some of these methods are:

• Using the XML API: The XML API allows external systems to send user mapping information to the firewall using HTTPS requests. The firewall can then use this information to identify the users behind the IP addresses and apply the appropriate policies1.
• A user connecting into a GlobalProtect gateway using a GlobalProtect Agent: GlobalProtect provides secure remote access to the network by establishing a VPN tunnel between the user’s device and the firewall. When a user connects to a GlobalProtect gateway using a GlobalProtect agent, the firewall can authenticate the user and map the user’s IP address to the username1.
• Usernames inserted inside HTTP Headers: The firewall can also extract usernames from HTTP headers in web traffic. This method requires the web server or proxy server to insert the username into a custom HTTP header that the firewall can read. The firewall can then use this information to map the IP address to the username1.
