PANW-IP-000008 - The Palo Alto Networks security platform must capture traffic of detected/dropped malicious code.

Information

Associating event outcome with detected events in the log provides a means of investigating an attack or suspected attack.

The logs should identify what servers, destination addresses, applications, or databases were potentially attacked by logging communications traffic between the target and the attacker. All commands that were entered by the attacker (such as account creations, changes in permissions, files accessed, etc.) during the session should also be logged when capturing for forensic analysis.

Packet captures of attack traffic can be used by forensic tools for analysis for example, to determine if an alert is real or a false alarm or for forensics for threat intelligence. Configure the packet capture filters so that the CPU is not overloaded. There are many reasons for a packet capture. This requirement addresses the case where the capture is based on forensics for a detected malicious attack and the traffic is being captured in association with that traffic. Filtering should be engaged to facilitate forensics.

Solution

This procedure will only capture the first packet. See the vendor documentation for further information.
