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

Description
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.

Go to Objects >> Security Profiles >> Antivirus View the configured Antivirus Profiles. If the Packet Capture check box is not checked, this is a finding. Go to Objects >> Security Profiles >> Anti-Spyware View the configured Anti-Spyware Profiles. If the "Packet Capture" field does not show extended-capture, this is a finding. Go to Objects >> Security Profiles >> Vulnerability Protection View the configured Vulnerability Protection Profiles. If the "Packet Capture" field does not show extended-capture, this is a finding. Go to Policies >> Security Review each of the configured security policies in turn. For any Security Policy that affects traffic between Zones (interzone), view the "Profile" column. If the "Profile" column does not display the Antivirus Profile, Anti-Spyware, and Vulnerability Protection symbols, this is a finding.
