A customer’s Palo Alto Networks NGFW currently has only one security policy allowing all traffic. They have identified that this is a substantial security risk and have heard that the Expedition tool can help them extract security policies from an “allow any” rule. What should the consultant say about Expedition?

By using the Machine Learning feature, Expedition can parse the traffic log files related to the policy and extract security rules for matching traffic.

The log flies can be viewed on Expedition, and right-clicking a log entry gives the option to create security policy from the log entry.

Expedition cannot parse log files and therefore cannot be used for this purpose.

Live firewall traffic can be viewed on Expedition when connected to a firewall, and Expedition can automatically create and push policies to the firewall.
