Advanced Threat Prevention: Inline Cloud Analysis
Palo Alto Networks now operates a series of
ML-based detection engines in the Advanced Threat Prevention cloud
to analyze traffic for advanced C2 (command-and-control) and spyware
threats in real-time to protect users against zero-day threats.
By operating cloud-based detection engines, you can access a wide array
of detection mechanisms that are updated and deployed automatically
without requiring the user to download update packages or operate
process intensive, firewall-based analyzers which can sap resources.
The cloud-based detection engine logic is continuously monitored
and updated using C2 traffic datasets from WildFire, with additional
support through manual updates by Palo Alto Networks threat researchers,
who provide human intervention for highly accurized detection enhancements.
Inline cloud analysis supports five analysis engines for C2-based
threats over HTTP, HTTP2, SSL, unknown-UDP, and unknown-TCP. Additional
analysis models are delivered through content updates, however,
enhancements to existing models are performed as a cloud-side update,
requiring no firewall update. Inline cloud analysis is enabled and
configured using the anti-spyware profile and requires an active
Advanced Threat Prevention license.
- Log in to the PAN-OS web interface.
- To take advantage of inline categorization, you must
have an active Advanced Threat Prevention subscription.To verify subscriptions for which you have currently-active licenses, select and verify that the appropriate licenses are available and have not expired.

- Update or create a new Anti-Spyware Security profile
to enable inline cloud analysis.
- Select an existing Anti-Spyware Profile or Add a new one ().
- Select your Anti-Spyware profile and then go to Inline Cloud Analysis and Enable inline cloud analysis.

- Specify an Action to take when a threat is detected using a corresponding analysis engine. The following options are available:The default action for each analysis engine is alert.
- Allow—The request is allowed and no log entry is generated.
- Alert—The request is allowed and a Threat log entry is generated.
- Drop—Drops the request; a reset action is not sent to the host/application.
- Reset-Client—Resets the client-side connection.
- Reset-Server—Resets the server-side connection.
- Reset-Both—Resets the connection on both the client and server ends.
- Click OK to exit the Anti-Spyware Profile configuration dialog and Commit your changes.
- Install an updated firewall device certificate used to authenticate to the Advanced Threat Prevention inline cloud analysis service. Repeat for all firewalls enabled for inline cloud analysis.
