Configure Inline Cloud Analysis (PAN-OS & Panorama)

Advanced Threat Prevention Inline Cloud Analysis supports multiple detection engines, which require different minimum PAN-OS releases to enable:

Detection of advanced C2 (command-and-control) and spyware threats requires PAN-OS 10.2 and later.
Detection of zero-day exploit threats requires PAN-OS 11.0 and later.
Support for LDL (Local Deep Learning) requires PAN-OS 11.2 and later.

Log in to the PAN-OS web interface.
To take advantage of inline cloud analysis, you must have an active Advanced Threat Prevention subscription.
To verify subscriptions for which you have currently-active licenses, select DeviceLicenses 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 (to analyze traffic for advanced C2 (command-and-control) and spyware threats in real-time).
1. Select an existing Anti-Spyware Profile or Add a new one (ObjectsSecurity ProfilesAnti-Spyware).
2. Select your Anti-Spyware profile and then go to Inline Cloud Analysis and Enable inline cloud analysis.
3. (Local Deep Learning [Supported in PAN-OS 11.2 and later]) Select enable for each available analysis engine with a Local Deep Learning (LDL) option. There are currently two analysis engines available with an optional LDL mode: HTTP Command and Control detector and HTTP2 Command and Control detector.
4. Specify an Action to take when a threat is detected using a corresponding analysis engine.
  
  The default action for each analysis engine is alert, however, Palo Alto Networks recommends setting all actions to Reset-Both for the best security posture.
  - 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.
5. Click OK to exit the Anti-Spyware Profile configuration dialog and Commit your changes.
(Optional) Add URL and/or IP address exceptions to your Anti-Spyware profile if Inline Cloud Analysis produces false-positives. You can add exceptions by specifying an external dynamic list (URL or IP address list types) or an Addresses object.
1. Add an External Dynamic Lists or [IP] Addresses object exception.
2. Select Objects > Security Profiles > Anti-Spyware.
3. Select an Anti-Spyware profile for which you want to exclude specific URLs and/or IP addresses and then select Inline Cloud Analysis.
4. Add an EDL URL or IP Address, depending on the type of exception you want to add, and then select a pre-existing URL or IP address external dynamic list. If none are available, create a new external dynamic list. For IP address exceptions, you can, optionally, select an Addresses object list.
  
  Anti-spyware profiles that are configured as Shared on Panorama-managed firewalls cannot have IP address objects added to the Inline Cloud Analysis exceptions list.
5. Click OK to save the Anti-Spyware profile and Commit your changes.
(Supported in PAN-OS 11.0 and later) Update or create a new Vulnerability Protection Security profile to enable inline cloud analysis (to analyze traffic for command injection and SQL injection vulnerabilities in real-time).
1. Select an existing Vulnerability Protection security profile or Add a new one (ObjectsSecurity ProfilesVulnerability Protection).
2. Select your Vulnerability Protection profile and then go to Inline Cloud Analysis and Enable cloud inline analysis.
3. Specify an Action to take when a vulnerability exploit is detected using a corresponding analysis engine. There are currently two analysis engines available: SQL Injection and Command Injection.
  - Allow—The request is allowed and no log entry is generated.
  - Alert—The request is allowed and a Threat log entry is generated.
  - 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.
4. Click OK to exit the Vulnerability Protection Profile configuration dialog and Commit your changes.
(Optional) Add URL and/or IP address exceptions to your Vulnerability Protection profile if Inline Cloud Analysis produces false-positives. You can add exceptions by specifying an external dynamic list (URL or IP address list types) or an Addresses object.
1. Add an External Dynamic Lists or [IP] Addresses object exception.
2. Select Objects > Security Profiles > Vulnerability to return to your Vulnerability Protection profile.
3. Select a Vulnerability profile for which you want to exclude specific URLs and/or IP addresses and then select Inline Cloud Analysis.
4. Add an EDL URL or IP Address, depending on the type of exception you want to add, and then select a pre-existing URL or IP address external dynamic list. If none are available, create a new external dynamic list. For IP address exceptions, you can, optionally, select an Addresses object list.
  
  Vulnerability profiles that are configured as Shared on Panorama-managed firewalls cannot have IP address objects added to the Inline Cloud Analysis exceptions list.
5. Click OK to save the Vulnerability Protection profile and Commit your changes.
Configure the timeout latency and action to take when the request exceeds the max latency.
1. Select DeviceSetupContent-IDThreat Prevention Inline Cloud Analysis.
2. Specify the timeout value and the associated action to take when latency limits are reached for Inline Cloud Analysis requests:
  - Max Latency (ms)—Specify the maximum acceptable processing time, in seconds, for Inline Cloud Analysis to return a result.
  - Allow on Max Latency—Enables the firewall to take the action of allow, when the maximum latency is reached. De-selecting this option sets the firewall action to block.
  - Log Traffic Not Scanned— Enables the firewall to log traffic requests that exhibit anomalous traits indicating the presence of advanced and evasive command-and-control (C2) threats, but have not been processed by Threat Prevention Inline Cloud analyzers.
3. Click OK to confirm your changes.
Install a Device Certificate Repeat for all firewalls enabled for inline cloud analysis.
(Required when the firewall is deployed with an explicit proxy server) Configure the proxy server used to access the servers that facilitate requests generated by all configured inline cloud analysis features. A single proxy server can be specified and applies to all Palo Alto Networks update services, including all configured inline cloud and logging services.
1. (PAN-OS 11.2.3 and later) Configure the proxy server through PAN-OS.
  Select Device Setup Services and edit the Services details.
  Specify the Proxy Server settings and Enable proxy for Inline Cloud Services. You can provide either an IP address or FQDN in the Server field.
  
  The proxy server password must contain a minimum of six characters.
  
  Click OK.
2. (For the following releases only: PAN-OS 10.2.11 and later and PAN-OS 11.1.5 and later) Configure the proxy server through the firewall CLI.
  Access the firewall CLI.
  Configure the base proxy server settings using the following CLI commands:
  set deviceconfig system secure-proxy-server <FQDN_or_IP> set deviceconfig system secure-proxy-port <1-65535> set deviceconfig system secure-proxy-user <value> set deviceconfig system secure-proxy-password <value>
  
  The proxy server password must contain a minimum of six characters.
  
  Enable the proxy server to send requests to the inline cloud service servers using the following CLI command:
  debug dataplane mica set inline-cloud-proxy enable
  View the current operational status of proxy support for inline cloud services using the following CLI command:
  debug dataplane mica show inline-cloud-proxy
  
  For example:
  debug dataplane mica show inline-cloud-proxy Proxy for Advanced Services is Disabled
(Optional) Set the Cloud Content Fully Qualified Domain Name (FQDN) used by the firewall to handle inline cloud analysis service requests. The default FQDN connects to hawkeye.services-edge.paloaltonetworks.com and then resolves to the closest cloud services server. You can override the automatic server selection by specifying a regional cloud content server that best meets your data residency and performance requirements.

The Cloud Content FQDN is a globally used resource and affects how other services that rely on this connection sends traffic payloads.
Verify that the firewall uses the correct Content Cloud FQDN (DeviceSetupContent-IDContent Cloud Setting) for your region and change the FQDN if necessary:

If your NGFW is configured inline to facilitate a SaaS Security deployment, please note that the FQDNs located in France and Japan do not currently support SaaS Security functionality.
