Palo Alto Networks regularly posts updates for new and modified applications, threat protection, and GlobalProtect data files through dynamic updates as follows:
  • Antivirus—Includes new and updated antivirus signatures, including WildFire signatures and automatically-generated command-and-control (C2) signatures. WildFire signatures detect malware first seen by firewalls from around the world. Automatically-generated C2 signatures detect certain patterns in C2 traffic (instead of the C2 server sending malicious commands to a compromised system); these signatures enable the firewall to detect C2 activity even when the C2 host is unknown or changes rapidly. You must have a Threat Prevention subscription to get these updates. New antivirus signatures are published daily.
  • Applications—Includes new and updated application signatures. This update does not require any additional subscriptions, but it does require a valid maintenance/support contract. New application updates are published weekly.
  • Applications and Threats—Includes new and updated application and threat signatures. This update is available if you have a Threat Prevention subscription (in this case, you will get this update instead of the Applications update). New threat updates are published weekly, and application updates are published monthly. The firewall can retrieve the latest threat and application updates within as little as 30 minutes of availability.
    You also have the option to install new and modified applications on a delayed schedule. Configure new threat signatures to be installed more immediately so that the firewall is equipped with the latest threat protection, while staggering the threshold for application installation. This gives you extra time to assess and adjust your security policy based on the changes that new and modified applications introduce.
    For guidance on how to best enable application and threat updates to ensure both application availability and protection against the latest threats, review the Best Practices for Application and Threat Content Updates.
  • GlobalProtect Data File—Contains the vendor-specific information for defining and evaluating host information profile (HIP) data returned by GlobalProtect apps. You must have a GlobalProtect gateway subscription in order to receive these updates. In addition, you must create a schedule for these updates before GlobalProtect will function.
  • GlobalProtect Clientless VPN—Contains new and updated application signatures to enable Clientless VPN access to common web applications from the GlobalProtect portal. You must have a GlobalProtect subscription to receive these updates. In addition, you must create a schedule for these updates before GlobalProtect Clientless VPN will function.
  • BrightCloud URL Filtering—Provides updates to the BrightCloud URL Filtering database only. You must have a BrightCloud subscription to get these updates. New BrightCloud URL database updates are published daily. If you have a PAN-DB license, scheduled updates are not required as firewalls remain in-sync with the servers automatically.
  • WildFire—Provides near real-time malware and antivirus signatures created as a result of the analysis done by the WildFire public cloud. WildFire signature updates are made available every five minutes. You can set the firewall to check for new updates as frequently as every minute to ensure that the firewall retrieves the latest WildFire signatures within a minute of availability. Without the WildFire subscription, you must wait 24 to 48 hours for the WildFire signatures to roll into the Applications and Threat update. Select DeviceSetupWildFire to enable WildFire Public Cloud analysis.
  • WF-Private—Provides near real-time malware and antivirus signatures created as a result of the analysis done by a WildFire appliance. To receive content updates from a WildFire appliance, the firewall and appliance must both be running PAN-OS 6.1 or a later release and the firewall must be configured to forward files and email links to the WildFire Private Cloud. Select Device > Setup > WildFire to enable WildFire Private Cloud analysis.
You can view the latest updates, read the release notes for each update, and then select the update you want to download and install. You can also revert to a previously installed version of an update.
Setting a schedule for dynamic updates, allows you to define the frequency at which the firewall checks for and downloads or installs new updates. Particularly for Applications and Threats content updates, you might want to set a schedule that staggers new and modified application updates behind threat updates; this gives you more time to assess how new and modified applications impact your security policy, while ensuring that the firewall is always equipped with the latest threat protections.
Dynamic Updates Options
Description
Version
Lists the versions that are currently available on the Palo Alto Networks Update Server. To check if a new software release is available from Palo Alto Networks, click Check Now. The firewall uses the service route to connect to the Update Server and checks for new content release versions and, if there are updates available, displays them at the top of the list.
Last checked
Displays the date and time that the firewall last connected to the update server and checked if an update was available.
Schedule
Allows you to schedule the frequency for retrieving updates.
You can define how often and when the dynamic content updates occur—the Recurrence and time—and whether to Download Only or to Download and Install scheduled updates
For Antivirus and Applications and Threats updates, you have the option to set a minimum Threshold of time that a content update must be available before the firewall installs it. Very rarely, there can be an error in a content update and this threshold ensures that the firewall only downloads content releases that have been available and functioning in customer environments for the specified amount of time.
For Applications and Threats content updates, you can also set a threshold that applies specifically to content updates with new and modified applications. An extended application threshold gives you more time to assess and adjust your security policy based on changes that new or modified applications introduce.
For guidance on how to best enable Application and Threat content updates to achieve both constant application availability and the latest threat protection, review the Best Practices for Application and Threat Content Updates.
File Name
List the filename; it includes the content version information.
Features
Lists what type of signatures the content version might include.
For Applications and Threats content release versions, this field might display an option to review Apps, Threats. Click this option to view new application signatures made available since the last content release version installed on the firewall. You can also use the New Applications dialog to Enable/Disable new applications. You might choose to disable a new application included in a content release if you want to avoid any policy impact from an application being uniquely identified (an application might be treated differently before and after a content installation if a previously unknown application is identified and categorized differently).
Type
Indicates whether the download includes a full database update or an incremental update.
Size
Displays the size of the content update package.
Release Date
The date and time Palo Alto Networks made the content release available.
Downloaded
A check mark in this column indicates that the corresponding content release version has been downloaded to the firewall.
Currently Installed
A check mark in this column indicates that the corresponding content release version is currently running on the firewall.
Action
Indicates the current action you can take for the corresponding software image as follows:
  • Download—The corresponding content release version is available on the Palo Alto Networks Update Server; click to Download the content release version. If the firewall does not have access to the Internet, use an Internet-connected computer to go to the Customer Support Portal and select Dynamic Updates. Find the content release version you want and click Download to save the update package to your local computer. Then manually Upload the software image to the firewall. Additionally, downloading an Application and Threat content release version enables the option to Review Policies that are affected by new application signatures included with the release.
  • Review Policies (Application and Threat content only)—Review any policy impact for new applications included in a content release version. Use this option to assess the treatment an application receives both before and after installing a content update. You can also use the Policy Review dialog to add or remove a pending application (an application that is downloaded with a content release version but is not installed on the firewall) to or from an existing Security policy rule; policy changes for pending applications do not take effect until the corresponding content release version is installed.
  • Review Apps (Application and Threat content only)—View new and modified application signatures made available since the last content release version installed on the firewall. In cases where a content update introduces changes that might impact the enforcement of critical applications, those applications are marked as recommended for policy review. Click on Review Policies to see how content updates impact your existing security policy or, you can disable an application until you have time to review the application’s policy impact.
  • Install—The corresponding content release version has been downloaded to the firewall; click to Install the update. When installing a new Applications and Threats content release version, you are prompted with the option to Disable new apps in content update. This option enables protection against the latest threats, while giving you the flexibility to enable applications after preparing any policy updates, due to the impact of new application signatures (to enable applications you have previously disabled, select Apps, Threats on the Dynamic Updates page or select ObjectsApplications).
  • Revert—The corresponding content release version has been downloaded previously To reinstall the same version, click Revert.
