Palo Alto Networks regularly posts updates that include new and modified applications, threat protection, and GlobalProtect data files through dynamic updates. The firewall can retrieve these updates and use them to enforce policy, without requiring configuration changes. Application and some antivirus updates are available without a subscription; other are tied to your subscriptions.
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
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.
Displays the date and time that the firewall last connected to the update server and checked if an update was available.
Allows you to schedule the frequency for retrieving updates.
You can define how often and when the dynamic content updates occur—the

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 WildFire updates, you have the option to retrieve signatures in real-time, allowing you to access the signatures as soon as they are generated. Signatures that are downloaded during a sample check are saved in the firewall cache, and are available for fast (local) look-ups. In addition, to maximize coverage, the firewall also automatically downloads an additional signature package on a regular basis when real-time signatures is enabled. These supplemental signatures are added to the firewall cache and remain available until they become stale and are refreshed or are overwritten by new signatures.

List the filename; it includes the content version information.
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 Applicationsdialog to
Enable/Disablenew 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).

Remove the previously downloaded content release version from the firewall.
If the firewall does not have access to the Palo Alto Networks Update Server, you can manually download dynamic updates from the Palo Alto Networks Support site in the Dynamic Updates section. After you download an update to your computer,
Uploadthe update to the firewall. You then select
