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 | 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 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:
|
Documentation | Provides a link to the release notes for
the corresponding version. |
| Remove the previously downloaded content
release version from the firewall. |
Upload | 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, Upload the
update to the firewall. You then select Install From
File and select the file you downloaded. |
Install From File | After you manually upload an update file
to the firewall, use this option to install the file. In the Package Type drop-down,
select the type of update you are installing (Application
and Threats, Antivirus, or WildFire),
click OK, select the file you want to install
and then click OK again to start the installation. |
