    It's a good idea to look at your external dynamic list (EDL) entries to assess the information present in these lists. Viewing external dynamic list entries gives you insights into the threat intelligence being used for Security policy enforcement, and helps you maintain an up to date and robust security posture.
    To access and view entries within an external dynamic list, navigate to the
    Objects
     tab and select
    External Dynamic Lists
    . Here, you can see a list of all configured external dynamic lists. Select a specific external dynamic list to view the entries it contains.
    External dynamic list entries typically comprise IP addresses, URLs, domain names, or other indicators of compromise, depending on the type of external dynamic list configured. Your configuration periodically fetches updates from the specified URL associated with the external dynamic list, ensuring that the entries remain current and reflect the latest threat intelligence.
    To delve deeper into the entries within an external dynamic list, you can review the contents directly from the external dynamic list configuration. This might involve inspecting the external dynamic list's source file, which you can access by clicking on the URL associated with the external dynamic list. The contents of the external dynamic list source file provide a comprehensive view of the listed indicators and their details.
    Regular monitoring of these entries is vital to ensure the effectiveness of your configuration's threat prevention capabilities. Review the entries periodically, cross-reference them with known threat databases, and validate their relevance to your organization's security posture.
    Before you Enforce Policy on an External Dynamic List, view the contents of an external dynamic list to check if it contains certain IP addresses, domains, or URLs. The entries displayed are based on the version of the external dynamic list that was most recently retrieved.
    Follow these steps to view the contents of an external dynamic list to check if it contains certain IP addresses, domains, or URLs.

    Cloud Managed

    View the contents of an external dynamic list to check if it contains certain IP addresses, domains, or URLs.
    1. Select
      Manage
      Configuration
      NGFW and
      Prisma Access
      Objects
      External Dynamic Lists
      .
    2. Select the external dynamic list you want to view.
    3. Check the
      List Entries
       and
      Exceptions
       and view the objects that were retrieved from the list.
      The list might be empty if:
    4. Enter an IP address, domain, or URL (depending on the type of list) in the search field to check if it’s in the list. Exclude entries from an external dynamic list based on which IP addresses, domains, and URLs you need to block or allow.

    Exclude Entries from an External Dynamic List

    As you view the entries of an external dynamic list, you can exclude up to 100 entries from the list. The ability to exclude entries from an external dynamic list gives you the option to enforce policy on some (but not all) of the entries in a list. This is helpful if you cannot edit the contents of an external dynamic list (such as the Palo Alto Networks High-Risk IP Addresses feed) because it comes from a third-party source.
    Follow these steps to exclude entries from an external dynamic list to enforce policy on some (but not all) of the entries in a list.
    2. Select up to 100 entries to manually exclude from the list or manually add a list exception.
      • You cannot save your changes to the external dynamic list if you have duplicate entries in the Manual Exceptions list. To identify duplicate entries, look for entries with a red underline.
      • A manual exception must match a list entry exactly. Additionally, you cannot exclude a specific IP address from within an IP address range. To exclude a specific IP address from an IP address range, you must add each IP address in the range as a list entry and then exclude the desired IP address.
        Exclusion of an individual IP address from an IP address range is not supported.
    3. Save your changes.

    PAN-OS & Panorama

    View the contents of an external dynamic list directly on the firewall to check if it contains certain IP addresses, domains, or URLs.
    1. Select
      Objects
      External Dynamic Lists
      .
    2. Click the external dynamic list you want to view.
    3. Click
      List Entries and Exceptions
       and view the objects that the firewall retrieved from the list.
      The list might be empty if:
      • The EDL has not yet been applied to a Security rule. To apply an EDL to a Security rule and populate the EDL, see Enforce Policy on an External Dynamic List.
      • The firewall has not yet retrieved the external dynamic list. To force the firewall to retrieve an external dynamic list immediately, Retrieve an External Dynamic List from the Web Server.
      • The firewall is unable to access the server that hosts the external dynamic list. Click
        Test Source URL
         to verify that the firewall can connect to the server.
    4. Enter an IP address, domain, or URL (depending on the type of list) in the filter field and Apply Filter ( ) to check if it’s in the list. Exclude entries from an external dynamic list based on which IP addresses, domains, and URLs you need to block or allow.
