Date Notes
May 26, 2021 - Initial release
Sep 10, 2021 - Updated to use the new system atomics

See the Important Notes page for more information about updating workflows


Requirements

  • The following system atomics are used by this workflow:
    • Secure Firewall - Create Dynamic Object Group
    • Secure Firewall - Get Access Token
    • Secure Firewall - Get Dynamic Object Group Mappings
    • Secure Firewall - Update Dynamic Object Group Mappings
  • The following atomic actions must be imported before you can import this workflow:
    • None
  • The targets and account keys listed at the bottom of the page
  • Cisco Secure Firewall (software version 7.0 or newer)

Workflow Steps

  1. Get an access token for Secure Firewall
  2. Get the existing dynamic object group mappings
  3. Check if fetching the mappings succeeded (if not, create a new dynamic object group)
  4. Fetch the JSON from Microsoft and generate a list of records to add and to remove
  5. Check if any records need to be added (if so, add them)
  6. Check if any records need to be removed (if so, remove them)

Configuration

  • Go to Microsoft’s website to get the URL for the worldwide endpoint JSON. Click the link on the second bullet to https://endpoints.office.com/endpoints/worldwide and copy the URL into the Microsoft Endpoints URL local variable in the workflow
  • Set the Dynamic Object Group Name local variable to the name of the object group you want to update. Note that this group must be created on Firewall Management Center prior to running the workflow

Targets

Note: If your FMC is on-premises and not accessible from the internet, you will need a SecureX orchestration remote to use FMC with orchestration.
