• Defining a new "default" trust zone

Required permissions

• SYSTEM_SETTINGS_UPDATE (users need the ability to edit trust zones)

Instructions

1. By default in most tenants, the "default" trust zone is set to the Internet trust zone. The default trust zone is leveraged anytime another trust zone (that is being used in threat models) is being deleted. Any threat models where the deleted trust zone are being used will then be switched to the default trust zone. 

2. Start by creating a new trust zone that will be set to default later. Add a trust rating of 1.

3. Raise the current default trust rating for the current "default" trust zone to something higher than the new "default" trust zone. Whenever the previous "default" trust zone is removed, the new "default" trust zone will always be the trust zone with the lowest trust rating. This means that if we want to designate another "default" trust zone, it has to have the lowest trust rating.  If you have multiple trust zones with a trust rating of 1, you will need to raise all of them to a higher value. They can be lowered later. 

4. The new "default" trust zone will now be displayed in your tenant. 

5. Once complete, review any mapping files and update the unique ID and name of the default trust zone (if used in the mapping file).
