Supply Chain Violation
The supply chain violation is accessible under Policies → Asset Policies→ Supply Chain Violation.
The supply chain violation page contains a list of assets with country of origin of NICs (COO) policies that are not allowed to connect to the system.
Any COO that are listed in this policy will make MetaDefender OT Security trigger an alert when the asset has that COO.

Supply chain violation policies are added manually by the user.
