1. A method of operating a wireless communication network, the method comprising:
by enforcement points in the wireless communication network:
applying access control policies for network slices in the wireless communication network to access attempts initiated by user equipment;
generating Key Performance Indicators (KPIs) that characterize results of the access attempts for the network slices; and
sending the KPIs to local policy sources in the wireless communication network;
by the local policy sources in the wireless communication network:
generating local Quality of Trust (QoT) values for the wireless communication network based on the KPIs, wherein the local QoT values indicate a level of security for corresponding ones of the network slices;
generating updates to the access control policies based on the local QoT values;
sending the updates to the enforcement points; and
sending the KPIs to a global policy source;
by the global policy source in the wireless communication network:
generating a global QoT value for the network slices based on the KPIs, wherein the global QoT value indicates a global level of security for the wireless communication network;
generating additional updates to the access control policies for the network slices based on the global QoT; and
sending the additional changes to the enforcement points.
