The paper adopts a "one service = one realm" isolation strategy in Keycloak to confine potential breaches. However, as the number of Digital Twin services scales up, this approach introduces significant administrative overhead. How can the realm-per-service model be optimized or partially consolidated without sacrificing the security isolation guarantees prescribed by NIST ZTA principles?
