Question: What is a key security requirement for Premises Radio Access Stations (PRAS) in the 5G system, in addition to supporting a mechanism to minimize security risks?
Option 1: Providing differentiated routing and QoS for various destinations without compromising user privacy.
Option 2: Offering a level of security equivalent to regular 5G base stations, with operator-controlled security policy.
Option 3: Enabling direct connections using only operator-managed credentials for all communications.
Option 4: Allowing unrestricted access to mitigate repeated unauthorized attempts to access PIN Elements.
Explanation: This is correct because the 5G system requires PRAS (and its associated backhaul connectivity) to provide a security level equivalent to regular 5G base stations, while also enabling the network operator associated with the PRAS to control its security policy. This ensures robust security measures are in place for PRAS deployments within the 5G ecosystem.
