Question: In Generic Authentication Architecture (GAA), when a Network Application Function (NAF) requests one or more User Security Settings (USSs) from the Bootstrapping Server Function (BSF) and the BSF has a defined local policy for that NAF, what is the primary implication for the BSF's handling of the request?
Option 1: The BSF ignores its local policy since the NAF requested USSs.
Option 2: The BSF applies its local policy to enforce access control related to the requested USSs.
Option 3: The BSF automatically denies the USS request due to the presence of a local policy.
Option 4: The BSF requests additional authentication from the UE before proceeding.
Explanation: In the context of GAA, when a NAF requests USSs and the BSF has a local policy in place for that NAF, the primary implication is that the BSF will apply its local policy. This application of policy is crucial for enforcing access control measures specifically related to the existence and handling of the requested User Security Settings (USSs). This ensures that the security settings are managed in accordance with the predefined rules for that particular Network Application Function, thereby maintaining the integrity of the network's security framework.
