Question: What is the primary security concern addressed by integrity protection for the "application/mbms-msk-response+xml" media type in MBMS, and how is it mitigated?
Option 1: Data privacy breach; Mitigated through encryption as per RFC 3023.
Option 2: Denial of Service (DoS) attack; Mitigated through procedures described in a generic security standard.
Option 3: Man-in-the-Middle (MitM) attack; Mitigated using Secure Sockets Layer/Transport Layer Security (SSL/TLS).
Option 4: Denial of Service (DoS) attack; Mitigated through integrity protection procedures specific to MBMS security for preventing format modifications.
Explanation: The primary security concern for the "application/mbms-msk-response+xml" media type is a Denial of Service (DoS) attack from format modifications. This is mitigated through integrity protection measures, focusing on ensuring the authenticity and integrity of response codes in MBMS operations to prevent service disruptions.
