Given: ABC Company secures their network with WPA2-Personal authentication and AES-CCMP encryption.
What part of the 802.11 frame is always protected from eavesdroppers by this type of security?
All MSDU contents
All MPDU contents
All PPDU contents
All PSDU contents
In WPA2-Personal with AES-CCMP:
The MSDU (MAC Service Data Unit), which includes the payload from Layer 3 and above, is encrypted.
This protects the actual application data (e.g., web content, email).
Frame headers (MAC headers) are not encrypted.
Incorrect:
B. MPDU includes MAC headers, which are not encrypted.
C. PPDU includes preamble and physical-layer components, which are never encrypted.
D. PSDU includes the MAC header and frame body; again, headers are not encrypted.
