802.11i offers strong security.

• A. TRUE
• B. FALSE
• C. Depends on implementation
• D. Not defined

Answer: (A)

802.11i raises WLAN security by standardizing strong cryptography and authentication. It introduces the Robust Security Network (RSN) and requires AES-based encryption (CCMP) for protecting data, which is far stronger than the old WEP or TKIP approaches. AES-CCMP provides both confidentiality and integrity on a per-packet basis, making it much harder for attackers to tamper with or decrypt traffic. Authentication is also strengthened, typically through a 4-way handshake and support for 802.1X/EAP, delivering strong mutual authentication in enterprise environments (with a solid PSK option for smaller networks). Taken together, when deployed as WPA2 with AES-CCMP and proper authentication, 802.11i offers strong security. If legacy, weaker options are used or keys are misconfigured, security can be undermined, but the standard itself is built to be strong.
