A Robust Security Network (RSN) is defined by the IEEE 802.11i standard and is designed to provide a framework for secure wireless LAN communications. One of the primary criteria for a network to qualify as an RSN is that WEP (Wired Equivalent Privacy) must not be used for encryption, as WEP has well-known vulnerabilities and is considered insecure. RSN-compliant networks must use either CCMP (AES) or GCMP for encryption and 802.1X/EAP or WPA2-Personal for authentication.

Incorrect:

A. Token cards are not part of RSN criteria.

B. Dynamic WEP is still WEP and disqualifies RSN status.

D. WPA-Personal may be supported, but alone does not define an RSN.

E. SSHv1 concerns device management security, not RSN qualification.

When using a wireless aggregator to combine packet captures from channels 1, 6, and 11 (the three non-overlapping 2.4 GHz channels), you're most likely analyzing multi-channel behavior. This is particularly relevant when troubleshooting roaming issues, such as fast secure roaming (e.g., 802.11r). These captures help determine whether authentication or association events occur smoothly across APs operating on different channels.

Incorrect:

A. Adapter failure doesn't require multi-channel capture.

B. Interference location is typically single-channel and spectrum-analysis focused.

D. Narrowband DoS attacks are also usually identified using RF spectrum analysis, not packet capture across all channels.

Though AES-CCMP is secure and 802.1X authentication is strong, LEAP is inherently weak because:

B. LEAP uses MS-CHAPv1, making it vulnerable to offline dictionary attacks once challenge/response exchanges are captured.

F. Layer 1 DoS attacks (such as RF jamming or interference) can be launched regardless of authentication mechanisms.

Incorrect:

A. AES-CCMP resists encryption cracking.

C. Peer-to-peer at Layer 3 is unrelated to LEAP or 802.1X vulnerabilities.

D. Application-layer eavesdropping is mitigated if encryption is properly implemented.

E. Session hijacking is more difficult with proper authentication and encryption in place.

Open networks with captive portals do not provide link-layer encryption, so:

A. Man-in-the-Middle (MitM): Attackers can intercept or modify traffic between the user and the legitimate network (especially before HTTPS negotiation).

B. Wi-Fi phishing: Evil twin APs may mimic the legitimate hotspot and show a fake captive portal, stealing user credentials or prompting malicious downloads.

Incorrect:

C. Management interface exploits target device admin panels, not typical client users.

D. UDP port redirection and

E. IGMP snooping are network-layer behaviors, not common user-targeted attacks.
