CWSP-207 Exam Dumps - CWNP Certification Questions and Answers

Token cards must be used for authentication.

Dynamic WEP-104 encryption must be enabled.

WEP may not be used for encryption.

WPA-Personal must be supported for authentication and encryption.

WLAN controllers and APs must not support SSHv1.

Transmitting a deauthentication frame to disconnect a user from the AP.

Auditing the configuration and functionality of a WIPS by simulating common attack sequences

Probing the RADIUS server and authenticator to expose the RADIUS shared secret

Cracking the authentication or encryption processes implemented poorly in some WLANs

John's bank is using an expired X.509 certificate on their web server. The certificate is on John's Certificate Revocation List (CRL), causing the user ID and password to be sent unencrypted.

John uses the same username and password for banking that he does for email. John used a POP3 email client at the wireless hot-spot to check his email, and the user ID and password were not encrypted.

John accessed his corporate network with his IPSec VPN software at the wireless hot-spot. An IPSec VPN only encrypts data, so the user ID and password were sent in clear text. John uses the same username and password for banking that he does for his IPSec VPN software.

The bank’s web server is using an X.509 certificate that is not signed by a root CA, causing the user ID and password to be sent unencrypted.

Before connecting to the bank’s website, John’s association to the AP was hijacked. The attacker intercepted the HTTPS public encryption key from the bank’s web server and has decrypted John’s login credentials in near real-time.

Offline dictionary attacks

ASLEAP

DoS

802.1X/EAP-TTLS

Open 802.11 authentication with IPSec

802.1X/PEAPv0/MS-CHAPv2

WPA2-Personal with AES-CCMP

EAP-MD5

All integrated 802.11ac adapters will work with most protocol analyzers for frame capture, including the Radio Tap Header.

Integrated 802.11ac adapters are not typically compatible with protocol analyzers in Windows laptops. It is often best to use a USB adapter or carefully select a laptop with an integrated adapter that will work.

Laptops cannot be used to capture 802.11ac frames because they do not support MU-MIMO.

Only Wireshark can be used to capture 802.11ac frames as no other protocol analyzer has implemented the proper frame decodes.

The only method available to capture 802.11ac frames is to perform a remote capture with a compatible access point.

The username is needed for Personal Access Credential (PAC) and X.509 certificate validation.

The username is an input to the LEAP challenge/response hash that is exploited, so the username must be known to conduct authentication cracking.

4-Way Handshake nonces are based on the username in WPA and WPA2 authentication.

The username can be looked up in a dictionary file that lists common username/password combinations.

RF jamming device and a wireless radio card

A low-gain patch antenna and terminal emulation software

A wireless workgroup bridge and a protocol analyzer

DHCP server software and access point software

MAC spoofing software and MAC DoS software

Intruders may obtain the passphrase with an offline dictionary attack and gain network access, but will be unable to decrypt the data traffic of other users.

A successful attack against all unicast traffic on the network would require a weak passphrase dictionary attack and the capture of the latest 4-Way Handshake for each client.

An unauthorized wireless client device cannot associate, but can eavesdrop on some data because WPA2-Personal does not encrypt multicast or broadcast traffic.

An unauthorized WLAN user with a protocol analyzer can decode data frames of authorized users if he captures the BSSID, client MAC address, and a user’s 4-Way Handshake.

Because WPA2-Personal uses Open System authentication followed by a 4-Way Handshake, hijacking attacks are easily performed.

Joe disabled his laptop’s integrated 802.11 radio and is using a personal PC card radio with a different chipset, drivers, and client utilities.

Joe’s integrated 802.11 radio is sending multiple Probe Request frames on each channel.

An ASLEAP attack has been detected on APs to which Joe’s laptop was trying to associate. The WIPS responded by disabling the APs.

Joe configured his 802.11 radio card to transmit at 100 mW to increase his SNR. The WIPS is detecting this much output power as a DoS attack.
