What happens first association or authentication?
Yes, in modern 802.11 there is an open authentication that takes place before the association request/response. This is also prior to any sort of 802.1X authentication or WPA/WPA2 key exchange.
Which comes first in joining an access point association or authentication?
802.11 authentication is the first step in network attachment. 802.11 authentication requires a mobile device (station) to establish its identity with an Access Point (AP) or broadband wireless router.
What authentication methods does the 802.11 standard provide?
There are three main methods of authentication that are used on today’s wireless LANs:
- open authentication.
- shared authentication.
- EAP (Extensible Authentication Protocol) authentication.
What is the purpose of wireless network authentication?
Implementing authentication enables you to secure a network so that only users with the proper credentials can access network resources. It’s not an all-or-nothing deal, of course; you can use authentication to restrict or enable what a specific user can do once inside the network as well.
What is WiFi handshake?
The 4-way handshake is used to authenticate the WiFi client and encrypt all communications with the access point. The handshake is established by exchanging EAPoL frames between the WPA supplicant running on the client and the authenticator running on the access point.
Terms and Questions
| Term | Definition |
|---|---|
| rogue access point | An unauthorized AP that allows an attacker to bypass many of the network security configurations and opens the network and its users to attacks. |
| Service Set Identifier (SSID) | The alphanumeric user-supplied network name of a WLAN. |
What are the different methods of authentication?
What are the types of authentication?
- Single-Factor/Primary Authentication.
- Two-Factor Authentication (2FA)
- Single Sign-On (SSO)
- Multi-Factor Authentication (MFA)
- Password Authentication Protocol (PAP)
- Challenge Handshake Authentication Protocol (CHAP)
- Extensible Authentication Protocol (EAP)
What is the best wireless authentication method?
WPA stands for WiFi Protected Access. This authentication method uses different encryption algorithms to encrypt the transport. Therefore, this type of network cannot be forged easily, unlike open networks, and users get privacy. Today, WPA2 is probably the most commonly used method to secure WiFi networks.
What is the most secure WiFi encryption?
WPA2-PSK
WPA2-PSK (AES): This is the most secure option. It uses WPA2, the latest Wi-Fi encryption standard, and the latest AES encryption protocol.
How does the 802.11 Authentication process work?
Once compatible networks are discovered the mobile station will attempt low-level 802.11 authentication with compatible APs. Keep in mind that 802.11 authentication is not the same as WPA2 or 802.1X authentication mechanisms which occur after a mobile station is authenticated and associated.
What do you need to know about 802.11 Association?
Before the station can send traffic through an access point, it must have established a connection state. The station must be in an authenticated and associated state before connection is established. The station and AP will exchange a series of 802.11 management frames in order to get to an authenticated and associated state.
Do you need dynamic keying for 802.11 Association?
Note: If WPA/WPA2 or 802.1X authentication is required on the wireless network, the mobile station will not be able to send data until dynamic keying and authentication have taken place after the 802.11 Association is complete.
How does the Association process for WiFi work?
The station will have to begin the association process from the low level authentication step. At this point the station is authenticated but not yet associated.
