4.3 Flashcards
Whats WPA?
(Wi-Fi Protected Access) It uses TKIP for security.
What does TKIP do?
It mixes the keys and combines the secret root key with the initialization vector(IV). It also adds sequence counter to prevent replay attacks. Then it implements a 64-bit Message Integrity Check which protects against tampering.
What does WPA2 do?
WPA2 uses AES and CCMP to be able to encrypt the traffic going through our wireless networks.
What are CCMP security services?
Data confidentiality(by using AES), authentication and access control.
What did CCMP-AES replace?
TKIP -RC4
What does EAP stand for?
(Extensible Authentication Protocol) It’s an authentication framework and it has many different ways to authenticate based on RFC standards.
What do WPA and WPA2 use for authentication?
WPA and WPA2 use five EAP types as authentication.
Whats EAP-FAST?
(EAP Flexible Authentication via Secure Tunneling) It’s an EAP which is light and secured.
Whats EAP-TLS?
(EAP Transport Layer Security) It’s an EAP which has strong security and wide adoption.
Whats EAP-TTLS?
(EAP-Tunneled Transport Layer Security)It’s an EAP which supports other authentication protocols in a TLS tunnel.
Whats PEAP?
(Protected EAP) It was created by Cisco Microsoft and RSA security and it encapsulates EAP in a TLS tunnel(combined a security channel and EAP.
What is share/open?
Open system means no authentication password is required.
Whats preshared key?
WPA2-persoanl / WPA-PSK(preshared key) is a configuration for a network in a house or office and everyone uses the same 256-bit key.
Whats the difference between WPA2-Persoanl and WPA2-Enterprise?
In WPA2-Personal everyone uses the same 256-bit key but WPA2-Enterprise authenticates users individually with an authentication server (ex:RADIUS)
Whats Geofencing?
It restricts or allows features when the device is in a particular area(like camera or authentication in specific area.
