Q

What are the characteristic features of WPA2/WPA3 Enterprise mode?

A
  • Suitable for large corporate networks
  • IEEE 802.1x
  • Requires RADIUS authentication server
17
Q

What would be the best solution for securing a small network that lacks an authentication server?

A

WPA3 SAE

18
Q

IEEE standard that can be implemented in a situation where an Ethernet switch acts as an authenticator for devices that intend to connect to a network through one of its ports?

A

IEEE 802.1x

19
Q

Which of the EAP methods relies on client-side and server-side certificates for authentication and offers the highest level of security?

A

EAP-TLS

20
Q

What is EAP?

A

Extensible Authentication Protocol - authentication framework used in wireless networks.

EAP provides an authentication framework, not a specific authentication mechanism.

21
Q

What is SAE?

A

Simultaneous Authentication of Equals - used for client authentication in WPA3 personal mode. Best for securing small networks without an authentication server

22
Q

What is PSK ?

A

Pre Shared Key - used for client authentication in WPA2 personal mode. Same encryption key is used by the access point and the client

23
Q

What is WEP?

A

Wired Equivalent Privacy - Original 802.11 wireless security standard that claims to be as secure as a wired network. Weakness is it’s 24 bit initialization vector. Outdated and not secure

24
Q

What is a rogue access point?

A

Unauthorized wireless access point or wireless router that allows access to the secure network

25
Q

What is an evil twin?

A

Rogue counterfeit and unauthorized wap with the same SID as your valid one

26
Q

What is SSID?

A

Service Set Identifier - uniquely identifies the network and is the name of the wireless access point (WAP) used by the clients. Should be disabled for security

27
Q

What is WPA?

A

Wifi Protected Access - replacement for WEP using TKIP and RC4 encryption

28
Q

What is blue jacking?

A

sending unsolicited data across bluetooth

29
Q

What is blue snarfing ?

A

Taking data via bluetooth
