Question 1

Which encryption protocol was introduced to replace the vulnerable WEP standard in wireless networks?

Accepted Answer

WPA (Wi-Fi Protected Access)

Answer

WPA was specifically designed as an interim replacement for WEP, using TKIP for stronger encryption while maintaining backward compatibility.

Question 2

What encryption algorithm does WPA2 use to secure wireless communications?

Accepted Answer

AES with CCMP

Answer

WPA2 uses AES (Advanced Encryption Standard) with CCMP (Counter Mode CBC-MAC Protocol), providing much stronger security than WEP's RC4.

Question 3

What is a rogue access point in network security?

Accepted Answer

An unauthorized wireless access point installed on a network without admin approval

Answer

A rogue access point is an unauthorized AP connected to a network, which attackers or insiders can use to bypass perimeter security and intercept traffic.

Question 4

What does SSID stand for in the context of wireless networking?

Accepted Answer

Service Set Identifier

Answer

SSID stands for Service Set Identifier, which is the name that identifies a specific wireless network and is broadcast in beacon frames.

Question 5

Which IEEE standard defines port-based Network Access Control (NAC) used in enterprise wireless authentication?

Accepted Answer

IEEE 802.1X

Answer

IEEE 802.1X provides port-based NAC, requiring devices to authenticate (often via RADIUS) before gaining network access, commonly used in WPA2-Enterprise.
