Wireless Network Type & Encryption

Question 1

Wireless Mesh

Answer 1

A decentralized wireless topology where each node relays data, providing redundancy and extended coverage.

Question 2

Ad Hoc

Answer 2

Also called Independent Basic Service Set (IBSS); devices connect directly to one another without a central access point, commonly used for IoT or temporary setups.

Question 3

Point-to-Point Wireless Mode

Answer 3

A wireless connection between two devices or sites using directional antennas for long-range communication.

Question 4

Infrastructure Wireless Mode

Answer 4

The most common Wi-Fi setup where clients connect through an access point for centralized communication and management.

Question 5

AES

Answer 5

A symmetric block cipher used for encrypting data in WPA2 and WPA3 wireless security protocols.

Question 6

MIC

Answer 6

Message Integrity Check: Ensures data packets haven’t been altered during transmission, providing integrity verification.

Question 7

GMAC

Answer 7

Galois Message Authentication Code: Used in WPA3 and ensures data packets haven’t been altered during transmission, providing integrity verification. Stronger method than the older MIC

Question 8

WEP

Answer 8

Wired Equivalent Privacy: An outdated and insecure encryption standard that should no longer be used.

Question 9

WPA

Answer 9

Wi-Fi Protected Access: Introduced TKIP encryption as an improvement over WEP but still considered outdated and less secure.

Question 10

WPA2

Answer 10

Wi-Fi Protected Access Version 2: Uses AES encryption with CCMP mode, providing strong confidentiality and integrity for Wi-Fi networks.

Question 11

CCMP

Answer 11

Cipher Block Chaining Message Authentication Code Protocol: A block cipher mode that combines AES encryption with MIC for security in WPA2.

Question 12

WPA3

Answer 12

Wi-Fi Protected Access Version 3: The latest standard providing stronger encryption, forward secrecy, and protection against offline password attacks using SAE.

Question 13

GCMP

Answer 13

Galois/Counter Mode Protocol: A block cipher mode combining AES encryption with MIC and GMAC integrity checks, used in WPA3 for enhanced security.
