Domain 2.0 security

Question 1

Question 17:
What encryption type was used by WPA to better secure wireless networks than WEP?

Answer 1

Correct Answer: TKIP
WPA (Wi-Fi Protected Access) uses RC4 with TKIP (Temporal Key Integrity Protocol) to address vulnerabilities in WEP (Wired Equivalent Privacy). TKIP dynamically changes keys to secure communication.

Question 2

How to prevent unauthorized devices (like Bob’s Laptop) from connecting to your wireless network?

Answer 2

Disable WPS

WPS (Wi-Fi Protected Setup) simplifies device connection but is vulnerable to brute-force attacks. Disabling WPS prevents unauthorized devices from connecting even if they know your WPS PIN.

Question 3

Question 27:
Which encryption uses a 128-bit key but is weak due to a 24-bit initialization vector?

Answer 3

WEP
Explanation:
WEP uses a 24-bit initialization vector (IV) for key security, but this makes it susceptible to attacks. WPA and WPA2 replaced WEP with more secure encryption methods like TKIP and AES.

Question 4

Question 50:
Which policy dictates password complexity requirements for a wireless network?

Answer 4

Password Policy
Explanation:
A password policy defines rules like minimum length, complexity, and periodic changes to ensure secure access.

Question 5

Question 58:
What security control helps administrators deploy configuration settings across devices?

Answer 5

Correct Answer: GPO
Explanation:
Group Policy Object (GPO) in Windows allows centralized control of device configurations, ensuring consistency and security for users and systems

Question 6

What cryptographic attack uses a list of passwords to unlock a file?

Answer 6

Correct Answer: Dictionary Attack
Explanation:
A dictionary attack tries common passwords from a predefined list, unlike brute-force attacks, which try every possible combination.
