Wireless Network Security Quiz

What is the primary purpose of wireless network security?

• To reduce network costs

• To improve signal strength

• To protect against unauthorised access and breaches

• To increase network speed

Answer explanation

The primary purpose of wireless network security is to protect against unauthorized access and breaches, ensuring that only authorized users can access the network and its resources.

Which wireless security protocol is considered obsolete due to its vulnerabilities?

• WPA2

• WPA

• WPA3

• WEP

Answer explanation

WEP (Wired Equivalent Privacy) is considered obsolete due to significant vulnerabilities that allow attackers to easily compromise network security. In contrast, WPA2 and WPA3 offer stronger security measures.

What does WPA stand for?

• Wireless Protected Access

• Wi-Fi Protected Access

• Wideband Protected Access

• Wired Protected Access

Answer explanation

WPA stands for Wi-Fi Protected Access, which is a security protocol designed to secure wireless networks. The other options do not accurately represent the standard used for protecting Wi-Fi connections.

Which encryption method is used by WPA2?

• RSA

• TKIP

• AES

• RC4

Answer explanation

WPA2 uses AES (Advanced Encryption Standard) for encryption, providing stronger security compared to TKIP and RC4, which are older methods. AES is the correct choice for WPA2 encryption.

What is a common feature of WPA3?

• Weaker encryption

• Use of RC4 encryption

• Simpler device configuration

• Increased compatibility with older devices

Answer explanation

WPA3 features simpler device configuration, making it easier for users to set up secure connections. This is a significant improvement over previous standards, unlike weaker encryption or outdated protocols like RC4.

Which of the following is NOT a way to secure Wi-Fi networks?

• Using outdated protocols

• Using encryption methods

• Activating the router firewall

• Disabling SSID broadcast

Answer explanation

Using outdated protocols is NOT a way to secure Wi-Fi networks, as they are vulnerable to attacks. In contrast, using encryption methods, activating the router firewall, and disabling SSID broadcast enhance security.

What is the role of a VPN in wireless network security?

• To increase network speed

• To provide free internet access

• To encrypt data and protect privacy

• To disable firewalls

Answer explanation

A VPN encrypts data transmitted over a wireless network, ensuring that sensitive information remains private and secure from potential eavesdroppers. This is crucial for protecting user privacy in unsecured networks.

Which authentication mechanism involves using a password plus a physical token?

• Multi-Factor Authentication (MFA)

• Password-Based Authentication

• Passwordless Authentication

• Single Sign-On (SSO)

Answer explanation

Multi-Factor Authentication (MFA) combines something you know (a password) with something you have (a physical token), enhancing security beyond just a password.

What is the main function of a Unified Threat Management (UTM) system?

• To provide internet access

• To combine multiple security functions into one device

• To increase network bandwidth

• To disable encryption

Answer explanation

The main function of a Unified Threat Management (UTM) system is to combine multiple security functions into one device, streamlining security management and enhancing protection against various threats.

Which Wi-Fi security threat involves creating a fake access point to steal information?

• DNS-cache poisoning

• Evil Twin Attacks

• Piggybacking

• IP Spoofing

Answer explanation

Evil Twin Attacks involve creating a fake access point that mimics a legitimate one, tricking users into connecting. This allows attackers to intercept sensitive information, making it a significant Wi-Fi security threat.
