CompTIA Security+ Certification SY0-601: The Total Course - Wi-Fi Hardening

The video tutorial covers Wi-Fi security, focusing on RADIUS authentication and various protocols like EAP and EAP-TLS. It discusses additional security measures such as MAC filtering and WPA3, and explains the concept of captive portals as forward proxies. The tutorial concludes with a practical guide on configuring a wireless router to enhance network security.

What is a key advantage of using RADIUS authentication over a pre-shared key?

• It is easier to set up.

• It provides a single passphrase for all users.

• It allows for centralized authentication with unique credentials.

• It requires no additional hardware.

Which protocol requires both server and client to have PKI certificates?

• EAP-FAST

• EAP-TLS

• EAP-TTLS

• WPA2

What is the role of a shared secret in RADIUS server authentication?

• To encrypt data between devices

• To allow the access point to send authentication requests

• To replace the need for a password

• To configure the network's SSID

What is a benefit of hiding the SSID of a wireless network?

• It eliminates the need for a password.

• It increases the network speed.

• It makes the network invisible to casual users.

• It prevents all unauthorized access.

Which security measure involves allowing or denying devices based on their hardware address?

• SSID hiding

• MAC address filtering

• RADIUS authentication

• WPA3 encryption

Why is it recommended to use WPA3 over older security protocols?

• It is compatible with all devices.

• It offers enhanced security features.

• It is easier to configure.

• It requires no password.

What should be done if a device does not support WPA3?

• Replace the device with one that supports WPA3

• Continue using WPA2

• Use a pre-shared key

• Disable wireless security

What is a potential risk of extending the wireless range beyond necessary limits?

• Improved signal strength

• Increased network speed

• Higher power consumption

• Exposure to unauthorized access

What is a captive portal primarily used for?

• Blocking unauthorized devices

• Extending wireless range

• Providing a landing page for network access

• Encrypting network traffic

What is a common feature of a captive portal in public Wi-Fi hotspots?

• Unlimited bandwidth

• A landing page requiring user interaction

• Automatic device configuration

• Free access without terms
