Exam-style question
Try this first
Explain how a wireless network can be secured using WPA or WPA2, disabled SSID broadcast and a MAC address allow list. State what each measure is intended to do.
Model answer
What a good answer should say
- WPA or WPA2 provides strong encryption for data transmitted over the wireless network, helping to prevent the transmitted data from being understood by unauthorised parties.
- Disabling SSID broadcast prevents the network name from being broadcast normally, making the network less visible to users searching for networks.
- A MAC address allow list restricts access to devices whose MAC addresses have been included on the list.
Explanation
Why this works
The three measures provide different types of protection. WPA or WPA2 protects the confidentiality of transmitted data.
Disabling SSID broadcast reduces the visibility of the network. A MAC address allow list controls which device addresses are permitted to connect.
A complete answer should distinguish these purposes rather than treating them as interchangeable.
