Question 1

What is WEP (Wired Equivalent Privacy)?

Answer 1

An early encryption standard using a 40-bit key. It is outdated and vulnerable to hacking.

Question 2

What is WPA2 (WiFi Protected Access 2)?

Answer 2

A secure encryption protocol using AES with up to 256-bit keys. It is widely used and highly secure.

Question 3

How does MAC (Media Access Control) address filtering enhance security?

Answer 3

• Media Access Control address.
• Hard-coded into devices by manufacturers
• Are used to identify specific pieces of hardware

Restricts network access to devices with approved MAC addresses. Offers high security but is time-intensive to manage.

Question 4

What is the difference between one factor, two factor and three factor authentication?

Answer 4

One factor - something you know
Two factor - Something you have
Three factor - Something you are

Question 5

What are firewalls?

Answer 5

• Hardware or Software (or hybrid of both).
• Controls incoming and outgoing network traffic.
• Analyse data packets based on pre-determined set of rules

Question 6

Explain how the use of media access control (MAC) addressed can improve security?

Answer 6

The use of Media Access Control (MAC) addresses can improve security by allowing network devices to identify and control access based on each device’s unique hardware address. By filtering or allowing only specific MAC addresses to connect, unauthorized devices can be blocked from accessing the network, reducing the risk of intrusion.
