Question 1

What is the primary function of a Virtual Private Network (VPN)?

Accepted Answer

To create an encrypted tunnel for data transmission, protecting privacy and security on untrusted networks

Answer

A VPN creates an encrypted tunnel between your device and a VPN server, protecting data from interception on untrusted networks and masking your IP address from websites.

Question 2

What is the difference between WPA2 and WPA3 wireless security protocols?

Accepted Answer

WPA3 provides stronger encryption, protection against offline dictionary attacks, and individualized data encryption for each device on the network

Answer

WPA3 improves upon WPA2 with Simultaneous Authentication of Equals (SAE) that prevents offline dictionary attacks, individualized encryption per device, and mandatory Protected Management Frames.

Question 3

What is ARP spoofing and how does it threaten network security?

Accepted Answer

An attack that manipulates the Address Resolution Protocol to redirect network traffic through the attacker's device

Answer

ARP spoofing sends falsified ARP messages to link the attacker's MAC address with a legitimate IP address, causing traffic intended for that IP to be sent to the attacker instead.

Question 4

Why should you disable Wi-Fi auto-connect on your mobile devices?

Accepted Answer

Auto-connect may join malicious networks that impersonate trusted ones, exposing your data to attackers

Answer

Auto-connect can cause your device to join rogue access points that mimic the names of networks you have previously connected to, enabling attackers to intercept your traffic.

Question 5

What is network segmentation and why is it important for security?

Accepted Answer

Dividing a network into isolated segments to contain breaches and limit attacker movement between segments

Answer

Network segmentation divides a network into separate zones with access controls between them, limiting the lateral movement of attackers and containing the impact of a security breach.
