What is a network?

• A group of connected computers or devices that can share resources

• A type of software application

• A single computer system

• A group of isolated devices

Answer explanation

A network is defined as a group of connected computers or devices that can share resources, making the first choice the correct answer. The other options do not accurately describe the concept of a network. Word 1, Letter 4 is S.

Which of the following is a common vulnerability of IoT devices?

• Limited data collection

• Strong encryption

• Weak/Default Passwords

• Frequent updates

Answer explanation

Weak/default passwords are a common vulnerability in IoT devices, as many users do not change the factory settings, making them easy targets for attackers. This poses significant security risks. Word 1, Letter 5 is H.

Why are IoT devices particularly vulnerable compared to traditional computers?

• They often lack timely security updates

• They have more processing power

• They are more expensive

• They are less popular

Answer explanation

IoT devices are particularly vulnerable because they often lack timely security updates, leaving them exposed to new threats. Unlike traditional computers, many IoT devices do not receive regular patches, increasing their risk. Word 1, Letter 6 is i.

What is one way to protect your IoT devices?

• Ignore software updates

• Enable two-factor authentication (2FA) where available

• Disable all security features

• Use default passwords

Answer explanation

Enabling two-factor authentication (2FA) adds an extra layer of security to your IoT devices, making it harder for unauthorized users to gain access. This is a crucial step in protecting your devices from potential threats. Word 2, Letter 2 is H.

What is the purpose of using a separate Wi-Fi network for IoT devices?

• To improve device performance

• To isolate IoT devices for better security

• To increase internet speed

• To reduce electricity consumption

Answer explanation

Using a separate Wi-Fi network for IoT devices helps isolate them from the main network, enhancing security by reducing the risk of unauthorized access and potential attacks on sensitive data. Word 2, Letter 3 is i.

Which of the following is a real-world example of an IoT device breach?

• Social media scam

• Computer virus

• Email phishing

• Smart home device hacks

Answer explanation

Smart home device hacks are a clear example of IoT device breaches, where unauthorized access to devices like cameras or thermostats can lead to privacy violations and security risks. Word 2, Letter 4 is E.

What should you do immediately after purchasing an IoT device?

• Disable all security features

• Connect it to public Wi-Fi

• Change default passwords to strong, unique passwords

• Leave it in the box

Answer explanation

Immediately after purchasing an IoT device, it's crucial to change default passwords to strong, unique passwords. This helps protect the device from unauthorized access and enhances overall security. Word 3, Letter 2 is E.

What is a potential risk of using public Wi-Fi with IoT devices?

• Increased battery life

• Improved device performance

• Faster internet speed

• Data interception by unauthorized users

Answer explanation

Using public Wi-Fi with IoT devices poses a risk of data interception by unauthorized users, as these networks are often unsecured, making it easier for attackers to access sensitive information. Word 3, Letter 4 is E.
