Lesson 7: Challenges of IoT: Security and Privacy Concerns
Discuss the security and privacy challenges associated with IoT devices.
What you'll learn
- Identify at least three different security risks associated with IoT devices, such as weak passwords or unencrypted data, from a list of examples.
- Explain how a hacker could potentially use a compromised IoT device, like a smart refrigerator, to gain access to a user's personal information or network.
- Apply at least two different strategies, such as changing default passwords or updating software, to improve the security of a hypothetical IoT device setup.
- Analyze a scenario involving an IoT device and determine whether the device's data collection practices raise privacy concerns, justifying the answer with at least two reasons.

Key Concepts & Vocabulary
TermDefinitionExample
IoT SecurityThe methods used to protect IoT devices and their networks from being hacked, controlled by outsiders, or damaged. It's like putting a strong lock on your digital front door.Using a strong, unique password on your home Wi-Fi network to stop strangers from connecting to your smart lights or security camera.
IoT PrivacyThe control you have over what personal information your IoT devices collect, use, and share about you. It's about your right to keep your personal life from being exposed or sold.A smart thermostat company collects data on when you are home and sells that information to a marketing company without your permission. This is a privacy violation.
VulnerabilityA weakness in a device's software or hardware that a hacker can use to g...

Core Syntax & Patterns
Secure Password Policy
password_is_secure = (length >= 12) AND (has_uppercase) AND (has_lowercase) AND (has_number) AND (has_symbol)
This is a rule for creating strong passwords. A secure password should be long and use a mix of different character types to make it very hard for hackers to guess. Always use a unique password for each IoT device.
Two-Factor Authentication (2FA)
login_success = check_password(password) AND check_second_factor(code)
This adds a second layer of security beyond just a password. After you enter your password, you have to provide a second piece of proof, like a code sent to your phone. This means even if a hacker steals your password, they still can't get in.

Challenging
A new smart doorbell app asks for permission to access your location, your camera, your microphone, and your phone's contact list. Using the 'Principle of Least Privilege', which permission is the most questionable and should likely be denied?
A.Location, to know where the doorbell is.
B.Camera, to see who is at the door.
C.Microphone, to speak to the person at the door.
D.Contact list, as the doorbell does not need to call your friends.
Challenging
Your smart fridge offers a new feature: it will scan your food and automatically add items to your online grocery cart when you're running low. To enable this, you must link your grocery store account. What is the primary privacy trade-off you are making for this convenience?
A.The fridge might get a virus from the grocery store's website.
B.The fridge will use more electricity to scan the food.
C.You are giving the fridge company and grocery store detailed data about your family's eating habits.
D.Your grocery bills might go up because the fridge orders expensive brands.
Challenging
A friend sets up a new smart security camera. They use the password 'Fluffy123!', enable 2FA, and install all updates. However, they place the camera facing a window that looks directly into their neighbor's living room. Which IoT challenge have they failed to consider properly?
A.IoT Security, because their password is too weak.
B.Data Encryption, because the video feed is not scrambled.
C.IoT Privacy, because they are collecting data about people without their consent.
D.Default Passwords, because they forgot to change the original password.
