Why IoT security is critical in IOT Protocols - Test Your Understanding

Practice - 5 Tasks

1fill in blank

easy

Complete the code to identify the main reason IoT devices need security.

IOT Protocols

if device.is_connected and device.[1]:
    alert('Security risk detected')

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Choosing a property that only shows if device is online, not if it is vulnerable.

The key reason IoT devices need security is if they have vulnerabilities that attackers can exploit.

Complete the code to check if an IoT device's data is protected.

IOT Protocols

if device.data.[1] == 'encrypted':
    print('Data is safe')

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'status' or 'state' which do not specify data protection.

Checking if the data format is 'encrypted' helps ensure data protection.

Fix the error in the code that checks device authentication.

IOT Protocols

if device.[1]() == True:
    allow_access()

Drag options to blanks, or click blank then click option'

Cauth

Dauthentication

💡 Hint

Common Mistakes

Using 'auth' or 'authentication' which are not callable methods.

The correct method to check authentication is 'authenticate()'. Others are invalid method names.

4fill in blank

hard

Fill both blanks to create a condition that checks if device firmware is outdated and needs update.

IOT Protocols

if device.firmware_version [1] latest_version and device.[2] == True:
    update_firmware()

Drag options to blanks, or click blank then click option'

A<

B>

Cneeds_update

💡 Hint

Common Mistakes

Using '>' instead of '<' for version comparison.

The device firmware is outdated if its version is less than the latest version and it needs update.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps device IDs to their status if they are online and secure.

IOT Protocols

device_status = {device.[1]: device.[2] for device in devices if device.[3] and device.is_secure}

Drag options to blanks, or click blank then click option'

Cis_online

Dis_active

Attempts:

💡 Hint

Common Mistakes

Using 'is_active' instead of 'is_online' which may not reflect connectivity.

This comprehension creates a dictionary of device IDs to their status only for devices that are online and secure.
