1

Create cybersecurity features dictionary

Create a dictionary called cybersecurity_features with these exact entries: 'Firewall' with description 'Monitors and controls incoming and outgoing network traffic.', 'Encryption' with description 'Protects data by encoding it during transmission.', 'Authentication' with description 'Verifies the identity of users and devices.', 'Intrusion Detection' with description 'Detects unauthorized access or attacks.', and 'Software Updates' with description 'Regularly updates system software to fix vulnerabilities.'.

# Create the cybersecurity_features dictionary with exact entries
# Your code here

Hint

Use a Python dictionary with keys as feature names and values as their descriptions exactly as given.

2

Add critical importance level

Create a variable called critical_level and set it to the integer 50. This will be used as the minimum description length to consider a feature critical.

EV Technology

cybersecurity_features = {
    'Firewall': 'Monitors and controls incoming and outgoing network traffic.',
    'Encryption': 'Protects data by encoding it during transmission.',
    'Authentication': 'Verifies the identity of users and devices.',
    'Intrusion Detection': 'Detects unauthorized access or attacks.',
    'Software Updates': 'Regularly updates system software to fix vulnerabilities.'
}
# Create critical_level variable and set it to 50
# Your code here

Hint

Just assign the number 50 to the variable named critical_level.

3

Select critical cybersecurity features

Use a dictionary comprehension to create a new dictionary called critical_features that includes only those entries from cybersecurity_features where the description length is greater than critical_level.

EV Technology

cybersecurity_features = {
    'Firewall': 'Monitors and controls incoming and outgoing network traffic.',
    'Encryption': 'Protects data by encoding it during transmission.',
    'Authentication': 'Verifies the identity of users and devices.',
    'Intrusion Detection': 'Detects unauthorized access or attacks.',
    'Software Updates': 'Regularly updates system software to fix vulnerabilities.'
}
critical_level = 50
# Create critical_features dictionary using comprehension for descriptions longer than critical_level
# Your code here

Hint

Use a dictionary comprehension with for feature, desc in cybersecurity_features.items() and filter by len(desc) > critical_level.

4

Add cybersecurity summary

Create a string variable called summary with this exact text: 'Cybersecurity is essential for connected EVs to protect data, ensure safety, and maintain trust.'

EV Technology

cybersecurity_features = {
    'Firewall': 'Monitors and controls incoming and outgoing network traffic.',
    'Encryption': 'Protects data by encoding it during transmission.',
    'Authentication': 'Verifies the identity of users and devices.',
    'Intrusion Detection': 'Detects unauthorized access or attacks.',
    'Software Updates': 'Regularly updates system software to fix vulnerabilities.'
}
critical_level = 50
critical_features = {feature: desc for feature, desc in cybersecurity_features.items() if len(desc) > critical_level}
# Create summary string with the exact given text
# Your code here

Hint

Assign the exact text to the variable summary using quotes.

Practice

1. Why is cybersecurity important for connected electric vehicles (EVs)?

easy

A. To protect the vehicle from hacking and unauthorized access

B. To improve the vehicle's fuel efficiency

C. To increase the vehicle's speed

D. To reduce the vehicle's battery size

Solution

1. Step 1: Understand the role of cybersecurity in connected EVs

   Cybersecurity protects the vehicle's systems and data from hackers and unauthorized users.

2. Step 2: Identify the correct purpose among options

   Only To protect the vehicle from hacking and unauthorized access mentions protection from hacking and unauthorized access, which is the main goal of cybersecurity.

3. Final Answer:

   To protect the vehicle from hacking and unauthorized access -> Option A

4. Quick Check:

   Cybersecurity = Protect from hacking [OK]

Hint: Cybersecurity means protection from hackers [OK]

Common Mistakes:

• Confusing cybersecurity with vehicle performance features
• Thinking cybersecurity improves speed or battery size

2. Which of the following is a good cybersecurity practice for connected EVs?

easy

A. Connecting only to public Wi-Fi networks

B. Using weak passwords like '1234'

C. Regularly updating the vehicle's software

D. Sharing your vehicle access codes with strangers

Solution

1. Step 1: Review common cybersecurity practices

   Good practices include strong passwords, software updates, and avoiding unsecured networks.

2. Step 2: Identify the correct practice from options

   Regularly updating the vehicle's software is correct because updating software fixes security issues and protects the vehicle.

3. Final Answer:

   Regularly updating the vehicle's software -> Option C

4. Quick Check:

   Software updates = Better security [OK]

Hint: Keep software updated to stay secure [OK]

Common Mistakes:

• Choosing weak passwords
• Using public Wi-Fi without protection
• Sharing access codes carelessly

3. Consider this code snippet for an EV's security system:

def check_access(password):
    if password == 'Secure123':
        return 'Access granted'
    else:
        return 'Access denied'

print(check_access('secure123'))

What will be the output?

medium

A. Access granted

B. SyntaxError

C. None

D. Access denied

Solution

1. Step 1: Understand the password check logic

   The function compares the input password exactly to 'Secure123' with case sensitivity.

2. Step 2: Check the input password 'secure123'

   The input 'secure123' differs in case from 'Secure123', so the condition fails and returns 'Access denied'.

3. Final Answer:

   Access denied -> Option D

4. Quick Check:

   Case mismatch causes denial [OK]

Hint: Password check is case sensitive [OK]

Common Mistakes:

• Ignoring case sensitivity in password comparison
• Assuming 'secure123' matches 'Secure123'
• Expecting syntax errors from correct code

4. This code is intended to block unauthorized access to an EV:

def authenticate(user_input):
    if user_input = 'EVUser':
        return 'Access allowed'
    else:
        return 'Access denied'

What is the error in this code?

medium

A. Using '=' instead of '==' for comparison

B. Missing return statement

C. Incorrect indentation

D. Function name is invalid

Solution

1. Step 1: Identify the comparison operator in the if statement

   The code uses '=' which is an assignment operator, not a comparison operator.

2. Step 2: Understand correct syntax for comparison

   To compare values, '==' must be used instead of '='.

3. Final Answer:

   Using '=' instead of '==' for comparison -> Option A

4. Quick Check:

   Comparison needs '==' not '=' [OK]

Hint: Use '==' to compare, '=' to assign [OK]

Common Mistakes:

• Confusing assignment '=' with comparison '=='
• Ignoring syntax errors from wrong operator
• Assuming function names cause errors

5. You want to secure your connected EV against unauthorized remote access. Which combination of actions is best?

hard

A. Turn off all security features to improve speed

B. Use strong passwords, update software regularly, avoid public Wi-Fi

C. Use simple passwords, connect only to public Wi-Fi, ignore updates

D. Share your access code with trusted friends, disable software updates

Solution

1. Step 1: Identify effective cybersecurity actions

   Strong passwords, regular updates, and avoiding unsecured networks protect against hacking.

2. Step 2: Evaluate each option's security impact

   Use strong passwords, update software regularly, avoid public Wi-Fi includes all good practices; others weaken security or cause risks.

3. Final Answer:

   Use strong passwords, update software regularly, avoid public Wi-Fi -> Option B

4. Quick Check:

   Strong passwords + updates + safe networks = Secure EV [OK]

Hint: Combine strong passwords, updates, and safe networks [OK]

Common Mistakes:

• Sharing access codes too freely
• Ignoring software updates
• Using weak passwords or unsafe networks
