Unit 10 AP CSP Advanced

1. How does symmetric key encryption differ from public key encryption in terms of key usage?

• Symmetric key encryption uses multiple keys
• Symmetric key encryption uses one key for both encryption and decryption
• Public key encryption uses one key for both encryption and decryption
• Symmetric key encryption uses one key for encryption and a different key for decryption

2. Analyze the following statement: "Malware is designed to improve the performance of a computing system." Is this statement true or false, and why?

• True, because malware enhances system operation
• True, because malware strengthens network security
• False, because malware is intended to damage a computing system or take partial control over its operation
• False, because malware is designed to provide unauthorized access to secure networks

3. Evaluate the effectiveness of phishing as a method for obtaining personal information. Which factor contributes most to its success?

• The victim's lack of technical knowledge
• The attacker's ability to create convincing fake websites or emails
• The ability of the attacker to bypass security measures
• The victim's willingness to share personal information

4. Compare multi-factor authentication with single-factor authentication in terms of security. What advantage does multi-factor authentication offer?

• Increased encryption strength
• Improved network accessibility
• Enhanced security by adding multiple layers of protection
• Faster decryption

5. In the context of public key encryption, explain the role of the receiver's private key.

• Encrypting the original message
• Decrypting the message sent by the sender
• Encrypting the message sent by the sender
• Sharing the public key with the sender

6. How does keylogging enable unauthorized access to confidential information?

• By causing damage to a computing system
• By providing unauthorized access to secure networks
• By recording user keystrokes to obtain passwords and other sensitive data
• By tricking users into providing personal information

7. What is the primary rationale behind using encryption to secure sensitive information?

• To make information accessible to unauthorized parties
• To damage a computing system
• To keep messages secret so that only authorized parties can read them
• To trick users into providing personal information

8. Why is protecting Personally Identifiable Information (PII) crucial in maintaining individual privacy?

• Because it can lead to unauthorized access to secure networks
• Because it is information that identifies, links, relates, or describes an individual
• Because it can be used to record keystrokes
• Because it can be used in phishing attacks

9. How can a rogue access point compromise the security of a network?

• By providing unauthorized access to secure networks
• By recording keystrokes
• By tricking users into providing personal information
• By damaging a computing system

10. Why is decryption an essential aspect of secure communication?

• To allow authorized parties to access the original message
• To strengthen encryption methods
• To provide multi-factor authentication
• To spread malware
