Cybersecurity Concepts and Data Integrity

Which two main types of technologies are used to achieve confidentiality in cybersecurity?

• Access Control and Availability

• Integrity and Encryption

• Access Control and Encryption

• Authentication and Authorization

What is the primary purpose of authentication in cybersecurity?

• To ensure data is not modified.

• To verify the identity of a user.

• To encrypt data for secure transmission.

• To grant specific privileges to a user.

How does encryption contribute to confidentiality?

• It verifies the identity of the sender.

• It ensures data is not tampered with during transmission.

• It obscures data, making it unreadable to unauthorized parties.

• It grants access based on user roles.

What is the main goal of ensuring data integrity?

• To prevent unauthorized users from accessing data.

• To ensure that data is true to itself and any modifications are detectable.

• To guarantee continuous access to information.

• To verify user privileges before granting access.

Which of the following is a primary method for ensuring data integrity?

• Implementing strong passwords.

• Using encryption to hide data.

• Applying digital signatures or hashing.

• Distributing data across multiple servers.

What type of cyberattack involves overwhelming a target system with traffic from numerous compromised computer systems to disrupt its normal functioning?

• Phishing attack

• Distributed Denial of Service (DDoS) attack

• Man-in-the-middle attack

• SQL injection attack

How does a SYN flood attack typically render a server unavailable?

• By injecting malicious code into the server's database.

• By sending an excessive number of incomplete connection requests, exhausting server resources.

• By tricking users into revealing their login credentials.

• By encrypting the server's files and demanding a ransom.
