Cybersecurity Architecture: #2 ConfidentialityIntegrityAvailable

In cybersecurity, what does the acronym "CIA" stand for?

• Confidentiality, Integrity, Availability

• Central Intelligence Agency

• Computer Information Assurance

• Cybersecurity Incident Analysis

Which two main technologies are primarily used to achieve confidentiality?

• Access Control and Encryption

• Authentication and Authorization

• Multi-Factor Authentication and Role-Based Access

• Syslog and Blockchain

What two concepts are combined to form "Access Control" in the context of confidentiality?

• Multi-Factor Authentication and Role-Based Access

• Authentication and Authorization

• Encryption and Decryption

• Digital Signatures and Message Authentication Codes

What is the purpose of Multi-Factor Authentication (MFA) in ensuring confidentiality?

• To encrypt data during transmission

• To verify who a user claims to be

• To define what actions a user is allowed to perform

• To prevent unauthorized deletion of log records

If an authorized user passes both authentication and authorization checks, what is the outcome?

• Access is denied due to suspicious activity

• The user is allowed to proceed with their request

• The system initiates a SYN flood attack

• The user's data is immediately encrypted

What type of encryption is described when the same key is used for both encrypting and decrypting a message?

• Asymmetric encryption

• Public-key encryption

• Symmetric encryption

• Hashing encryption

What is the primary goal of ensuring integrity in cybersecurity?

• To prevent unauthorized access to data

• To ensure data is available to authorized users

• To ensure data is true to itself and detect modifications

• To encrypt communications between users

What happens if a bad actor gains superuser privileges and deletes log records from a syslog?

• The system automatically restores the deleted logs.

• The system's integrity is compromised, and the tampering might go unnoticed without additional measures.

• The bad actor is immediately locked out of the system.

• All user sessions are terminated to prevent further damage.

Which cryptographic functions are mentioned as ways to detect if a record has been tampered with?

• Multi-Factor Authentication and Role-Based Access

• Symmetric and Asymmetric Encryption

• Digital Signatures and Message Authentication Codes

• SYN and ACK packets
