Information Security Quiz

Explain the concept of public key infrastructure (PKI).

• A framework that uses cryptographic keys to secure communications and authenticate identities

• A method of encrypting data to protect it from unauthorized access

• A process of modifying data to ensure its integrity

• A technique for intercepting data during transmission

How can digital signatures be used to verify authenticity?

• By encrypting data to protect it from unauthorized access

• By converting data into an unreadable format

• By using cryptographic techniques to verify the source and integrity of data

• By modifying data to ensure its accuracy

What is information fabrication, and how can it impact data integrity?

• The creation of false data, which can introduce incorrect information into a system

• The encryption of data, which can protect it from unauthorized access

• The modification of data, which can ensure its accuracy

• The interruption of data transmission, which can prevent data from reaching its destination

What is the definition of authority in the context of information security?

• The ability to modify data

• The right to access and control information

• The process of encrypting data

• The method of verifying data integrity

What are the common methods used for encryption?

• Symmetric encryption and asymmetric encryption

• Data fabrication and data modification

• Data interruption and data interception

• Digital signatures and public key infrastructure

What are the potential consequences of information interception?

• Unauthorized access to sensitive data and privacy breaches

• Ensuring data integrity and authenticity

• Encrypting data to protect it from unauthorized access

• Modifying data to ensure its accuracy

What is the difference between interruption and interception in the context of data transmission?

• Interruption involves unauthorized access to data, while interception disrupts data transmission

• Interruption disrupts data transmission, while interception involves unauthorized access to data

• Interruption ensures data integrity, while interception ensures data authenticity

• Interruption encrypts data, while interception decrypts data

What is the primary purpose of encryption?

• To delete sensitive information

• To convert data into an unreadable format

• To verify the authenticity of data

• To modify data during transmission

Explain the concept of a man-in-the-middle attack.

• An attacker intercepts and potentially alters communication between two parties

• Data is encrypted to protect it from unauthorized access

• Data is modified to ensure its integrity

• A digital signature is used to verify the authenticity of data

How can encryption protect sensitive information during transmission?

• By converting data into an unreadable format

• By modifying data to ensure its accuracy

• By intercepting data during transmission

• By fabricating data to introduce false information
