ITF+ Data Encryption and Secure Disposal Basics

1. True or False: A private key should be shared with trusted parties to verify digital signatures.

True

False

2. Which organization sets standards for data encryption and secure disposal in the United States?

IEEE

NIST (National Institute of Standards and Technology)

ISO only

CompTIA exclusively

3. True or False: Encryption keys should be stored in the same location as encrypted data for convenience.

True

False

4. Which encryption protocol is considered the modern standard for securing web traffic?

SSL 2.0

TLS 1.2 or higher

HTTPS 1.0

WEP

5. What is the minimum recommended RSA key length for securing sensitive data today?

512 bits

1024 bits

2048 bits

4096 bits

6. Which of the following best describes crypto-shredding?

Physically destroying encrypted hard drives

Destroying encryption keys to render encrypted data inaccessible

Deleting files using specialized software

Overwriting data multiple times with random patterns

7. True or False: TLS (Transport Layer Security) uses only asymmetric encryption for all data transmission.

True

False

8. What is the relationship between encryption and data privacy?

Encryption guarantees complete privacy without other security measures

Encryption protects data confidentiality by making it unreadable to unauthorized parties

Encryption only works for data at rest, not in transit

Encryption and privacy are unrelated concepts

9. Which secure disposal method is most suitable for highly sensitive government data?

Soft delete

Physical destruction following NIST guidelines

Simple file overwriting

Formatting the storage device

10. What is the primary function of hashing in data security?

To encrypt sensitive data for storage

To create a unique fingerprint of data for integrity verification

To compress files for faster transmission

To replace passwords in authentication systems

11. Which encryption standard replaced DES and is widely used for symmetric encryption today?

AES (Advanced Encryption Standard)

RSA

Triple DES

Blowfish

12. What does NIST recommend as the minimum key length for AES encryption?

64 bits

128 bits

192 bits

256 bits

13. Which encryption method is best suited for encrypting large files due to its speed?

Asymmetric encryption

Symmetric encryption

Hash-based encryption

Quantum encryption

14. What is the purpose of a certificate authority (CA)?

To encrypt all internet traffic automatically

To issue, sign, and validate digital certificates

To generate encryption keys for users

To monitor network security breaches

15. Which of these is NOT a secure data disposal method?

Physical destruction of the storage device

Crypto-shredding (destroying encryption keys)

Deleting files and emptying the recycle bin

Degaussing magnetic media

16. What is a key advantage of end-to-end encryption?

It eliminates the need for firewalls

Data remains encrypted from sender to recipient, even in transit

It increases data transfer speed significantly

It prevents all types of cyberattacks

17. Which secure data disposal method uses a degausser?

Physical destruction by shredding

Wiping magnetic data from hard drives

Incinerating storage media

Formatting the drive multiple times

18. What does the acronym PKI stand for in the context of encryption?

Personal Key Infrastructure

Public Key Infrastructure

Private Key Interface

Protocol Key Implementation

19. Which of the following is a characteristic of asymmetric encryption?

Uses a single shared key for both encryption and decryption

Uses a pair of public and private keys

Faster than symmetric encryption for large files

Cannot be used for digital signatures

20. What is the primary purpose of a digital certificate in asymmetric encryption?

To verify the identity of the certificate holder and their public key

To encrypt data faster than symmetric encryption

To replace the need for passwords

To store private keys securely
