100-160 Question 47
Select 3A company is transferring sensitive customer data between its on-premises data center and a cloud storage service. Which encryption protocols should the company use to ensure the data remains secure while in transit?
- A
TLS (Transport Layer Security)
- B
IPsec (Internet Protocol Security)
- C
AES (Advanced Encryption Standard)
- D
SSL (Secure Sockets Layer)
- E
SHA-256 (Secure Hash Algorithm 256)
Show answer and explanation
Correct answers: A, B, D
Explanation
When transferring data between locations, such as from an on-premises data center to a cloud service, protecting data in transit is critical. Protocols like TLS, IPsec, and SSL ensure that data is encrypted and secure while being transferred over the network. AES and SHA-256 serve other purposes, such as encryption for data at rest or hashing for data integrity, and are not suitable for securing data in transit.
- A. Correct.
TLS (Transport Layer Security) is a widely used protocol for encrypting data in transit, ensuring secure communication over a network.
- B. Correct.
IPsec is a protocol suite for securing Internet Protocol (IP) communications by encrypting and authenticating data in transit.
- C. Incorrect.
AES is a symmetric encryption algorithm used for encrypting data at rest or in use, not specifically for securing data in transit.
- D. Correct.
SSL (Secure Sockets Layer) is an older protocol for encrypting data in transit. Although it has been largely replaced by TLS, it is still relevant in some legacy systems.
- E. Incorrect.
SHA-256 is a hashing algorithm used for data integrity and not for encryption of data in transit.
