100-160 Question 37
Single answerA company is implementing an encrypted communication channel between its remote employees and the office network. The IT team must ensure that data transmitted over the internet is securely encrypted to prevent eavesdropping. Which encryption method is the most appropriate for this scenario?
- A
Symmetric encryption using a shared secret key
- B
Asymmetric encryption using public and private keys
- C
Hashing to verify data integrity
- D
Transport Layer Security (TLS) protocol
Show answer and explanation
Correct answer: D
Explanation
The TLS protocol is widely used for securing communication over the internet, such as in HTTPS connections. It uses a combination of asymmetric encryption for key exchange and symmetric encryption for data transmission. This ensures that the transmitted data is encrypted, authenticated, and protected against tampering, making it the most appropriate solution for the given scenario.
- A. Incorrect.
Symmetric encryption is fast and efficient but requires both parties to share the same secret key securely, which makes it less suitable for securely establishing communication over the internet.
- B. Incorrect.
Asymmetric encryption is commonly used for secure key exchange, but it is not efficient for encrypting large amounts of data transmitted over the internet.
- C. Incorrect.
Hashing is used to ensure data integrity but does not encrypt data for confidentiality during transmission.
- D. Correct.
Transport Layer Security (TLS) is specifically designed for secure communication over the internet, providing encryption, authentication, and data integrity.
