100-160 Question 48
Single answerA cybersecurity technician is tasked with ensuring the confidentiality of sensitive customer data as it is transmitted between a client application and a database server. Which protocol should they recommend to encrypt the transmission and protect the data in transit?
- A
HTTP
- B
FTP
- C
TLS
- D
Telnet
Show answer and explanation
Correct answer: C
Explanation
TLS (Transport Layer Security) is a widely used protocol to secure data in transit by encrypting it. Unlike protocols such as HTTP, FTP, or Telnet, which transmit data in clear text, TLS provides confidentiality and integrity, safeguarding sensitive customer information during transmission.
- A. Incorrect.
HTTP does not provide encryption and transmits data in plain text, making it vulnerable to interception.
- B. Incorrect.
FTP, like HTTP, lacks encryption by default and does not protect data in transit unless explicitly secured (e.g., FTPS or SFTP).
- C. Correct.
TLS (Transport Layer Security) is a protocol designed to encrypt data in transit, ensuring its confidentiality and integrity during transmission.
- D. Incorrect.
Telnet does not provide encryption, and all data, including sensitive information, is transmitted in plain text, making it insecure.
