100-150 Question 270
Single answerA company has recently implemented a firewall to enhance its network security. During a routine check, the IT team notices that sensitive data is still being transmitted in plain text over the network. Which foundational security concept should they apply to address this issue?
- A
Confidentiality
- B
Integrity
- C
Availability
- D
Authentication
Show answer and explanation
Correct answer: A
Explanation
The issue of sensitive data being transmitted in plain text over the network is a breach of the confidentiality principle. Implementing encryption protocols, such as TLS, would ensure that data remains protected from unauthorized access during transmission, thereby addressing the confidentiality concern.
- A. Correct.
Confidentiality ensures that data is protected from unauthorized access and is encrypted to prevent interception or eavesdropping during transmission. This directly addresses the issue of sensitive data being transmitted in plain text.
- B. Incorrect.
Integrity refers to maintaining and assuring the accuracy and consistency of data over its lifecycle. While important, it does not address the issue of data being transmitted in plain text.
- C. Incorrect.
Availability ensures that systems and data are accessible to authorized users when needed. It is unrelated to the problem of encrypting sensitive data during transmission.
- D. Incorrect.
Authentication is the process of verifying the identity of users or systems. While critical for security, it does not solve the issue of protecting data in transit.
