What is the preferred method of protecting sensitive data in transit?

Utilizing encryption protocols is the preferred method of protecting sensitive data in transit because encryption effectively transforms data into a form that is unreadable without the appropriate decryption key. This means that even if the data is intercepted during transmission, malicious actors would not be able to interpret or utilize the information without the key. Encryption helps ensure the confidentiality and integrity of the data by making it secure from eavesdroppers and unauthorized access.

In the context of protecting data as it moves across networks, encryption protocols such as HTTPS, SSL/TLS, and IPsec are commonly used. These technologies create a secure tunnel through which data can travel safely, preventing unauthorized interception and alteration.

Other methods, such as the use of internal firewalls or implementing strong passwords, do enhance security but do not specifically address the challenge of protecting data during transmission. Regularly changing access permissions is crucial for maintaining control over who can access sensitive data, but it does not encrypt the data itself, leaving it vulnerable during transit. Therefore, encryption protocols are fundamental to safeguarding data in motion, making them the most effective option.
