What is one of the main security benefits of transport encryption?

Prevention of eavesdropping on communications
Improved data extraction speed
Reduction of bandwidth usage
Unified security protocols

The correct answer is: Prevention of eavesdropping on communications

Transport encryption primarily serves to protect the confidentiality of data in transit by ensuring that the information exchanged over networks is not easily accessible to unauthorized parties. By encrypting the data during transmission, transport encryption prevents eavesdroppers from intercepting and decoding sensitive information, such as login credentials or personal data. This is particularly critical in scenarios where unencrypted data could be accessed on unsecured networks, such as public Wi-Fi. While the other options may seem relevant in different contexts, they do not highlight the primary security benefit of transport encryption. Improved data extraction speed pertains more to the efficiency of data processing rather than the protection of data itself. Similarly, reduction of bandwidth usage does not directly relate to security but rather focuses on network performance. Unified security protocols refer to integrating multiple security measures rather than the specific application and benefit of transport encryption in safeguarding communications.
