What is data encryption in transit?

• A. Encrypting data before storage on disk
• B. A process for encrypting data being transferred over a network
• C. Encrypting data before it is processed
• D. A method to restrict data access

Answer: (B)

Data encryption in transit refers specifically to the practice of encrypting data as it travels across a network. This ensures that data being transmitted—whether over the internet, through internal networks, or during communication between systems—remains confidential and secure from unauthorized access or interception. By applying encryption during transmission, sensitive information such as personal details, financial data, or proprietary business information is protected from eavesdroppers and cyber threats. Essentially, encryption in transit helps to maintain the integrity and privacy of data as it moves between its source and destination. Other options address different aspects of data management and security. For example, encrypting data before storage on disk pertains to securing data at rest, while encrypting data before it is processed refers to proactive data protection that happens before any use of the data occurs. The method to restrict data access does not directly involve encryption and is more about access controls and permissions within a system.
