What is a common method used to ensure data confidentiality in transit?

Explanation:
Ensuring data confidentiality in transit is crucial for protecting sensitive information from unauthorized access while it is being transmitted over networks. Encryption is a widely adopted method for achieving this security goal. When data is encrypted, it is transformed into a format that is unreadable to anyone who does not possess the correct decryption key or credentials. This means that even if an unauthorized entity intercepts the data as it travels across the network, they would be unable to understand or use the information because of its encrypted state. This provides a strong layer of protection against eavesdropping and data breaches during transmission. In contrast, while backups, access controls, and firewalls play important roles in data security, they serve different purposes. Backups are used for data recovery, access controls manage who can enter a system, and firewalls help in filtering traffic based on security rules. However, none of these methods specifically focus on the confidentiality of data during transmission, which is the primary concern addressed by encryption.
