How can you protect sensitive data in transit?

• A. By using firewalls and network segmentation
• B. By employing encryption protocols and secure communication channels
• C. By limiting the number of devices accessing the network
• D. By implementing password protection on sensitive files

Answer: (B)

Using encryption protocols and secure communication channels is vital for protecting sensitive data in transit because it ensures that the information being sent over networks is rendered unreadable to potential interceptors. When encryption is applied, even if the data packets are captured during transmission, they cannot be deciphered without the correct decryption keys. This protects confidentiality and maintains data integrity as the information travels from one point to another. Secure communication channels such as SSL/TLS for web traffic or VPNs for remote access create a protective layer around sensitive data. They not only encrypt the content but also help confirm the identity of the parties involved in the communication, ensuring that the data is being sent to and received by the correct endpoints. In contrast, while firewalls and network segmentation are essential for overall network security and can help limit exposure to threats, they do not specifically secure the actual data in transit. Limiting the number of devices accessing a network can help reduce vulnerability but does not address the protection of data that is actively being transmitted. Implementing password protection on sensitive files provides some level of security, but it often applies to data at rest rather than data being transferred, which is where encryption and secure channels become crucial.
