What type of encryption is used to protect data in transit while it is being moved across systems?

TLS (Transport Layer Security) is the correct choice for protecting data in transit as it provides security measures to encrypt communications over computer networks. TLS works by encrypting data as it is transferred between systems, ensuring that any sensitive information remains confidential and secure from interception during transmission. This is crucial for a variety of internet communications, including web browsing, email, and virtual private networks (VPNs), as it helps to authenticate the communicating parties and maintain the integrity of the data being exchanged.

BitLocker, on the other hand, is a full disk encryption feature designed to protect data at rest on physical disks rather than during transmission. Software Guard Extensions (SGX) is a set of security-related software extensions that provide application-level security, primarily protecting code and data in memory, but it does not specifically address data in transit. AES is a symmetric encryption standard used for encrypting data but does not inherently facilitate the transmission security on its own; it is often utilized within protocols like TLS to secure data. Thus, TLS stands out as the most appropriate technology for safeguarding data while it travels across networks.
