What is an example of a method used to protect data in motion, which describes the state when a system moves data?

Transport Layer Security (TLS) is widely recognized as a method used to protect data in motion. When data is transmitted over the internet or within networks, there is a significant risk of interception and eavesdropping. TLS addresses these security concerns by providing a protocol that encrypts the data during transit, ensuring that it remains confidential and intact as it travels from one point to another.

TLS not only encrypts the data but also facilitates authentication and integrity checking, which means it verifies the identities of the communicating parties and ensures that the data has not been altered in transit. This comprehensive approach is crucial for secure online communications, such as those used in web browsing, email, and other applications that rely on the transmission of sensitive information.

While BitLocker, IPSec, and Software Guard Extensions (SGX) serve important security purposes, they focus on different aspects of data protection. BitLocker is primarily a solution for encrypting data at rest on disk drives. IPSec, on the other hand, is used to secure Internet Protocol communications by authenticating and encrypting each IP packet of a communication session, which also relates to data in transit but in a different context than TLS, as it generally operates at the network layer.
