Which method is used to protect data in transit, including website traffic, remote access traffic, and data synchronized between cloud repositories?

The method used to protect data in transit is Internet Protocol Security (IPSec). This protocol suite is critical for securing Internet Protocol (IP) communications by authenticating and encrypting each IP packet in a communication session. IPSec is specifically designed to secure the data being transmitted over networks, which includes traffic such as website interactions, remote access sessions, and data synchronization between cloud services.

IPSec operates at the network layer, allowing it to provide end-to-end security for any data communication that uses the IP protocol. It employs various encryption and authentication methods to ensure confidentiality and integrity of the data. By establishing secure tunnels for communication, IPSec helps protect sensitive information from eavesdropping and tampering in transit, making it a robust choice for safeguarding network traffic.

Other methods mentioned do not specifically fulfill this role in the same way. For instance, BitLocker is a disk encryption program that protects data at rest rather than in transit, while AES serves as a symmetric encryption standard but does not specify how and where it is applied; it could be used in various contexts but does not inherently secure data in transit on its own. Software Guard Extensions (SGX) is designed to protect application code and data from disclosure or modification, focusing more on secure enclaves
