A Windows client administrator is implementing a solution for data in use. Which of the following represents security protection for data in use?

The correct choice focuses on a technology designed explicitly for protecting data in use, making it an appropriate solution for this scenario. Software Guard Extensions (SGX) is an Intel technology that creates a secure enclave in the memory of a computer, which isolates and protects sensitive information while it is being processed. This means that data remains secure from unauthorized access, even when it is actively being used by applications.

The secure enclaves created by SGX allow computing processes to execute in a protected environment, ensuring that data in use cannot be accessed or tampered with by other processes operating on the same system, including potential threats such as malware. This is particularly important for applications that handle sensitive information, such as financial data or personal identifiable information, where confidentiality needs to be maintained while the data is actively processed.

In contrast, the other options serve different purposes related to data transmission or storage protection, rather than specifically protecting data in use. For instance, TLS is primarily focused on securing data in transit, encrypting information exchanged over networks. BitLocker is a disk encryption tool that safeguards data at rest, while IPSec offers secure networking communication by encrypting data packets that travel over an IP network. Thus, they do not fit the requirement of directly securing data while it is
