Question

Which security feature fully encrypts code and data as it passes to the servers and only decrypts below the hypervisor layer?

Options

AFile-system level encryption
BTransport Layer Security (TLS)
CKey management service
DTrusted execution environments

Explanation

A trusted execution environment (TEE) is a security feature that fully encrypts code and data as it passes to the servers and only decrypts below the hypervisor layer. A TEE is a secure area of the main processor that provides isolation and protection for sensitive code and data from the rest of the system. A TEE can prevent unauthorized access, modification, or leakage of the code and data, even if the operating system, applications, or hypervisor are compromised. A TEE can also provide secure storage, secure boot, remote attestation, and cryptographic operations.
