Azure Key Vault uses Transport Layer Security (TLS) for encrypting data in transit. TLS is a widely accepted protocol that ensures secure communication over a computer network. It operates between the transport layer and the application layer in the OSI model, providing a critical layer of encryption that protects data transmitted between clients and servers. By implementing TLS, Azure Key Vault ensures that sensitive data such as encryption keys and secrets are transmitted securely, minimizing the risk of interception by unauthorized parties. The use of TLS also includes authentication, ensuring that communication occurs between trusted parties. Other protocols listed, such as Secure Sockets Layer (SSL), are outdated and have been largely replaced by TLS, which offers enhanced security features. Presentation Layer Security is not a recognized standard protocol for secure data transmission, and Internet Protocol Security (IPsec) is primarily used for securing network connections at the IP layer rather than at the application layer, making them less relevant in the context of Azure Key Vault’s operations.
