Which term denotes a security protocol that uses certificates for authentication and encryption to protect web communications and other application protocols?

• A. Cipher suite
• B. PANs
• C. GPS
• D. Transport Layer Security (TLS)

Answer: (D)

Transport Layer Security (TLS) is the protocol that provides authentication and encryption for data in transit. It uses certificates issued by trusted authorities to verify identities and establish a secure, encrypted channel between clients and servers, protecting web traffic (like HTTPS) and other application communications. The process includes a handshake that negotiates algorithms and a session key, allowing confidentiality and integrity of the transmitted data. While a cipher suite defines the specific algorithms used during TLS, TLS itself is the protocol that enables certificate-based authentication and encryption. The other terms refer to unrelated concepts: a cipher suite is just a set of algorithms; PANs are Personal Area Networks; GPS is a satellite navigation system.
