An organization is implementing a flexible approach for remote authentication and has selected an extensible protocol that supports multiple credential types. They want strong mutual validation between endpoints. Which method provides the best outcome?
A challenge that verifies server credentials but does not involve a client certificate
A handshake that uses certificates on both the client and the authentication server
A key exchange that omits certificate-based checks
A credential process requiring a personal identification code but lacking verification of the server
Mutual certificate-based authentication ensures both the client and server confirm each other's identity, reducing the risk of impersonation and MITM attacks. This approach is foundational for secure remote access protocols like EAP-TLS. Alternatives that involve single-ended validation or omit identity verification weaken the trust model and introduce vulnerabilities.
