For virtual private network (VPN) access to the corporate network, the information security manager is requiring strong authentication. Which of the following is the strongest method to ensure that logging onto the network is secure?
Correct Answer: D
Explanation/Reference: Explanation: Two-factor authentication requires more than one type of user authentication. While biometrics provides unique authentication, it is not strong by itself, unless a PIN or some other authentication factor is used with it. Biometric authentication by itself is also subject to replay attacks. A symmetric encryption method that uses the same secret key to encrypt and decrypt data is not a typical authentication mechanism for end users. This private key could still be compromised. SSL is the standard security technology for establishing an encrypted link between a web server and a browser. SSL is not an authentication mechanism. If SSL is used with a client certificate and a password, it would be a two-factor authentication.
