CISSP – Information Systems Security Architecture Professional (ISSAP) — Question 94

Perfect World Inc., provides its sales managers access to the company's network from remote locations. The sales managers use laptops to connect to the network. For security purposes, the company's management wants the sales managers to log on to the network using smart cards over a remote connection.
Which of the following authentication protocols should be used to accomplish this?

Answer options

• A. Challenge Handshake Authentication Protocol (CHAP)
• B. Microsoft Challenge Handshake Authentication Protocol (MS-CHAP)
• C. Open Shortest Path First (OSPF)
• D. Extensible Authentication Protocol (EAP)

Correct answer: D

Explanation

The correct answer is D, Extensible Authentication Protocol (EAP), as it supports various authentication methods, including smart cards, making it suitable for secure remote access. Options A and B, CHAP and MS-CHAP, are less secure and do not support smart card authentication. Option C, OSPF, is a routing protocol and not an authentication method.
