Which version of CHAP is specifically developed by Microsoft?

1. RADIUS

2. PAP

3. MS-CHAP

4. Kerberos

The correct answer is: MS-CHAP

The version of CHAP that is specifically developed by Microsoft is MS-CHAP. This protocol was designed to provide a means of authenticating users in a secure manner, particularly in password authentication contexts, such as remote access to networks via Point-to-Point Protocol (PPP). MS-CHAP enhances the standard Challenge Handshake Authentication Protocol (CHAP) by adding features that allow for greater security and better integration within Microsoft operating systems. One of the key benefits of MS-CHAP is its support for Microsoft-specific functionalities, such as encrypted passwords and the ability to renew credentials without sending the user's password over the network. In contrast to other protocols listed, RADIUS (Remote Authentication Dial-In User Service) serves as a networking protocol providing centralized authentication, authorization, and accounting management for users accessing a network, but it does not specifically relate to CHAP. PAP (Password Authentication Protocol) is a much simpler protocol that transmits passwords in clear text, lacking the security structure provided by CHAP or its extensions. Kerberos is an authentication protocol designed for secure identity verification in a network and is fundamentally different from CHAP and its derivatives. Overall, MS-CHAP's design and functionality are specifically catered to Microsoft environments, making it the correct
