Which is more secure, PPTP or OpenVPN?

If we talk about security, PPTP is far from secure. It is also the last VPN protocol you would want to use to stay safe online. IKEv2 and L2TP are more secure because they encapsulate your data twice. OpenVPN is the most secure VPN protocol.

What is a VPN Protocol?

What are the different authentication mechanisms?

The different authentication mechanisms that may be used with remote access services are: 1 PAP. Password Authentication Protocol. Passwords are sent in clear text so PAP is rarely used today. 2 CHAP. Challenge Handshake Authentication Protocol. CHAP uses a handshake process where the server challenges the client. The client then responds with appropriate authentication information. 3 MS-CHAP. Microsoft’s implementation of CHAP, which is used only by Microsoft clients. 4 MS-CHAPv2. An improvement over MS-CHAP. A significant improvement of MS-CHAPv2 over MS-CHAP is the ability to perform mutual authentication. 5 RADIUS. Remote Authentication Dial-In User Service. Radius provides a centralized method of authentication for multiple remote access services servers. RADIUS encrypts the password packets, but not the entire authentication process. 6 TACACS and XTACACS. Terminal Access Controller Access-Control System (TACACS) is a remote authentication protocol that was commonly used in UNIX networks. Extended TACACS (XTACACS) is an improvement over TACACS developed by Cisco Systems and is proprietary to Cisco systems. Neither of these are commonly used today with most organizations using either RADIUS or TACACS+. 7 TACACS+. Terminal Access Controller Access-Control System+ (TACACS) is an alternative to RADIUS and is proprietary to Cisco systems. A benefit of TACACS+ is that it can interact with Kerberos allowing it to work with a broader range of environments including Microsoft. Additionally, TACACS+ encrypts the entire authentication process (RADIUS encrypts only the password).
