Question
Which of the following is true about tunneling and encryption?
Options
- ASIP encrypts all data going through the tunnel.
- BPPTP creates a secure tunnel.
- CSSL VPN provides a secure tunnel.
- DRAS is a secure way to create a tunnel.
Explanation
SSL VPN is the correct answer because it uses SSL/TLS to provide both an encrypted tunnel and strong authentication, making it genuinely secure.
Common mistakes.
- A. SIP (Session Initiation Protocol) is a signaling protocol used to initiate and manage VoIP and multimedia sessions - it does not itself encrypt tunnel data.
- B. PPTP (Point-to-Point Tunneling Protocol) creates a VPN tunnel but relies on MPPE for encryption, which has known security flaws including weak key negotiation, and is widely considered insecure.
- D. RAS (Remote Access Service) is a Windows platform feature that enables remote connectivity but does not by itself create an encrypted secure tunnel - security depends entirely on which protocol is configured on top of it.
