IPSec operates in two modes: Transport mode and Tunnel mode. You use transport mode for host-to-host communications. In transport mode, the data portion of the IP packet is encrypted, but the IP header is not. The security header is placed between the IP header and the IP payload.
PPTP. PointtoPoint Tunneling Protocol is one of the oldest VPN protocols in existence.
L2TP/IPSec. Layer 2 Tunnel Protocol is a replacement of the PPTP VPN protocol.
OpenVPN. OpenVPN is an open source protocol that allows developers access to its underlying code.
Which of the following is not an essential element of a VPN link? The Correct Answer is D. Explanation: Encryption is not necessary for the connection to be considered a VPN, but it is recommended for the protection of that data.
SSL VPNs provide remote users with access to Web applications and client/server applications, and connectivity to internal networks. Despite the popularity of SSL VPNs, they are not intended to replace Internet Protocol Security (IPsec) VPNs.
VPNs provide a way for authorized remote users to gain access to files, databases, and other network applications in a secure manner. Due to the inherent security risks of the Internet, companies providing remote access and telecommuting choices must protect their private data through a VPN.
The IPsec standards define two distinct modes of IPsec operation, transport mode and tunnel mode. The modes do not affect the encoding of packets. The packets are protected by AH, ESP, or both in each mode.
A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or individual users with secure access to their organization's network.
