IPsec VPN traffic is secured in two stages: For information on Dell SonicWALL SSL VPN appliances, see the Dell SonicWALL Website: Note Dell SonicWALL makes SSL VPN devices that you can use in concert with or independently of a Dell SonicWALL network security appliance running SonicOS. No special VPN client software or hardware is required. One advantage of SSL VPN is that SSL is built into most Web Browsers.

An SSL VPN uses SSL to secure the VPN tunnel. SSL uses the public-and-private key encryption system from RSA, which also includes the use of a digital certificate. SSL uses a program layer located between the Internet's Hypertext Transfer Protocol (HTTP) and Transport Control Protocol (TCP) layers.

SSL VPN: Secure Socket Layer (SSL) is a protocol for managing the security of a message transmission on the Internet, usually by HTTPS.

The specific information associated with each of these services is inserted into the packet in a header that follows the IP packet header. IPsec provides two choices of security service: Authentication Header (AH), which essentially allows authentication of the sender of data, and Encapsulating Security Payload (ESP), which supports both authentication of the sender and encryption of data as well. SonicOS supports the creation and management of IPsec VPNs. An advantage of IPsec is that security arrangements can be handled without requiring changes to individual user computers.

IPsec VPN: IPsec is a set of protocols for security at the packet processing layer of network communication.

There are two main types of VPN in popular use today: It is also far less costly, because it uses the existing Internet infrastructure. Because this tunnel is not a physical connection, it is more flexible-you can change it at any time to add more nodes, change the nodes, or remove it altogether.

This was both inflexible and expensive.Ī VPN creates a connection with similar reliability and security by establishing a secure tunnel through the Internet. Prior to the invention of Internet Protocol Security (IPsec) and Secure Socket Layer (SSL), secure connections between remote computers or networks required a dedicated line or satellite link. It provides security to protect the information from viewing or tampering en route. It provides authentication to ensure that the information is going to and from the correct parties.
