Benefits and different types of SSL VPN

Secure Sockets Layer (SSL) is a common protocol for managing secure information transmission on the Internet. By using Web ssl vpn, clients securely log on to the enterprise network on other terminals without special authentication programs. This article describes the benefits and different types of ssl vpn.

Ssl vpn Protocol

Secure Sockets Layer (SSL) is a common protocol for managing secure information transmission on the Internet. Ssl vpn uses the local program layer between the HTTP and TCP layers of the Internet. It can be said that ssl vpn is part of Web browsers and most Web Server products. The term "intercept" refers to the method for intercept data between clients and server programs on the network or between program layers on the same host. SSL uses the Public and Private Key Encryption System in RSA, which also needs to be verified by digital certificates.

Ssl vpn works in SSL communication to ensure that access traffic may flow between all proxy servers or firewalls. Once the connection is successful, a small Java-based client will be downloaded to the computer Web browser, and a virtual connection will be created between your computer and the VPN hub or firewall server.

If necessary, Web ssl vpn will be automatically downloaded to the user's computer and can be installed automatically. When the end user session ends, the connection is automatically deleted from the computer to clear the use of the VPN Client. This means that clients using ssl vpn can log on to the company network from other computers without installing special authentication programs or other encryption systems. Users only need to know their own digital authentication and URL addresses connected to the Web ssl vpn hub.

SSL portal VPN

The SSL portal VPN allows you to create a single site-oriented SSL connection. End users can securely access multiple network services. This site is called a portal because it is on a single page) and can be connected to many other resources. Remote users can access the ssl vpn gateway through any modern Web browser. With the support of the gateway, the authentication method is used for identification, and then various web services can enter through this portal.

SSL tunnel VPN

Through a tunnel running at the underlying layer of SSL, this type of VPN allows Web browsers to securely access multiple network services, including applications and protocols that are not based on the Web. SSL tunnel VPN requires the Web browser to be able to process active content, so as to ensure that SSL tunnel VPN can provide functions not available in SSL portal VPN. Active Content includes Java, JavaScript, Active X, Flash application, or plug-in.

Benefits of ssl vpn in cloud security

Deploying the key part of the Wan (WANs)-the ssl vpn gateway-in the cloud is a leap for network engineers. However, the emergence of the cloud VPN service may be suitable for enterprises, however, the cost for global remote access infrastructure is too high.

The cloud VPN service is very suitable for Enterprises "the number of remote users is always fluctuating across regions worldwide, especially those regions that cannot achieve unified network access, and those regions that cannot be supported by a single ISP, "said Michael Suby, director of Frost & Sullivan. "When you cannot control Internet providers, you will be subject to various restrictions. Of course, this also depends on the various guarantees you can provide so far in terms of performance characteristics ."
