How SSL VPNs Work

[Langward]

Hi all,

SSL VPN with the current widely used industrial-grade Secure Sockets Layer SSL, without having to install client software, authorized users from any standard Web browser and Internet connection to securely access network resources, including PC, notebook computers and mobile devices, so safe and secure access to information. I want to know that how SSL VPNs Work. Any idea. Please reply. Thanks in advance.

SSL VPN to solve remote user access to sensitive corporate data to solve the simplest and most secure technology. IPSec VPN in comparison with the traditional, SSL VPN and more suitable for stand-alone client applications require access to a network of centers (such as mobile office), while the IPSec VPN is more suitable to build a secure channel between the two networks. check and reply.

In addition to the traditional sense of the remote connection to access other, government agencies and large enterprises to establish internal resource sharing in the enjoyment of efficient collaboration on the basis of results of the work or the Web uploading and downloading, while also facing to protect the internal network and its data security challenges, including network anti-virus, anti-intrusion, anti-hacking, data loss and so on. Here, based on the application of SSL VPN will be more and more. So they use SSL VPNs. Check and reply.

SSL VPN uses standard Secure Sockets Layer protocol for transmission of data packets are encrypted. SSL protocol is the browser that comes with the encryption strength is generally 128, from the application of the actual situation, fully able to meet the data transport layer security needs. In the authentication security, SSL VPN is becoming mature. The current use of multiple authentication mechanisms have become the mainstream, such as user name password checking, support for third-party PKI system, and can integrate with the CA Center for a digital certificate, USB KEY authentication, dynamic key to send text messages, have began a product of applications.

For intranet applications, security, SSL VPN in fact better than IPSec VPN. In terms of the standard IPSec VPN, and network security do not include further requirements, it just opens the path from the branch to headquarters for what is inside the transmission data is not effectively guaranteed. And therefore created a virus in the IPSec VPN within the inter-network communication and a series of security problems. The SSL VPN is different, it has always been based on application layer VPN. Only the application of open allowed to use, and does not give access to unrestricted access to the user. Therefore, from a security point of view to analyze, SSL VPN is fully capable to meet the security needs of mobile users access. All the best.

SSL VPN In addition to supporting Web application and can support any TCP-based applications (such as C / S application software), support for Windows Network Neighborhood, FTP and many other applications. Because technically speaking, as long as all the other non-Web applications to redirect the client to access all the data into the SSL protocol transmission, in the center-side recovery and restoration can be achieved.
