A SSL VPN is a form of secure virtual private network that can be used with a web browser. SSL means Secure socket layer. Unlike the Internet protocol security VPN, a SSL VPN doesn’t require any client software to be installed on the end user system. It is mainly used to provide access to the remote users with web applications, internal network connections and server-client applications.
VPN (virtual private network) allows for secure communication mechanism for any information or data to be transmitted between the two remote computers. SSL VPN has few or more VPN devices to which an user connects with the help of a browser. The traffic between the SSL VPN and the web browser is encrypted using SSL protocol or with TLS (Transport layer security) protocol.
SSL VPN is a type of VPN which uses secure socket layers technology which can be accessed via https in web browsers. Users are allowed to establish remote sessions which is secure with any internet connected web browser virtually. Here, users can access confidential applications, shared files on web browsers. The main use of SSL VPN technology is not being device based but being an user-based by which an authorized user can log in from web browsers remotely with secure access to the files.
A SSL VPN is easy to use and offers versatility in controlling the range of the users on various computers who are accessing the data/resources from different locations.
SSN delivers the following modes of SSL VPN access through a web based interface.
CLIENT LESS MODE:
Client less mode provides secure access to the private web resources. This mode is useful if you expect to access in the web browser such as internet, databases, online tools, etc.
THIN CLIENT MODE:
Thin client mode expands the capability of cryptography functions of a web browser to enable the remote access such as POP3 (post office protocol version), Secure shell, SMTP (simple mail transfer protocol), IMAP, etc.
Full tunnel client mode offers extensive application support through next generation SSL VPN client for SSL VPN. It offers light weight, easy to support SSL VPN tunneling client providing network layer.
Types of SSL VPN’s:
SSL PORTAL VPN:
This SSL VPN allows only for a single SSL connection to the user so that he can access multiple network services securely. The website is called portal since it is the single door that leads to many other resources. The remote end user accesses the SSL VPN gateway using a web browser which identifies the user with authentication method and displays a web page which acts as a portal for many other network services.
SSL TUNNEL VPN:
SSL tunnel VPN allows a browser to access multiple network services securely through a tunnel including all the applications and protocols that are not associated with web. This tunnel runs under SSL security.These tunnels are to make web browsers to handle active content like java, java script, flash applications, etc.
Thus, virtual private network with SSL encryption …
