SSL VPN For M2M Gateway
• Technology : Secure Sockets Layer virtual private network (SSL VPN) is a kind of VPN that runs on Secure Socket Layers technology and is accessible via https over web browsers. It permits users to establish safe and secure remote access sessions from virtually any Internet connected browser. SSL functions between the Transmission Control Protocol ( TCP) l ayer and appl i c a t ion l ayer protocols. Traditional VPN requires the installation
of IPsec client software on a client machine before a connection is established whereas SSL VPN has no such requirement. Corporate users are able to access confidential applications or shared files on standard web browsers.
• Security Benefit : The main benefit of SSL VPN technology is that since it is user-based, not device-based, any authorized user can login from web-enabled PCs for secure, remote access of confidential files. The safety issues are similar to SSL-based credit card online transactions.
