Technical Overview

zGateway is an application gateway solution providing secure remote access to applications and private network resources through secure TLS connection, enabling policy based access, AAA, confidentiality and integrity of data.

WHAT IS SSL/TLS? The Secure Socket Layer protocol was created by Netscape to ensure secure transactions between web servers and browsers. The protocol uses a third party, a Certificate Authority (CA). SSL uses a cryptographic system that uses two keys to encrypt data − a public key known to everyone and a private or secret key known only to the recipient of the message. SSL technology is embedded in all popular browsers and engages automatically when the user connects to a web server that is SSL-enabled. When your browser connects to an SSL server, it automatically asks the server for a digital Certificate of Authority (CA). This digital certificate positively authenticates the server’s identity to ensure you will not be sending sensitive data to a hacker or imposter site. The browser also makes sure that the domain name matches the name on the CA, and that the CA has been generated by a trusted authority and bears a valid digital signature. Once the handshake is completed, your browser will automatically encrypt all information that you send to the site, before it leaves your computer.
