SSL:
SSL (Secure Sockets Layer) is the standard security technology used to establish an encrypted link between a web server and a browser. This link ensures that all data passed between the web server and browsers remain private and integral.
In PointCentral®, an encrypted link is established between the Point® client and the PointCentral Web Service that runs on the server where PointCentral is installed.
Encryption Protocols:
PointCentral does not dictate the security protocols used on the client and server devices.
PointCentral requires the use of an SSL Certificate. This certificate is used to validate that the connections from the client that runs Point are reaching the expected PointCentral server.
The authentication and encryption protocols used are negotiated by the client and server based on what is available.
If you disable the unwanted protocols on both ends, Point should continue to connect and communicate with the PointCentral server without any issues as long as the two systems have at least one mutually agreeable protocol (SSL 3.0, 3.1,TLS 1.2, etc.).
Supported Protocols:
IIS web server uses a minimum of TLS 1.2.
