Protecting the Communication between the WebVisu and the Browser

If necessary, you can generate the certificate required for encryption (SSL/TSL) on the Security Screen of the Devices tab. To request a CA-signed certificate, you have the option of generating a CSR (Certificate Signing Request) and storing it on your computer. You will also be notified that it is recommended to work with a CSR instead of using a self-signed certificate for the web server.

For instructions on creating the certificate and configuring the HTTPS connection, see the corresponding section on the following help page: Using an encrypted HTTPS connection

You can extend the configuration of the web server in the CODESYS Control for <device> SL runtime system so that additional HTTP Security headers are generated for enabling additional security functions.

For instructions, see the corresponding section on the following help page: Enabling the web browser with a HTTP Security header
