Secure communication for web services
We recommend to use the HTTPS secure protocol for the NK823x Web Server
[➙ 36] and the NK8000 Web Server tool. HTTPS adds an encryption layer (Secure
Sockets Layer or SSL) to the standard HTTP protocol and uses a certificate to
identify the website.
A self-signed Siemens certificate is automatically installed that can perfectly
support the secure communication, but causes the connecting browsers to display
one or more warnings indicating that the certificate is not issued by a trusted
certificate authority. To prevent such behavior:
Buy an SSL certificate to install on your server system. This is the common
security solution for the Internet websites. Several certificate authorities can
provide an SSL certificate for a moderate annual charge (in case of issues,
contact your local IT Manager or the Siemens customer support center).
Configure the browser of your client systems to trust the self-signed certificate.
This is a common technique for Intranet websites that are not available
publicly.
