About Digital Certification
You can configure the following digital certificates for your network using Web Config:
CA-signed Certificate
You can ensure secure communications using a CA-signed certificate for each security feature. The
certificates must be signed by and obtained from a CA (Certificate Authority).
Self-signed Certificate
A self-signed certificate is issued and signed by the product itself. You can use the certificate for only
SSL/TLS communication, however security is unreliable and you may see a security alert in the
browser during use.
