Web Access Security
Server Access
Access to the SC300 web server can be disabled or set for secure access using Secure Sockets
Layer (SSL) protocol.
SSL is a protocol for transmitting encrypted data over the Internet. URLs that require an SSL
connection start with https: instead of http:. If the network is insecure, Eaton recommends that
you disable HTTP Access.
