Implementing Robust Security Features

Authorized users may incur unanticipated losses from attacks by malicious third parties, such as sniffing, spoofing,
and tampering of data as it flows over a network. To protect your important and valuable information from these
attacks, the machine supports the following features to enhance security and secrecy.
TLS Encrypted Communication
TLS is a protocol for encryption for data sent over a network and is often used for communication via a Web
browser or an e-mail application. TLS enables secure network communication when you access the machine
from a computer via the Remote UI.
IEEE 802.1X Authentication
IEEE 802.1X is a standard and mechanism for blocking unauthorized access to the network by collectively
managing user authentication information. If a device tries to connect to the 802.1X network, the device must
go through user authentication in order to prove that the connection is made by an authorized user.
Authentication information is sent to and checked by a RADIUS server, which permits or rejects communication
to the network depending on the authentication result. If authentication fails, a LAN switch (or an access point)
blocks access from the outside of the network. The machine can connect to an 802.1X network as a client
device. Configuring IEEE 802.1X Authentication(P. 154)
● The IEEE 802.1X function is only enabled when connected to a wired LAN. If the machine is connected
to a wireless LAN, the function cannot be used.
