Protecting the Network
94LS-07W
Connecting the machine to a network allows you link it to computers and mobile devices for more convenient
operations. However, this also creates risks of unauthorized access and eavesdropping over the network.
By configuring the security settings according to your network environment, you can reduce these risks to ensure
safer use of the machine.
Filtering Using the Firewall Settings
Allows communications only with devices that have a specific IP address or MAC address to prevent
unauthorized access.
Port Control
If the port number being used by a communicating device, such as a computer or server, is changed, change
the setting on the machine too. In addition, if it is clear that there is an unneeded protocol, use of the
protocol is prohibited on the machine and that port is closed to prevent intrusion from the outside.
Changing the Port Number(P. 308)
Using a Proxy Server
Using a proxy server to connect the machine to a network not only facilitates managing communication with
external networks but blocks unauthorized access and consolidates anti-virus protection for enhanced
security.
Encryption of Communication Using TLS
You can use TLS to encrypt communication when using Remote UI. This reduces the risks of data
eavesdropping and tampering during communication.
Using the Machine in a Network with IEEE 802.1X Authentication
When connecting the machine to a network that uses IEEE 802.1X authentication, you must configure the
settings on the machine such as the authentication method managed by the authentication server.
Managing and Verifying the Key and Certificate
You can generate a key and certificate used to encrypt communication and register a key and certificate
obtained from a certification authority. By configuring the settings to check the revocation status of a
certificate (using OCSP), you can check to see if a certificate received from a certification authority has been
revoked.
