3.Security Warning
When connecting to the network, be aware of security-related problems. See the examples of
Security measures below and set up the product properly along with the network devices.
1. Information security risks
Unauthorized access from the outside through a network could cause the system halt, data
damage, or exposure to malware. *1
Invaded and used as a stepping stone, a device might attack the others through networks. (a
victim becomes an assailant)
Information might leak without realizing due to the connection to the network.
Secondary damages such as harmful rumors, liability in damages, social credibility fall, and
opportunity loss are expected led by the troubles described above.
*1: Malware (Malicious Software) is software that brings harm to a computer system and performs
unintended operations.
2. Security measures – e.g.
Do not keep using the default password. (Refer to the product manual for the password
setting).
Set a strong password.
Combined with upper and lowercase letters, and numbers so that it cannot be easily
analogized by others.
Change the password periodically.
Disable unnecessary network services and functions.
Restrict access to the network with network devices. *2
Restrict ports to be released on the network with network devices. *2
Create a closed network connection using such as dedicated network or VPN*3
*2: Inquire for setting procedure to manufacturers.
*3: VPN (Virtual Private Network) a secured network that wards off unauthorized access by
protecting the communication path with authentication and encryption.
Unfortunately, there are no perfect ways to avert unauthorized access or close a security hole
that are endlessly found day and night.
Please understand that risks are always involved with the Internet connection, and we strongly
recommend a user should constantly update information security measures.
