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.
