6 1 Introduction 1. Introduction About the Product This manual describes how to install the Linux OS on our industrial computer products and provides information about the operational check results as well as the minimum configuration and packages required to run the Linux OS. Refer to it when building your system. Make sure you understand and agree with the cautions below before using this manual. Refer to the User s Manual for our industrial computer products specifications. Caution on the BX-320 Series CAUTION - The content of this manual is consistent with the results of operational checks conducted in our testing environment and does not guarantee proper operations of the Linux OS itself on our products. - Make sure you thoroughly conduct operational checks when using the content of this manual. - CONTEC shall not be held liable for damages suffered by you due to the installation or use of the Linux OS based on the content of this manual. - Please note that we do not accept any questions regarding the Linux OS in general, including about Linux-related content described in this manual. - Results may differ from the content of this manual if the Linux OS is customized or if changes are made to the BIOS.

7 1 Introduction 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. [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. [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. - 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. 2 BX-320 RedHat Enterprise Linux bit Operational Check Manual
