These systems maybe subject to a new threat, cyberattack. To protect the industrial IoT from cyberattacks, it is important to take multiple measures (multi-layer protection) for IoT devices, networks and clouds.For this purpose, SMC recommends that the following measures are always taken into consideration. For further details of the following measures, please see security information published by your local country security agencies.1. Do not connect the devices via a public network.• If you unavoidably need to access the device orcloud via a public network, ensure to use a secure,private network such as VPN.• Do not connect an office IT network and factory IoT network.2. Build a firewall to prevent a threat from entering the device and system.• Set up a ro uter or firewall at network boundaries toallow minimum required communications.• Disconnect from the network or turn off the device if no continuous connection is required.3. Physically block an access to unused communication ports or disable them.• I nspect regularly each port if any unnecessarydevice is connected to the network system.• Operate necessary services (SSH, FTP, SFTP, etc.) only.• Set a transmission range of the device using awireless LAN or other radio system to the minimumrequired and use only devices approved according to the radio act in the country concerned.• Install a device generating radio waves in such place as there is no interference from indoor or outdoor. 4. Set up a secure communication method such as data encryption.• Encrypt data in every environment, including IoTnetworks, secure gate-way connections, for securecommunications.5. Grant access permissions by user accounts and limit the number of users.• Regularly review accounts and delete all unusedaccounts or permissions.• Establish an account lockout system to block anaccess to the account for a certain period if log-infails more than the given threshold.6. Protect passwords.• Change the default password when you firstuse the device or system.• Choose a long password (minimum 8characters) using a mix of different letters and characters to make the password more secure and harder to hack.7. Use the latest security software.• Install antivirus software on all computers todetect and remove viruses.• Keep the antivirus software up to date.8. Use the latest version of the device and system software.• Apply patches to keep the OS and applications up to date.9.
