General Security Recommendations for ORing Devices

To help reduce potential cybersecurity risks and strengthen the resilience of OT/IT network environments, ORing Industrial Networking Corp. recommends that users follow the security best practices below when deploying and operating ORing network devices.

Strengthen Network Access Control and Segmentation

• It is strongly recommended not to expose device communication ports directly to the public Internet.
• When configuring Access Control Lists (ACLs), adopt a “deny-by-default, allow-by-exception” policy, allowing only necessary communications.
• Utilize VLAN (Virtual Local Area Network) segmentation to isolate operational networks from other enterprise networks, preventing unauthorized cross-network access and limiting lateral movement.

Ensure Interface and Communication Security

• Disable unused network services and communication ports (such as Telnet or HTTP using plaintext protocols) to reduce the attack surface.
• For remote device management, always use secure encrypted protocols such as HTTPS, SSH, or SNMPv3 to ensure data confidentiality during transmission.
• If remote access from external networks is required, connections should be established through a secure VPN gateway, with access restricted to authorized sources.

Implement Proper Account and Authentication Management

• Before initial deployment, change all factory default passwords and enforce strong password policies.
• Follow the principle of least privilege by assigning dedicated accounts and appropriate role-based access control (RBAC) permissions for different users. Shared administrator accounts should be strictly prohibited.
• In centralized management environments, integrate external AAA servers such as RADIUS or TACACS+ for unified authentication and authorization.

Maintain System Updates and Firmware Management

• Regularly monitor announcements from ORing’s official channels and keep device firmware updated to the latest version to address known vulnerabilities and maintain system stability.
• Before performing major firmware upgrades or configuration changes, ensure that device configuration files are properly backed up to enable quick restoration in case of unexpected issues.

Enable Logging and Security Monitoring

• Enable system event and audit logging, and consider forwarding logs to a centralized Syslog server or SIEM platform for long-term storage and security monitoring.
• Ensure that devices synchronize time using NTP (Network Time Protocol) so that log timestamps remain accurate and consistent, facilitating effective security incident investigation.
