"workarounds": [
{
"lang": "en",
"value": "Users are recommended to take the following mitigation measures:\n\n * Enable the IP Filter feature: Configure and enable the PLC's built-in IP Filter function via the programming software. Restrict access exclusively to the IP addresses of trusted devices (such as designated HMI panels or SCADA hosts) to block unauthorized network access.\n\n * Set up PLC password protection: Enable password protection for the PLC within the programming software to ensure the device's core control logic and parameters cannot be easily downloaded, overwritten, or tampered with.\n\n * Implement network isolation and firewall protection: Deploy the PLC within an independent local area network (OT control network) secured by a firewall. Never connect the device directly to the office network or the Internet. If remote access is required, enforce the use of a secure, authorized VPN tunnel.",
