AI-suggested
1. Network Segmentation: Isolate 70mai M300 devices on a dedicated VLAN or subnet with strict access controls to limit local network exposure. 2. Disable Telnet Service: If possible, disable the Telnet service on the device or restrict it to trusted management hosts only. 3. Monitor Network Traffic: Implement IDS/IPS solutions to detect unusual Telnet activity or repeated connection attempts to the device. 4. Access Control: Enforce strong network access policies to prevent unauthorized devices or users from connecting to the local network segment hosting the M300 devices. 5. Device Inventory and Firmware Management: Maintain an accurate inventory of 70mai M300 devices and monitor for firmware updates or vendor advisories despite the current lack of patches. 6. Incident Response Preparedness: Develop response plans for potential denial of service incidents affecting these devices, including fallback procedures for video recording and monitoring. 7. Vendor Engagement: Continue to seek vendor communication and encourage patch development or official mitigation guidance. 8. Alternative Solutions: Evaluate the use of alternative devices or vendors with better security track records if the risk is unacceptable.
