'The following text was originally created by the Cybersecurity and Infrastructure Security Agency (CISA). The original
can be found at CISA.gov.

Mitsubishi Electric recommends that users take the following mitigation measures to minimize the risk:

- Use a firewall or virtual private network (VPN), etc. to prevent unauthorized access when Internet access is required.
- Use within a LAN and block access from untrusted networks and hosts through firewalls.
- Use IP filter function to block access from untrusted hosts. For details on the IP filter function, following manual
for each product; "12.1 IP Filter Function" in the MELSEC iQ-F FX5 User\'s Manual (Ethernet Communication), "1.13
Security" – "IP Filter" in the MELSEC iQ-R Ethernet User\'s Manual (Application).
- Restrict physical access to the affected products and the LAN that is connected by them.

For additional information refer to Mitsubishi Electric\'s security bulletin 2023-014_en.');
