Mitsubishi Electric recommends users take the following mitigation measures to minimize the risk of exploitation of
these vulnerabilities:

- When communicating via untrusted networks or hosts, encrypt the communication path by setting up a VPN.

- Use firewalls or IP filter function to restrict connections to the products and prevent access from untrusted networks
or hosts. For details on IP filter function, refer to the following product manual:
    - “12.1 IP Filter Function” in the MELSEC iQ-F FX 5 User’s Manual (Ethernet Communication)
    - "IP filter" of "1.13 Security" in the MELSEC iQ-R Ethernet User\'s Manual (Application)
    - "IP Filter Function" of "6.2 Security Function" in the MELSEC iQ-R Motion Controller Programming Manual (Common)
    - "IP filter" of "1.4 Security" in the MELSEC iQ-R CC-Link IE TSN User\'s Manual (Application)
    - "IP filter" of "9.5 Security" in the MELSEC iQ-R CC-Link IE TSN Plus Master/Local Module User’s Manual
    - "14.3 IP Filter Function" in the Q Corresponding Ethernet Interface Module User\'s Manual (Basic)
    - "14.3 IP Filter Function" in the MELSEC-L Ethernet Interface Module User\'s Manual (Basic)
