    Mitigation guidance
    • To mitigate this issue, restrict access to the BIND service to trusted clients only, or disable DNS-over-HTTPS if it is not required. To restrict network access to the BIND service, configure firewall rules to only allow connections from trusted IP ranges to port 53 (UDP and TCP). For example, using `firewalld`: `firewall-cmd --permanent --add-rich-rule='rule family="ipv4" source address="<TRUSTED_IP_RANGE>" port port="53" protocol="udp" accept'` `firewall-cmd --permanent --add-rich-rule='rule family="ipv4" source address="<TRUSTED_IP_RANGE>" port port="53" protocol="tcp" accept'` `firewall-cmd --reload` If DNS-over-HTTPS is enabled and not essential, consider disabling it in the BIND configuration. Refer to the BIND administrator's reference manual for instructions on disabling DNS-over-HTTPS. Changes to BIND configuration require a restart of the `named` service for them to take effect.
