    Mitigation guidance
    • To mitigate potential denial of service, ensure that the BIND recursive resolver's configuration includes appropriate limits for `max-records-per-type` and `max-types-per-name` within the `named.conf` file. These settings help control resource consumption when encountering invalid DNSSEC records. A restart of the `named` service is required for any configuration changes to take effect.
