    """<p>Creates a single DNS Firewall rule in the specified rule group. The rule can use any one of the following match sources, and the chosen source must be supplied through the matching request field — they are mutually exclusive:</p> <ul> <li> <p> <code>FirewallDomainListId</code> — match a customer-managed or Amazon Web Services-managed domain list.</p> </li> <li> <p> <code>DnsThreatProtection</code> — match a built-in DNS Firewall Advanced threat detector (<code>DGA</code>, <code>DNS_TUNNELING</code>, or <code>DICTIONARY_DGA</code>).</p> </li> <li> <p> <code>FirewallRuleType</code> — match one of the rule-type variants returned by <a>ListFirewallRuleTypes</a>: <code>FirewallAdvancedContentCategory</code>, <code>FirewallAdvancedThreatCategory</code>, <code>DnsThreatProtection</code>, or <code>PartnerThreatProtection</code>. The <code>PartnerThreatProtection</code> variant requires an active Amazon Web Services Marketplace subscription to the named partner product.</p> </li> </ul> <p>For rules that require asynchronous provisioning (today, the <code>PartnerThreatProtection</code> rule type), the rule's <code>Status</code> begins at <code>CREATING</code> and transitions to <code>COMPLETE</code> once the rule is provisioned and the marketplace entitlement is verified. If provisioning fails, <code>Status</code> becomes <code>CREATION_FAILED</code> and <code>StatusMessage</code> contains a human-readable reason; the rule is then immutable and must be removed with <a>DeleteFirewallRule</a>.</p>

    Args:
        creator_request_id: <p>A unique string that identifies the request and that allows you to retry failed requests without the risk of running the operation twice. <code>CreatorRequestId</code> can be any unique string, for example, a date/time stamp. </p>
        firewall_rule_group_id: <p>The unique identifier of the firewall rule group where you want to create the rule. </p>
        firewall_domain_list_id: <p>The ID of the domain list that you want to use in the rule. Can't be used together with <code>DnsThreatProtecton</code>.</p>
        priority: <p>The setting that determines the processing order of the rule in the rule group. DNS Firewall processes the rules in a rule group by order of priority, starting from the lowest setting.</p> <p>You must specify a unique priority for each rule in a rule group. To make it easier to insert rules later, leave space between the numbers, for example, use 100, 200, and so on. You can change the priority setting for the rules in a rule group at any time.</p>
        action: <p>The action that DNS Firewall should take on a DNS query when it matches one of the domains in the rule's domain list, or a threat in a DNS Firewall Advanced rule:</p> <ul> <li> <p> <code>ALLOW</code> - Permit the request to go through. Not available for DNS Firewall Advanced rules.</p> </li> <li> <p> <code>ALERT</code> - Permit the request and send metrics and logs to Cloud Watch.</p> </li> <li> <p> <code>BLOCK</code> - Disallow the request. This option requires additional details in the rule's <code>BlockResponse</code>. </p> </li> </ul>
        block_response: <p>The way that you want DNS Firewall to block the request, used with the rule action setting <code>BLOCK</code>. </p> <ul> <li> <p> <code>NODATA</code> - Respond indicating that the query was successful, but no response is available for it.</p> </li> <li> <p> <code>NXDOMAIN</code> - Respond indicating that the domain name that's in the query doesn't exist.</p> </li> <li> <p> <code>OVERRIDE</code> - Provide a custom override in the response. This option requires custom handling details in the rule's <code>BlockOverride*</code> settings. </p> </li> </ul> <p>This setting is required if the rule action setting is <code>BLOCK</code>.</p>
        block_override_domain: <p>The custom DNS record to send back in response to the query. Used for the rule action <code>BLOCK</code> with a <code>BlockResponse</code> setting of <code>OVERRIDE</code>.</p> <p>This setting is required if the <code>BlockResponse</code> setting is <code>OVERRIDE</code>.</p>
        block_override_dns_type: <p>The DNS record's type. This determines the format of the record value that you provided in <code>BlockOverrideDomain</code>. Used for the rule action <code>BLOCK</code> with a <code>BlockResponse</code> setting of <code>OVERRIDE</code>.</p> <p>This setting is required if the <code>BlockResponse</code> setting is <code>OVERRIDE</code>.</p>
        block_override_ttl: <p>The recommended amount of time, in seconds, for the DNS resolver or web browser to cache the provided override record. Used for the rule action <code>BLOCK</code> with a <code>BlockResponse</code> setting of <code>OVERRIDE</code>.</p> <p>This setting is required if the <code>BlockResponse</code> setting is <code>OVERRIDE</code>.</p>
        name: <p>A name that lets you identify the rule in the rule group.</p>
        firewall_domain_redirection_action: <p> How you want the the rule to evaluate DNS redirection in the DNS redirection chain, such as CNAME or DNAME. </p> <p> <code>INSPECT_REDIRECTION_DOMAIN</code>: (Default) inspects all domains in the redirection chain. The individual domains in the redirection chain must be added to the domain list.</p> <p> <code>TRUST_REDIRECTION_DOMAIN</code>: Inspects only the first domain in the redirection chain. You don't need to add the subsequent domains in the domain in the redirection list to the domain list.</p>
        qtype: <p> The DNS query type you want the rule to evaluate. Allowed values are; </p> <ul> <li> <p> A: Returns an IPv4 address.</p> </li> <li> <p>AAAA: Returns an Ipv6 address.</p> </li> <li> <p>CAA: Restricts CAs that can create SSL/TLS certifications for the domain.</p> </li> <li> <p>CNAME: Returns another domain name.</p> </li> <li> <p>DS: Record that identifies the DNSSEC signing key of a delegated zone.</p> </li> <li> <p>MX: Specifies mail servers.</p> </li> <li> <p>NAPTR: Regular-expression-based rewriting of domain names.</p> </li> <li> <p>NS: Authoritative name servers.</p> </li> <li> <p>PTR: Maps an IP address to a domain name.</p> </li> <li> <p>SOA: Start of authority record for the zone.</p> </li> <li> <p>SPF: Lists the servers authorized to send emails from a domain.</p> </li> <li> <p>SRV: Application specific values that identify servers.</p> </li> <li> <p>TXT: Verifies email senders and application-specific values.</p> </li> <li> <p>A query type you define by using the DNS type ID, for example 28 for AAAA. The values must be defined as TYPENUMBER, where the NUMBER can be 1-65534, for example, TYPE28. For more information, see <a href="https://en.wikipedia.org/wiki/List_of_DNS_record_types">List of DNS record types</a>.</p> </li> </ul>
        dns_threat_protection: <p> The type of the DNS Firewall Advanced rule. This setting is mutually exclusive with <code>FirewallDomainListId</code> and <code>FirewallRuleType</code>. Valid values are: </p> <ul> <li> <p> <code>DGA</code>: Domain generation algorithms detection. DGAs are used by attackers to generate a large number of domains to launch malware attacks.</p> </li> <li> <p> <code>DNS_TUNNELING</code>: DNS tunneling detection. DNS tunneling is used by attackers to exfiltrate data from the client by using the DNS tunnel without making a network connection to the client.</p> </li> <li> <p> <code>DICTIONARY_DGA</code>: Dictionary-based domain generation algorithms detection. Dictionary DGAs use wordlists to generate domains that appear more legitimate, making them harder to detect than traditional DGAs.</p> </li> </ul>
        confidence_threshold: <p> The confidence threshold for DNS Firewall Advanced. You must provide this value when you create a DNS Firewall Advanced rule. The confidence level values mean: </p> <ul> <li> <p> <code>LOW</code>: Provides the highest detection rate for threats, but also increases false positives.</p> </li> <li> <p> <code>MEDIUM</code>: Provides a balance between detecting threats and false positives.</p> </li> <li> <p> <code>HIGH</code>: Detects only the most well corroborated threats with a low rate of false positives. </p> </li> </ul>
        firewall_rule_type: <p>The rule type configuration for the firewall rule. This is a tagged union — set exactly one of its members. This setting is mutually exclusive with the top-level <code>FirewallDomainListId</code> and <code>DnsThreatProtection</code> fields. Use one of:</p> <ul> <li> <p> <code>FirewallAdvancedContentCategory</code> — match an Amazon Web Services-managed content category (for example, <code>VIOLENCE_AND_HATE_SPEECH</code>).</p> </li> <li> <p> <code>FirewallAdvancedThreatCategory</code> — match an Amazon Web Services-managed advanced threat category (for example, <code>PHISHING</code>).</p> </li> <li> <p> <code>DnsThreatProtection</code> — match a built-in DNS Firewall Advanced threat detector (<code>DGA</code>, <code>DNS_TUNNELING</code>, or <code>DICTIONARY_DGA</code>).</p> </li> <li> <p> <code>PartnerThreatProtection</code> — match a third-party threat feed delivered through Amazon Web Services Marketplace. The selected partner must be an active subscription on the calling account.</p> </li> </ul> <p>To enumerate the values supported in your account, call <a>ListFirewallRuleTypes</a>.</p>

    Raises:
