@Generated("software.amazon.awssdk:codegen") public final class RulesSourceList extends Object implements SdkPojo, Serializable, ToCopyableBuilder<RulesSourceList.Builder,RulesSourceList>

Stateful inspection criteria for a domain list rule group.

For HTTPS traffic, domain filtering is SNI-based. It uses the server name indicator extension of the TLS handshake.

By default, Network Firewall domain list inspection only includes traffic coming from the VPC where you deploy the firewall. To inspect traffic from IP addresses outside of the deployment VPC, you set the HOME_NET rule variable to include the CIDR range of the deployment VPC plus the other CIDR ranges. For more information, see RuleVariables in this guide and Stateful domain list rule groups in Network Firewall in the Network Firewall Developer Guide.

  • Method Details

    • hasTargets

      public final boolean hasTargets()
      For responses, this returns true if the service returned a value for the Targets property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
    • targets

      public final List<String> targets()

      The domains that you want to inspect for in your traffic flows. Valid domain specifications are the following:

      • Explicit names. For example, abc.example.com matches only the domain abc.example.com.

      • Names that use a domain wildcard, which you indicate with an initial '.'. For example, .example.com matches example.com and matches all subdomains of example.com , such as abc.example.com and www.example.com.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasTargets() method.

      Returns:

      • Explicit names. For example, abc.example.com matches only the domain abc.example.com.

    • targetTypes

      public final List<TargetType> targetTypes()

      The types of matching to perform against the domains in Targets. You can specify any combination of the following:

      • AWS_ROUTE_53_RESOLVED_DOMAIN – Match the domain against the domain that the Amazon Route 53 Resolver resolved the connection's destination IP address for.

      • HTTP_HOST – Match the domain against the Host header of HTTP traffic.

      • TLS_SNI – Match the domain against the Server Name Indication (SNI) of HTTPS traffic.

      AWS_ROUTE_53_RESOLVED_DOMAIN matches on how the destination IP address was resolved, rather than on the domain that the client asserts in its TLS SNI or HTTP Host header. This target type takes effect when you configure resolved IP validation on the firewall policy. For more information, see Route53ResolvedIPValidation.

      Whether you include AWS_ROUTE_53_RESOLVED_DOMAIN changes what the generated rules match, together with GeneratedRulesType:

      • Combining AWS_ROUTE_53_RESOLVED_DOMAIN with TLS_SNI or HTTP_HOST in an ALLOWLIST requires both conditions to match. The SNI or Host header must match the domain, and the Route 53 Resolver must have resolved the destination IP address for that domain. Network Firewall allows traffic only in that case. Traffic that matches one condition, such as a spoofed Host header sent to an unresolved IP address, is not allowed.

      • In a DENYLIST, or when AWS_ROUTE_53_RESOLVED_DOMAIN is the only target type, Network Firewall evaluates each condition independently: a match on either the domain (SNI or Host) or the resolved destination IP address triggers the rule.

      • When you don't include AWS_ROUTE_53_RESOLVED_DOMAIN, the generated rules match only on the SNI or Host header, without checking how the destination IP address was resolved.

      An ALLOWLIST whose only target type is AWS_ROUTE_53_RESOLVED_DOMAIN is additive: it allows matching traffic but doesn't generate a default rule that drops non-matching traffic. Only the TLS_SNI and HTTP_HOST target types generate that default drop. To allow only the resolved domains and drop all other traffic, include a protocol target type as well.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasTargetTypes() method.

    • generatedRulesType

      public final GeneratedRulesType generatedRulesType()

      Whether you want to apply allow, reject, alert, or drop behavior to the domains in your target list.

      When logging is enabled and you choose Alert, traffic that matches the domain specifications generates an alert in the firewall's logs. Then, traffic either passes, is rejected, or drops based on other rules in the firewall policy.

      If the service returns an enum value that is not available in the current SDK version, generatedRulesType will return GeneratedRulesType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from generatedRulesTypeAsString().

      Returns:
      Whether you want to apply allow, reject, alert, or drop behavior to the domains in your target list.

      When logging is enabled and you choose Alert, traffic that matches the domain specifications generates an alert in the firewall's logs. Then, traffic either passes, is rejected, or drops based on other rules in the firewall policy.

      obj - the object to be compared with
      Returns:
      true if the other object equals to this object by sdk fields, false otherwise.
