list-firewall-rules

Description

Retrieves the firewall rules that you have defined for the specified firewall rule group. DNS Firewall uses the rules in a rule group to filter DNS network traffic for a VPC.

A single call might return only a partial list of the rules. For information, see MaxResults .

See also: AWS API Documentation

list-firewall-rules is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: FirewallRules

Options

--firewall-rule-group-id (string)

The unique identifier of the firewall rule group that you want to retrieve the rules for.

--priority (integer)

Optional additional filter for the rules to retrieve.

The setting that determines the processing order of the rules in a rule group. DNS Firewall processes the rules in a rule group by order of priority, starting from the lowest setting.

--action (string)

Optional additional filter for the rules to retrieve.

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:

  • ALLOW - Permit the request to go through. Not availabe for DNS Firewall Advanced rules.
  • ALERT - Permit the request to go through but send an alert to the logs.
  • BLOCK - Disallow the request. If this is specified, additional handling details are provided in the rule's BlockResponse setting.

Possible values:

  • ALLOW
  • BLOCK
  • ALERT

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command's output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command's output. If the total number of items available is more than the value specified, a NextToken is provided in the command's output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

  • BLOCK - Disallow the request. If this is specified, additional handling details are provided in the rule's BlockResponse setting.

BlockResponse -> (string)

The way that you want DNS Firewall to block the request. Used for the rule action setting BLOCK .

  • NODATA - Respond indicating that the query was successful, but no response is available for it.
  • NXDOMAIN - Respond indicating that the domain name that's in the query doesn't exist.
  • OVERRIDE - Provide a custom override in the response. This option requires custom handling details in the rule's BlockOverride* settings.

BlockOverrideDomain -> (string)

The custom DNS record to send back in response to the query. Used for the rule action BLOCK with a BlockResponse setting of OVERRIDE .

BlockOverrideDnsType -> (string)

The DNS record's type. This determines the format of the record value that you provided in BlockOverrideDomain . Used for the rule action BLOCK with a BlockResponse setting of OVERRIDE .

BlockOverrideTtl -> (integer)

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 BLOCK with a BlockResponse setting of OVERRIDE .

CreatorRequestId -> (string)

The type of the DNS Firewall Advanced rule. Valid values are:

  • DGA : Domain generation algorithms detection. DGAs are used by attackers to generate a large number of domains to to launch malware attacks.
  • DNS_TUNNELING : 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.

ConfidenceThreshold -> (string)

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:

  • LOW : Provides the highest detection rate for threats, but also increases false positives.
