Client: Aws\NetworkFirewall\NetworkFirewallClient

Service ID: network-firewall

Version: 2020-11-12

This page describes the parameters and results for the operations of the AWS Network Firewall (2020-11-12), and shows how to use the Aws\NetworkFirewall\NetworkFirewallClient object to call the described operations. This documentation is specific to the 2020-11-12 API version of the service.

Operation Summary

Each of the following operations can be created from a client using $client->getCommand('CommandName'), where "CommandName" is the name of one of the following operations. Note: a command is a value that encapsulates an operation and the parameters used to create an HTTP request.

You can also create and send a command immediately using the magic methods available on a client object: $client->commandName(/* parameters */). You can send the command asynchronously (returning a promise) by appending the word "Async" to the operation name: $client->commandNameAsync(/* parameters */).

ListTagsForResource

Operations

AssociateFirewallPolicy

$result = $client->associateFirewallPolicy([/* ... */]);
$promise = $client->associateFirewallPolicyAsync([/* ... */]);

Associates a FirewallPolicy to a Firewall.

A firewall policy defines how to monitor and manage your VPC network traffic, using a collection of inspection rule groups and other settings. Each firewall requires one firewall policy association, and you can use the same firewall policy for multiple firewalls.

Parameter Syntax

$result = $client->associateFirewallPolicy([
    'FirewallArn' => '<string>',
    'FirewallName' => '<string>',
    'FirewallPolicyArn' => '<string>', // REQUIRED
    'UpdateToken' => '<string>',
]);

Parameter Details

Members

FirewallArn

Type: string

The Amazon Resource Name (ARN) of the firewall.

You must specify the ARN or the name, and you can specify both.

FirewallName

Type: string

The descriptive name of the firewall. You can't change the name of a firewall after you create it.

You must specify the ARN or the name, and you can specify both.

FirewallPolicyArn

Required: Yes
Type: string

The Amazon Resource Name (ARN) of the firewall policy.

UpdateToken

Type: string

An optional token that you can use for optimistic locking. Network Firewall returns a token to your requests that access the firewall. The token marks the state of the firewall resource at the time of the request.

To make an unconditional change to the firewall, omit the token in your update request. Without the token, Network Firewall performs your updates regardless of whether the firewall has changed since you last retrieved it.

To make a conditional change to the firewall, provide the token in your update request. Network Firewall uses the token to ensure that the firewall hasn't changed since you last retrieved it. If it has changed, the operation fails with an InvalidTokenException. If this happens, retrieve the firewall again to get a current copy of it with a new token. Reapply your changes as needed, then try the operation again using the new token.

CreateFirewall

$result = $client->createFirewall([/* ... */]);
$promise = $client->createFirewallAsync([/* ... */]);

Creates an AWS Network Firewall Firewall and accompanying FirewallStatus for a VPC.

The firewall defines the configuration settings for an AWS Network Firewall firewall. The settings that you can define at creation include the firewall policy, the subnets in your VPC to use for the firewall endpoints, and any tags that are attached to the firewall AWS resource.

After you create a firewall, you can provide additional settings, like the logging configuration.

To update the settings for a firewall, you use the operations that apply to the settings themselves, for example UpdateLoggingConfiguration, AssociateSubnets, and UpdateFirewallDeleteProtection.

To manage a firewall's tags, use the standard AWS resource tagging operations, ListTagsForResource, TagResource, and UntagResource.

To retrieve information about firewalls, use ListFirewalls and DescribeFirewall.

The call returns the value that the request would return if you ran it with dry run set to FALSE, but doesn't make additions or changes to your resources. This option allows you to make sure that you have the required permissions to run the request and that your request parameters are valid.

If set to FALSE, Network Firewall makes the requested changes to your resources.

FirewallPolicy

Required: Yes
Type: FirewallPolicy structure

The rule groups and policy actions to use in the firewall policy.

FirewallPolicyName

Required: Yes
Type: string

The descriptive name of the firewall policy. You can't change the name of a firewall policy after you create it.

Tags

Type: Array of Tag structures

Parameter Details

Members

Capacity

Required: Yes
Type: int

The maximum operating resources that this rule group can use. Rule group capacity is fixed at creation. When you update a rule group, you are limited to this capacity. When you reference a rule group from a firewall policy, Network Firewall reserves this capacity for the rule group.

You can retrieve the capacity that would be required for a rule group before you create the rule group by calling CreateRuleGroup with DryRun set to TRUE.

You can't change or exceed this capacity when you update the rule group, so leave room for your rule group to grow.

Capacity for a stateless rule group

For a stateless rule group, the capacity required is the sum of the capacity requirements of the individual rules that you expect to have in the rule group.

To calculate the capacity requirement of a single rule, multiply the capacity requirement values of each of the rule's match settings:

A match setting with no criteria specified has a value of 1.
A match setting with Any specified has a value of 1.
All other match settings have a value equal to the number of elements provided in the setting. For example, a protocol setting ["UDP"] and a source setting ["10.0.0.0/24"] each have a value of 1. A protocol setting ["UDP","TCP"] has a value of 2. A source setting ["10.0.0.0/24","10.0.0.1/24","10.0.0.2/24"] has a value of 3.

A rule with no criteria specified in any of its match settings has a capacity requirement of 1. A rule with protocol setting ["UDP","TCP"], source setting ["10.0.0.0/24","10.0.0.1/24","10.0.0.2/24"], and a single specification or no specification for each of the other match settings has a capacity requirement of 6.

Capacity for a stateful rule group

For a stateful rule group, the minimum capacity required is the number of individual rules that you expect to have in the rule group.

Description

Type: string

A description of the rule group.

DryRun

Type: boolean

Indicates whether you want Network Firewall to just check the validity of the request, rather than run the request.

If set to FALSE, Network Firewall makes the requested changes to your resources.

RuleGroup

Type: RuleGroup structure

An object that defines the rule group rules.

You must provide either this rule group setting or a Rules setting, but not both.

RuleGroupName

Required: Yes
Type: string

The descriptive name of the rule group. You can't change the name of a rule group after you create it.

Rules

Type: string

A string containing stateful rule group rules specifications in Suricata flat format, with one rule per line. Use this to import your existing Suricata compatible rule groups.

You must provide either this rules setting or a populated RuleGroup setting, but not both.

You can provide your rule group specification in Suricata flat format through this setting when you create or update your rule group. The call response returns a RuleGroup object that Network Firewall has populated from your string.

Tags

Type: Array of Tag structures

The key:value pairs to associate with the resource.

Type

Required: Yes
Type: string

Indicates whether the rule group is stateless or stateful. If the rule group is stateless, it contains stateless rules. If it is stateful, it contains stateful rules.

RuleGroupResponse

Required: Yes
Type: RuleGroupResponse structure

The high-level properties of a rule group. This, along with the RuleGroup, define the rule group. You can retrieve all objects for a rule group by calling DescribeRuleGroup.

UpdateToken

Required: Yes
Type: string

A token used for optimistic locking. Network Firewall returns a token to your requests that access the rule group. The token marks the state of the rule group resource at the time of the request.

To make changes to the rule group, you provide the token in your request. Network Firewall uses the token to ensure that the rule group hasn't changed since you last retrieved it. If it has changed, the operation fails with an InvalidTokenException. If this happens, retrieve the rule group again to get a current copy of it with a current token. Reapply your changes as needed, then try the operation again using the new token.

Errors

LimitExceededException:
Unable to perform the operation because doing so would violate a limit setting.
InvalidRequestException:
The operation failed because of a problem with your request. Examples include:
- You specified an unsupported parameter name or value.
- You tried to update a property with a value that isn't among the available types.
- Your request references an ARN that is malformed, or corresponds to a resource that isn't valid in the context of the request.
ThrottlingException:
Unable to process the request due to throttling limitations.
InternalServerError:
Your request is valid, but Network Firewall couldn’t perform the operation because of a system problem. Retry your request.
InsufficientCapacityException:
AWS doesn't currently have enough available capacity to fulfill your request. Try your request later.

DeleteFirewall

$result = $client->deleteFirewall([/* ... */]);
$promise = $client->deleteFirewallAsync([/* ... */]);

Deletes the specified Firewall and its FirewallStatus. This operation requires the firewall's DeleteProtection flag to be FALSE. You can't revert this operation.

You can check whether a firewall is in use by reviewing the route tables for the Availability Zones where you have firewall subnet mappings. Retrieve the subnet mappings by calling DescribeFirewall. You define and update the route tables through Amazon VPC. As needed, update the route tables for the zones to remove the firewall endpoints. When the route tables no longer use the firewall endpoints, you can remove the firewall safely.

To delete a firewall, remove the delete protection if you need to using UpdateFirewallDeleteProtection, then delete the firewall by calling DeleteFirewall.

LogDestinationConfig

Description

Defines where AWS Network Firewall sends logs for the firewall for one log type. This is used in LoggingConfiguration. You can send each type of log to an Amazon S3 bucket, a CloudWatch log group, or a Kinesis Data Firehose delivery stream.

Network Firewall generates logs for stateful rule groups. You can save alert and flow log types. The stateful rules engine records flow logs for all network traffic that it receives. It records alert logs for traffic that matches stateful rules that have the rule action set to DROP or ALERT.

Members

LogDestination

Required: Yes
Type: Associative array of custom strings keys (HashMapKey) to strings

The named location for the logs, provided in a key:value mapping that is specific to the chosen destination type.

"LogDestination": { "bucketName": "DOC-EXAMPLE-BUCKET", "prefix": "alerts" }
For a CloudWatch log group, provide the name of the CloudWatch log group, with key logGroup. The following example specifies a log group named alert-log-group:

"LogDestination": { "logGroup": "alert-log-group" }
For a Kinesis Data Firehose delivery stream, provide the name of the delivery stream, with key deliveryStream. The following example specifies a delivery stream named alert-delivery-stream:

"LogDestination": { "deliveryStream": "alert-delivery-stream" }

RuleDefinition

Description

The inspection criteria and action for a single stateless rule. AWS Network Firewall inspects each packet for the specified matching criteria. When a packet matches the criteria, Network Firewall performs the rule's actions on the packet.

Members

Actions

Required: Yes
Type: Array of strings

The actions to take on a packet that matches one of the stateless rule definition's match attributes. You must specify a standard action and you can add custom actions.

Network Firewall only forwards a packet for stateful rule inspection if you specify aws:forward_to_sfe for a rule that the packet matches, or if the packet doesn't match any stateless rule and you specify aws:forward_to_sfe for the StatelessDefaultActions setting for the FirewallPolicy.

For every rule, you must specify exactly one of the following standard actions.

aws:pass - Discontinues all inspection of the packet and permits it to go to its intended destination.
aws:drop - Discontinues all inspection of the packet and blocks it from going to its intended destination.
aws:forward_to_sfe - Discontinues stateless inspection of the packet and forwards it to the stateful rule engine for inspection.

Additionally, you can specify a custom action. To do this, you define a custom action by name and type, then provide the name you've assigned to the action in this Actions setting. For information about the options, see CustomAction.

To provide more than one action in this setting, separate the settings with a comma. For example, if you have a custom PublishMetrics action that you've named MyMetricsAction, then you could specify the standard action aws:pass and the custom action with [“aws:pass”, “MyMetricsAction”].

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 AWS Network Firewall in the Network Firewall Developer Guide

Members

GeneratedRulesType

Required: Yes

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.

StatefulRule

Description

A single 5-tuple stateful rule, for use in a stateful rule group.

Members

Action

Required: Yes
Type: string

Defines what Network Firewall should do with the packets in a traffic flow when the flow matches the stateful rule criteria. For all actions, Network Firewall performs the specified action and discontinues stateful inspection of the traffic flow.

The actions for a stateful rule are defined as follows:

PASS - Permits the packets to go to the intended destination.
DROP - Blocks the packets from going to the intended destination and sends an alert log message, if alert logging is configured in the Firewall LoggingConfiguration.
ALERT - Permits the packets to go to the intended destination and sends an alert log message, if alert logging is configured in the Firewall LoggingConfiguration.

You can use this action to test a rule that you intend to use to drop traffic. You can enable the rule with ALERT action, verify in the logs that the rule is filtering as you want, then change the action to DROP.

A single stateless rule. This is used in StatelessRulesAndCustomActions.

Members

Priority

Required: Yes
Type: int

A setting that indicates the order in which to run this rule relative to all of the rules that are defined for a stateless rule group. Network Firewall evaluates the rules in a rule group starting with the lowest priority setting. You must ensure that the priority settings are unique for the rule group.

Each stateless rule group uses exactly one StatelessRulesAndCustomActions object, and each StatelessRulesAndCustomActions contains exactly one StatelessRules object. To ensure unique priority settings for your rule groups, set unique priorities for the stateless rules that you define inside any single StatelessRules object.

You can change the priority settings of your rules at any time. To make it easier to insert rules later, number them so there's a wide range in between, for example use 100, 200, and so on.

RuleDefinition

Required: Yes
Type: RuleDefinition structure

Defines the stateless 5-tuple packet inspection criteria and the action to take on a packet that matches the criteria.

StatelessRuleGroupReference

Description

Identifier for a single stateless rule group, used in a firewall policy to refer to the rule group.

Members

Priority

Required: Yes

Members

SubnetId

Required: Yes
Type: string

The unique identifier for the subnet.

SyncState

Description

The status of the firewall endpoint and firewall policy configuration for a single VPC subnet.

For each VPC subnet that you associate with a firewall, AWS Network Firewall does the following:

Instantiates a firewall endpoint in the subnet, ready to take traffic.
Configures the endpoint with the current firewall policy settings, to provide the filtering behavior for the endpoint.

When you update a firewall, for example to add a subnet association or change a rule group in the firewall policy, the affected sync states reflect out-of-sync or not ready status until the changes are complete.

Members

Attachment

Type: Attachment structure

The attachment status of the firewall's association with a single VPC subnet. For each configured subnet, Network Firewall creates the attachment by instantiating the firewall endpoint in the subnet so that it's ready to take traffic. This is part of the FirewallStatus.

Config

Type: Associative array of custom strings keys (ResourceName) to PerObjectStatus structures

The configuration status of the firewall endpoint in a single VPC subnet. Network Firewall provides each endpoint with the rules that are configured in the firewall policy. Each time you add a subnet or modify the associated firewall policy, Network Firewall synchronizes the rules in the endpoint, so it can properly filter network traffic. This is part of the FirewallStatus.

TCPFlagField

Members

Flags

Required: Yes
Type: Array of strings

Used in conjunction with the Masks setting to define the flags that must be set and flags that must not be set in order for the packet to match. This setting can only specify values that are also specified in the Masks setting.

For the flags that are specified in the masks setting, the following must be true for the packet to match:

The ones that are set in this flags setting must be set in the packet.
The ones that are not set in this flags setting must also not be set in the packet.

Masks

Type: Array of strings

The set of flags to consider in the inspection. To inspect all flags in the valid values list, leave this with no setting.

Tag

Description

A key:value pair associated with an AWS resource. The key:value pair can be anything you define. Typically, the tag key represents a category (such as "environment") and the tag value represents a specific value within that category (such as "test," "development," or "production"). You can add up to 50 tags to each AWS resource.
