Create a new AWS::NetworkFirewall::RuleGroup.

Parameters:

scope (Construct) –
- scope in which this resource is defined.
id (str) –
- scoped id of the resource.
capacity (Union[int, float]) – The maximum operating resources that this rule group can use. You can’t change a rule group’s capacity setting after you create the rule group. 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.
rule_group_name (str) – The descriptive name of the rule group. You can’t change the name of a rule group after you create it.
type (str) – 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.
description (Optional[str]) – A description of the rule group.
rule_group (Union[IResolvable, RuleGroupProperty, Dict[str, Any], None]) – An object that defines the rule group rules.
tags (Optional[Sequence[Union[CfnTag, Dict[str, Any]]]]) – An array of key-value pairs to apply to this resource. For more information, see Tag .

Methods

add_deletion_override(path)

Syntactic sugar for addOverride(path, undefined).

Parameters:: path (str) – The path of the value to delete.
Return type:: None

add_depends_on(target)

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.

Parameters:

target (CfnResource) –

Return type:

None

add_metadata(key, value)

Add a value to the CloudFormation Resource Metadata.

Parameters:

key (str) –
value (Any) –

See:

Return type:

None

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

add_override(path, value)

Adds an override to the synthesized CloudFormation resource.

To add a property override, either use addPropertyOverride or prefix path with “Properties.” (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example:

cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"])
cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE")

would add the overrides Example:

"Properties": {
   "GlobalSecondaryIndexes": [
     {
       "Projection": {
         "NonKeyAttributes": [ "myattribute" ]
         ...
       }
       ...
     },
     {
       "ProjectionType": "INCLUDE"
       ...
     },
   ]
   ...
}

The value argument to addOverride will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.

Parameters:

path (str) –
- The path of the property, you can use dot notation to override values in complex types. Any intermdediate keys will be created as needed.
value (Any) –
- The value. Could be primitive or complex.

Return type:

None

add_property_deletion_override(property_path)

Adds an override that deletes the value of a property from the resource definition.

Parameters:: property_path (str) – The path to the property.
Return type:: None

add_property_override(property_path, value)

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).

Parameters:

property_path (str) – The path of the property.
value (Any) – The value.

Return type:

None

apply_removal_policy(policy=None, *, apply_to_update_replace_policy=None, default=None)

Sets the deletion policy of the resource based on the removal policy specified.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you’ve removed it from the CDK application or because you’ve made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN).

Parameters:

policy (Optional[RemovalPolicy]) –
apply_to_update_replace_policy (Optional[bool]) – Apply the same deletion policy to the resource’s “UpdateReplacePolicy”. Default: true
default (Optional[RemovalPolicy]) – The default policy to apply in case the removal policy is not defined. Default: - Default value is resource specific. To determine the default value for a resoure, please consult that specific resource’s documentation.

Return type:

None

get_att(attribute_name)

Returns a token for an runtime attribute of this resource.

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.

Parameters:: attribute_name (str) – The name of the attribute.
Return type:: Reference

get_metadata(key)

Retrieve a value value from the CloudFormation Resource Metadata.

Parameters:

key (str) –

See:

Return type:

Any

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

inspect(inspector)

Examines the CloudFormation resource and discloses attributes.

Parameters:

inspector (TreeInspector) –

tree inspector to collect and process attributes.

Return type:

None

override_logical_id(new_logical_id)

Overrides the auto-generated logical ID with a specific ID.

Parameters:: new_logical_id (str) – The new logical ID to use for this stack element.
Return type:: None

to_string()

Returns a string representation of this construct.

Return type:: str
Returns:: a string representation of this resource

Attributes

CFN_RESOURCE_TYPE_NAME = 'AWS::NetworkFirewall::RuleGroup'

attr_rule_group_arn

attr_rule_group_id

The unique ID of the RuleGroup resource.

CloudformationAttribute:: RuleGroupId

capacity

The maximum operating resources that this rule group can use.

You can’t change a rule group’s capacity setting after you create the rule group. 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.

A description of the rule group.

Link:: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-networkfirewall-rulegroup.html#cfn-networkfirewall-rulegroup-description

logical_id

The logical ID for this CloudFormation stack element.

The logical ID of the element is calculated from the path of the resource node in the construct tree.

To override this value, use overrideLogicalId(newLogicalId).

Returns:

the logical ID as a stringified token. This value will only get resolved during synthesis.

node: The construct tree node associated with this construct.

ref

Return a string that will be resolved to a CloudFormation { Ref } for this element.

If, by any chance, the intrinsic reference of a resource is not a string, you could coerce it to an IResolvable through Lazy.any({ produce: resource.ref }).

bool

Returns:

The construct as a stack element or undefined if it is not a stack element.

classmethod is_cfn_resource(construct)

Check whether the given construct is a CfnResource.

ActionDefinitionProperty

class CfnRuleGroup.ActionDefinitionProperty(*, publish_metric_action=None)

Bases: object

A custom action to use in stateless rule actions settings.

Parameters:: publish_metric_action (Union[IResolvable, PublishMetricActionProperty, Dict[str, Any], None]) – Stateless inspection criteria that publishes the specified metrics to Amazon CloudWatch for the matching packet. This setting defines a CloudWatch dimension value to be published. You can pair this custom action with any of the standard stateless rule actions. For example, you could pair this in a rule action with the standard action that forwards the packet for stateful inspection. Then, when a packet matches the rule, Network Firewall publishes metrics for the packet and forwards it.

CustomActionProperty

class CfnRuleGroup.CustomActionProperty(*, action_definition, action_name)

Bases: object

An optional, non-standard action to use for stateless packet handling.

You can define this in addition to the standard action that you must specify.

You define and name the custom actions that you want to be able to use, and then you reference them by name in your actions settings.

You can use custom actions in the following places:

In an RuleGroup.StatelessRulesAndCustomActions . The custom actions are available for use by name inside the StatelessRulesAndCustomActions where you define them. You can use them for your stateless rule actions to specify what to do with a packet that matches the rule’s match attributes.
In an FirewallPolicy specification, in StatelessCustomActions . The custom actions are available for use inside the policy where you define them. You can use them for the policy’s default stateless actions settings to specify what to do with packets that don’t match any of the policy’s stateless rules.

Parameters:

action_definition (Union[IResolvable, ActionDefinitionProperty, Dict[str, Any]]) – The custom action associated with the action name.
action_name (str) – The descriptive name of the custom action. You can’t change the name of a custom action after you create it.

RulesSourceListProperty

class CfnRuleGroup.RulesSourceListProperty(*, generated_rules_type, targets, target_types)

Bases: object

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 RuleGroup.RuleVariables in this guide and Stateful domain list rule groups in AWS Network Firewall in the Network Firewall Developer Guide

Parameters:

generated_rules_type (str) – Whether you want to allow or deny access to the domains in your target list.
targets (Sequence[str]) – 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 .
target_types (Sequence[str]) – The types of targets to inspect for. Valid values are TLS_SNI and HTTP_HOST .

RulesSourceProperty

class CfnRuleGroup.RulesSourceProperty(*, rules_source_list=None, rules_string=None, stateful_rules=None, stateless_rules_and_custom_actions=None)

Bases: object

The stateless or stateful rules definitions for use in a single rule group.

Each rule group requires a single RulesSource . You can use an instance of this for either stateless rules or stateful rules.

Parameters:

rules_source_list (Union[IResolvable, RulesSourceListProperty, Dict[str, Any], None]) – Stateful inspection criteria for a domain list rule group.
rules_string (Optional[str]) – Stateful inspection criteria, provided in Suricata compatible intrusion prevention system (IPS) rules. Suricata is an open-source network IPS that includes a standard rule-based language for network traffic inspection. These rules contain the inspection criteria and the action to take for traffic that matches the criteria, so this type of rule group doesn’t have a separate action setting.
stateful_rules (Union[IResolvable, Sequence[Union[IResolvable, StatefulRuleProperty, Dict[str, Any]]], None]) – An array of individual stateful rules inspection criteria to be used together in a stateful rule group. Use this option to specify simple Suricata rules with protocol, source and destination, ports, direction, and rule options. For information about the Suricata Rules format, see Rules Format .
stateless_rules_and_custom_actions (Union[IResolvable, StatelessRulesAndCustomActionsProperty, Dict[str, Any], None]) – Stateless inspection criteria to be used in a stateless rule group.

StatefulRuleProperty

class CfnRuleGroup.StatefulRuleProperty(*, action, header, rule_options)

Bases: object

A single Suricata rules specification, for use in a stateful rule group.

Use this option to specify a simple Suricata rule with protocol, source and destination, ports, direction, and rule options. For information about the Suricata Rules format, see Rules Format .

Parameters:

action (str) – 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 . - REJECT - Drops traffic that matches the conditions of the stateful rule and sends a TCP reset packet back to sender of the packet. A TCP reset packet is a packet with no payload and a RST bit contained in the TCP header flags. REJECT is available only for TCP traffic. - 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 . - REJECT - Drops TCP traffic that matches the conditions of the stateful rule, and sends a TCP reset packet back to sender of the packet. A TCP reset packet is a packet with no payload and a RST bit contained in the TCP header flags. Also sends an alert log mesage if alert logging is configured in the Firewall LoggingConfiguration . REJECT isn’t currently available for use with IMAP and FTP protocols.
header (Union[IResolvable, HeaderProperty, Dict[str, Any]]) – The stateful inspection criteria for this rule, used to inspect traffic flows.
rule_options (Union[IResolvable, Sequence[Union[IResolvable, RuleOptionProperty, Dict[str, Any]]]]) – Additional settings for a stateful rule, provided as keywords and settings.

Attributes

action

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 .
REJECT - Drops traffic that matches the conditions of the stateful rule and sends a TCP reset packet back to sender of the packet. A TCP reset packet is a packet with no payload and a RST bit contained in the TCP header flags. REJECT is available only for TCP traffic.
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 .

REJECT - Drops TCP traffic that matches the conditions of the stateful rule, and sends a TCP reset packet back to sender of the packet. A TCP reset packet is a packet with no payload and a RST bit contained in the TCP header flags. Also sends an alert log mesage if alert logging is configured in the Firewall LoggingConfiguration .

REJECT isn’t currently available for use with IMAP and FTP protocols.

StatelessRuleProperty

class CfnRuleGroup.StatelessRuleProperty(*, priority, rule_definition)

Bases: object

A single stateless rule.

This is used in RuleGroup.StatelessRulesAndCustomActions .

Parameters:

priority (Union[int, float]) – 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.
rule_definition (Union[IResolvable, RuleDefinitionProperty, Dict[str, Any]]) – Defines the stateless 5-tuple packet inspection criteria and the action to take on a packet that matches the criteria.

Parameters:

flags (Sequence[str]) – 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 (Optional[Sequence[str]]) – The set of flags to consider in the inspection. To inspect all flags in the valid values list, leave this with no setting.
