- Enclosing class:
CfnRuleGroup
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.
Example:
// The code below shows an example of how to instantiate this type. // The values are placeholders you should change. import software.amazon.awscdk.services.networkfirewall.*; RuleDefinitionProperty ruleDefinitionProperty = RuleDefinitionProperty.builder() .actions(List.of("actions")) .matchAttributes(MatchAttributesProperty.builder() .destinationPorts(List.of(PortRangeProperty.builder() .fromPort(123) .toPort(123) .build())) .destinations(List.of(AddressProperty.builder() .addressDefinition("addressDefinition") .build())) .protocols(List.of(123)) .sourcePorts(List.of(PortRangeProperty.builder() .fromPort(123) .toPort(123) .build())) .sources(List.of(AddressProperty.builder() .addressDefinition("addressDefinition") .build())) .tcpFlags(List.of(TCPFlagFieldProperty.builder() .flags(List.of("flags")) // the properties below are optional .masks(List.of("masks")) .build())) .build()) .build();

Method Details
-
getActions
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 specifyaws:forward_to_sfe
for theStatelessDefaultActions
setting for theFirewallPolicy
.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.To provide more than one action in this setting, separate the settings with a comma. For example, if you have a publish metrics custom action that you've named
MyMetricsAction
, then you could specify the standard actionaws:pass
combined with the custom action using[“aws:pass”, “MyMetricsAction”]
