Class RuleDefinition

    • Method Detail

      • matchAttributes

        public final MatchAttributes matchAttributes()

        Criteria for Network Firewall to use to inspect an individual packet in stateless rule inspection. Each match attributes set can include one or more items such as IP address, CIDR range, port number, protocol, and TCP flags.

        Returns:
        Criteria for Network Firewall to use to inspect an individual packet in stateless rule inspection. Each match attributes set can include one or more items such as IP address, CIDR range, port number, protocol, and TCP flags.

      • hasActions

        public final boolean hasActions()
        For responses, this returns true if the service returned a value for the Actions 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.

      • actions

        public final List<String> actions()

        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”] .

        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 hasActions() method.

        Returns:
