+## Network Firewall service events
+
+Network Firewall sends the following events directly to EventBridge: 
+
+  * Firewall Configuration Changed
+
+  * Firewall Attachment Status Changed
+
+  * Firewall Transit Gateway Attachment Status Changed
+
+
+
+
+_Delivery type_ : [ Durable ](./event-delivery-level.html)
+
+To match against all events from this service, create an event pattern that matches against the following event attribute:
+
+  * `source`: aws.network-firewall
+
+
+
+    
+    
+    {
+      "source": ["aws.network-firewall"]
+    }
+
+To match against specific events, include a `detail-type` attribute specifying an array of event names to match. For example:
+    
+    
+    {
+      "source": ["aws.network-firewall"],
+      "detail-type": ["Firewall Configuration Changed"]
+    }
+
