+  We can use Logstash to enrich Sysmon Event ID 1 with data cached in Memcached. 
+  Here is the config example:
+
+  ```
+  filter {
+    # Get previously cached information about parent process from cache to enrich process creation events (event id 1)
+    if [source_name] == "Microsoft-Windows-Sysmon" and [event_id] == 1 and [event_data][ParentProcessGuid] {
+      # Enrich event with additional information about process
+      memcached {
+        # get info from cache
+        hosts => ["127.0.0.1:11211"]
+        get => {
+          "%{computer_name}_%{[event_data][ParentProcessGuid]}" => "[@metadata][processinfo]"
+        }
+      }
+      if [@metadata][processinfo] {
+        kv {
+          source => "[@metadata][processinfo]"
+          target => "[@metadata][processinfo]"
+          field_split => ","
+          value_split => "="
+        }
+        if [@metadata][processinfo][ParentImage] {
+          mutate {
+            add_field => { "[event_data][ParentIntegrityLevel]" => "%{[@metadata][processinfo][IntegrityLevel]}" }
+            add_field => { "[event_data][ParentUser]" => "%{[@metadata][processinfo][User]}" }
+            add_field => { "[event_data][ParentOfParentImage]" => "%{[@metadata][processinfo][ParentImage]}" }
+          }
+        }
+      }
+    }
+  }
+  ```
