You can use Amazon Neptune to store a graph of your network and use graph queries to answer questions like how many hosts are running a specific application.

Neptune can store and process billions of events to manage and secure your network. If you detect an event that is an anomaly, you can use Neptune to quickly understand how it might affect your network by querying for a graph pattern using the attributes of the event.

You can query Neptune to find other hosts or devices that may be compromised. For example, if you detect a malicious file on a host, Neptune can help you to find the connections between the hosts that spread the malicious file, and enable you to trace it to the original host that downloaded it.
