Splunk takes security investigations one level deeper. Instead of just monitoring log data, you can also run Splunk as a forwarder on your boxes to regularly index run-time information, such as the running processes, or the open ports and network connections. In addition, by running Splunk on your machine, you can also monitor the file system of your machines. This additional information greatly helps investigate security incidents and gather additional information.

The Splunk for Network Security application is a way to get you started with your network security needs. The application contains a variety of searches, reports, dashboards, and alerts to provide visibility into your network, and also help monitor for specific violations.
