Gigamon Insight Add-on for Splunk

Overview
Details
Overview
The Gigamon Insight Splunk Add-on allows administrators to incorporate the network telemetry data collected and analyzed by the Gigamon Insight solution into their Splunk deployment. This add-on leverages Insight’s fully RESTful APIs to interact with the cloud backend to introduce specific data sets into Splunk. With this add-on, the Insight Query Language (IQL) can be used to import specific network events (such as HTTP, DNS, SMB, Kerberos, Suricata, and more) and all the associated metadata into Splunk. After the initial import, the add-on will periodically poll Insight at a specified interval for new match events to import. Detections and reports generated by Insight can also be imported, and the add-on will periodically poll Insight at a specified interval for new detections and reports to import. Enrichment and intelligence can also be imported for specified entities, such as WHOIS information, VirusTotal reports, Passive DNS records, and DHCP records.
