The new Investigation Data Model (community.rsa.com/docs/DOC-62313) and Hunting Pack (community.rsa.com/docs/DOC-62301) with the associated Hunting Guide (
community.rsa.com/docs/DOC-62341) provide a new way for analysts to interact with their data and hunt for threats. The attached PDF provides a summary of the key points, and what changes you need to make to your RSA NetWitness deployment to make the most of the new content. Happy Hunting!
