This document serves as an introduction to the topic of Information Sharing and Analysis Organizations (ISAOs) and to the series of documents developed to assist newly forming ISAOs.
The establishment of ISAOs allows communities of interest to share cyber threat information with each other on a voluntary basis and to then analyze the shared information to provide guidance or assistance to ISAO members. The goal is to create deeper and broader networks of information sharing to elevate the security of the nation and those entities participating in ISAOs.
