The NCI is a true cross-sector partnership, providing a forum for sharing cyber and physical threats and mitigation strategies among ISACs and with government and private sector partners during both steady-state conditions and incidents requiring cross-sector response. Sharing and coordination is accomplished through daily and weekly calls between ISAC operations centers, daily reports, requests-for-information, monthly meetings, exercises, and other activities as situations require. The NCI also organizes its own drills and exercises and participates in national exercises.
