The Cybersecurity and Infrastructure Security Agency (CISA) uses the Homeland Security Information Network (HSIN) to provide a secure, web-based, collaborative system to share sensitive cyber-related information and news with select cybersecurity partners. The CISA Portal on HSIN enables the U.S. Government and its partners to enhance their shared situational awareness on cyber activities by promoting a collaborative workspace for cybersecurity-related discussions.
The Department of Homeland Security (DHS), through CISA, shares threat indicators and advisory information with public, private, and international partners in the network defense community of practice using the CISA Portal, which provides a number of features that enable collaboration and information sharing including:
- A secure messaging capability to allow CISA and its partners to communicate and coordinate during cybersecurity incidents.
- A document library to share documents, files, and indicators of compromise.
- A web conferencing solution for webinars and online meetings.
- A message board for communication and coordination.
