Homeland Security Advisories and Information Bulletins:

• Homeland Security Threat Advisories contain actionable information about an incident involving or a threat targeting critical national networks, infrastructures or key assets.  
   
• Homeland Security Information Bulletins communicate information of interest to the nation’s critical infrastructures that do not meet the timeliness, specificity or significance thresholds of warning messages.

The DHS/IAIP Daily Open Source Infrastructure Report (Daily Report) appears Monday through Friday and is a summary and assessment of open-source published information concerning significant critical infrastructure issues. Each Daily Report is divided by the critical infrastructure sectors and key assets defined in the National Strategy for the Physical Protection of Critical Infrastructures and Key Assets.
