How will DHS know that it is addressing the highest risk facilities first?
Facilities that are placed into a tier based on the results of their Top Screen have the potential to create significant security related consequences. These facilities are required to complete a Security Vulnerability Assessment (SVA). The SVA provides more in-depth information that allows DHS to assign a final risk tier ranking to the facility. The highest tier facilities or Phase 1 facilities are addressed by DHS first. Facilities that complete the CSAT Top Screen and do not meet the consequence thresholds are not obligated to comply with CFATS.
