Congressional Budget Office Cost Estimate: H.R. 3359, Cybersecurity and Infrastructure Security Agency Act of 2017 [open pdf - 85KB]
"H.R. 3359 would rename the National Protection and Programs Directorate (NPPD) of the Department of Homeland Security (DHS) as the Cybersecurity and Infrastructure Security Agency. The bill also would consolidate certain missions of NPPD under two divisions: the Cybersecurity Division and the Infrastructure Security Division. Based on information from DHS, CBO [Congressional Budget Office] has concluded that the requirements in the bill would not impose any new operating requirements on the agency. On that basis, CBO estimates that implementing H.R. 3359 would have a negligible effect on the federal budget."
