Congressional Budget Office Cost Estimate: H.R. 3635: Safe and Secure Federal Websites Act of 2014 [open pdf - 12KB]
"CBO estimates that enacting H.R. 3635 would have no significant effect on the federal budget. The legislation would amend federal laws that protect the privacy of personally identifiable information collected by the government. Personally identifiable information includes any information that identifies an individual such as name, Social Security number, and medical or financial records. The legislation would prohibit an agency from deploying a new website until the agency's Chief Information Officer certifies that all such information is safe and secure. Existing federal websites would have 90 days following enactment of H.R. 3635 to comply with this requirement. The legislation also would require the Office of Management and Budget (OMB) to issue policies and procedures for agencies to follow in the event of a security breach of a federal data system that contains personally identifiable information."
