This book explores the Bank Secrecy Act (BSA), which is a legislative framework for combating money laundering. The Financial Crimes Enforcement Network (FinCEN) is responsible for the administration of the BSA regulatory structure, and has delegated examination responsibility to the federal banking regulators. This book describes how BSA compliance and enforcement responsibilities are distributed, how agencies other than FinCEN are implementing those responsibilities and the evaluation of their co-ordination efforts. This book also discusses security policies and controls for systems at three organisations to evaluate whether security controls effectively protect the confidentiality, integrity and availability of the information and systems that support FinCEN's mission. This book consists of public documents which have been located, gathered, combined, reformatted, and enhanced with a subject index, selectively edited and bound to provide easy access.
