Critical infrastructure protection U S Government Accountability Office

" Critical infrastructures are systems and assets critical to the nation's security, economy, and public health and safety, most of which are owned by the private sector. These assets rely on networked computers and systems, thus making them susceptible to cyber-based risks. Managing such risk involves the use of cybersecurity guidance that promotes or requires actions to enhance the confidentiality, integrity, and availability of computer systems. For seven critical infrastructure sectors, GAO was asked to identify (1) cybersecurity guidance for entities within the sectors, (2) the extent to which implementation of this guidance is enforced and promoted, and (3) areas of commonalities and differences between sector cybersecurity guidance and guidance applicable to federal agencies. To do this, GAO collected and analyzed information from responsible private sector coordinating councils; federal agencies, including sector-specific agencies that are responsible for coordinating critical infrastructure protection efforts; and standards-making bodies. In addition, GAO compared a set of guidance in each of three subsectors with guidance applicable to federal agencies. "
