The nation"s critical infrastructure sectors - such as public health, energy, water, and transportation -- rely on computerised information and systems to provide services to the public. To fulfil the requirement for a comprehensive plan, including cyber aspects, the Department of Homeland Security (DHS) issued a national plan in June 2006 for the sectors to use as a road map to enhance the protection of critical infrastructure. Lead federal agencies, referred to as sector-specific agencies, are responsible for co-ordinating critical infrastructure protection efforts, such as the development of plans that are specific to each sector. This book determines if these sector-specific plans address key aspects of cyber security, including cyber assets, key vulnerabilities, vulnerability reduction efforts, and recovery plans. To accomplish this, the authors analysed each sector-specific plan against criteria that were developed on the basis of DHS guidance. This book is an excerpted and indexed edition.
