Overview of this book

ISO 27001 and ISO 27002 are globally recognized standards for information security management systems (ISMSs), providing a robust framework for information protection that can be adapted to all organization types and sizes. Organizations with significant exposure to information-security–related risks are increasingly choosing to implement an ISMS that complies with ISO 27001. This book will help you understand the process of getting your organization's information security management system certified by an accredited certification body. The book begins by introducing you to the standards, and then takes you through different principles and terminologies. Once you completely understand these standards, you’ll explore their execution, wherein you find out how to implement these standards in different sizes of organizations. The chapters also include case studies to enable you to understand how you can implement the standards in your organization. Finally, you’ll get to grips with the auditing process, planning, techniques, and reporting and learn to audit for ISO 27001. By the end of this book, you’ll have gained a clear understanding of ISO 27001/27002 and be ready to successfully implement and audit for these standards.
