About CIBOK

The first edition of the Cybercrime Investigation Body of Knowledge (CIBOK) was established in 2016 by the CIBOK Editorial Committee. It was the first attempt to systematically organize the fundamental knowledge and skills required by practitioners involved in responding to cybercrime.
The Editor-in-Chief of both the first and second editions was Dr. Shane Shook, Ph.D.
The second edition was compiled in May 2025 by the CIBOK Editorial Committee, consisting of 18 authors from five countries and 26 reviewers, with contributions from 5 international cyber security companies, chaired by Hiroshi Nishino. Upon approval by the CIBOK Steering Committee, printing and publication of the second edition has commenced.
The purpose of the CIBOK Second Edition is to provide a systematic overview of the knowledge, skills, and attitudes required for handling cybercrime, conducting investigations, and operating and managing departments responsible for incident response, such as investigative units or CSIRTs. While maintaining the framework of the first edition, it introduces updated information and case studies from both public and private sector perspectives to promote broader understanding and support effective investigations and organizational operations.

The second edition of CIBOK is established with the same five objectives as the first edition:

  • Enables the acquisition of globally consistent common sense regarding cybercrime investigation, regardless of national laws.
  • Clarifies how to position and apply already established practical disciplines—such as project management, computer science, and digital forensics—in the context of cybercrime investigations.
  • Defines the practical content that should be applied in cybercrime investigations across eight knowledge domains.
  • Provides ample reference materials for a deeper understanding of the topics related to each of the eight domains.
  • Enables the development of training curricula and objective evaluation of individual knowledge and skills related to cybercrime investigations.

Target Audience for the Second Edition (unchanged from the first edition):

The second edition of CIBOK is written for individuals involved in or responsible for cybercrime investigations and incident response activities across public, private, and law enforcement sectors.

For investigators and prosecutors in law enforcement

For IT/Security managers and staff in private organizations

About the CIBOK Editorial Committee and Governance

In 2015, the CIBOK Steering Committee formed an organizational body focused on the coordination of cybercrime investigations with the social mission of protecting ICT-based society from cyber threats. Based on surveys and planning conducted at that time, a proposal was submitted to begin drafting the first edition of CIBOK.
Following this, in April 2016, the CIBOK Editorial Committee was formally established with Hiroshi Nishino as chair and Dr. Shane Shook as Editor-in-Chief.
The purpose of the CIBOK project was to conduct job analyses and other research among practitioners or experienced personnel to characterize the technologies, methodologies, processes, and procedures used in the field of cybercrime investigation—regardless of their ICT expertise. Each editorial committee member is expected to continuously monitor cybercrime-related trends and contribute to the characterization of relevant elements. These identified items are periodically brought to editorial meetings, where their significance is evaluated and refined through a layered structuring of knowledge domains. Given the time that has passed since the first edition, the editorial committee undertook comprehensive discussions and revisions of each chapter. As with the first edition, Dr. Shane Shook led the editing process, and the revised content was reviewed by an even broader group of subject-matter experts to produce the Second Edition.
