What is Cyber Resilience

This chapter traces the evolution of cybersecurity skills requirements and development over the past 40 years, from the early days of computer security (Compusec) to the present day. The development of cybersecurity skills is traced from an initial focus upon national security and confidentiality through to the current recognition as business driver. The main part of the chapter concentrates on the development of a specific skills framework from the Institute of Information Security Professionals. Originally conceived in 2006 and initially used for purposes of membership accreditation, the IISP Skills Framework has since been used extensively by commerce, industry, government and academia in the UK and more widely. Version 2 of the framework was published in 2016, and the chapter discussion outlines both the original structure and the notable changes in the later release. These developments collectively illustrate the ongoing recognition of cybersecurity skills, as well as the evolution of the skills themselves.
