Information Systems Security: Challenges, Vulnerabilities and Tools
Philippe Cohard · 2019
This chapter discusses the security challenges related to the evolution of digital technologies, in particular the blockchain, a security mechanism that is the foundation of cryptocurrency. The two dimensions, “safety” and “security”, are fundamental to providing an overall level of security for the organization. The chapter provides a more detailed presentation of vulnerabilities, risks and how they are taken into account in the context of information system (IS) security policies. IS security is represented by the metaphor of the chain – as strong as its weakest link. IS threats can be classified according to four dimensions: external, internal, systems or human. Safety, security and awareness-raising and training must be structured and integrated into an information security management system. This structuring can be facilitated by the use of the ISO/IEC 27000 series standards.
