Implementing.an.Information.Security.Management.System— Plan–Do–Check–Act

This chapter presents direction on how to implement an information security management system (ISMS). The ISMS development is a systematic process, and the material herein provides a description of the process, supporting tools, templates, and document outlines. In brief, the ISMS development process follows the PlanDo-Check-Act (PDCA) model and uses security control detail from ISO 27002. The level of detail and documentation depends first on the security goals of the organization and second on the desire to obtain ISO 27001 certification. Certification often requires a more strict set of documents, process, and controls-more on this in Chapter 5, “Audit and Certification.”
