ISO 27001:2015 is an international standard for information security management systems (ISMS). It provides a structured framework for organizations to establish, implement, maintain, and continually improve their information security practices. ISO 27001:2015 outlines a set of controls categorized into 14 domains, known as Annex A, which are designed to help organizations protect their information assets. Below, I'll outline these domains along with the number of controls within each domain, and I'll also discuss the benefits of ISO 27001.
