ISMS

An ISMS, or information security management system, is the documented set of policies, processes, roles, and controls a company uses to manage information risk on purpose rather than by accident. ISO 27001 defines what a certifiable ISMS must include: leadership involvement, a risk assessment method, treatment plans, measurable objectives, and regular internal audits. The idea is a repeating cycle where you plan protections, put them into practice, check whether they work, and fix what falls short. An ISMS covers people and processes as much as technology, so it shapes how an organization behaves, not only how its systems are configured.
