Definition
An Information Security Management System (ISMS) is a structured management system for governing information-security risks, responsibilities, policies, controls, evidence and continual improvement. It provides the organizational framework behind standards such as ISO/IEC 27001 and helps ensure that information-security requirements are managed consistently rather than as isolated technical measures.
Why it matters
For Quality, IT and procurement stakeholders evaluating an eQMS or other SaaS platform, information security is part of system governance. Access control, auditability, integrations, supplier responsibilities, business continuity and data exit all depend on a clear security-management framework and evidence that controls are operating as intended.
Define the information, services, organizational boundaries and interested-party requirements the ISMS needs to address.
