An information security management system (ISMS) is a set of policies concerned with information security management or IT related risks. The governing principle behind an ISMS is that an organization should design, implement and maintain a coherent set of policies, processes and systems to manage risks to its information assets, thus ensuring acceptable levels of information security risk

ISO/IEC 27001 is an internationally recognized best practice framework for an information security management system (ISMS). It belongs to the ISO 27000 series of standards (including ISO 27002 and ISO 27005). It helps you identify the risks to your important information and put in place the appropriate controls to help reduce the risk.
