The ISO/IEC 27000 series provides best practice recommendations for information security management. It covers establishing, implementing, operating, monitoring, reviewing and improving an Information Security Management System (ISMS) based on assessing risks and implementing appropriate controls. The series incorporates continuous improvement using Deming's plan-do-check-act approach to address evolving threats, vulnerabilities and incidents. Key standards in the series specify ISMS requirements, guidelines for implementation and auditing, and guidance on risk management, measurements and certification.

The series provides best practice recommendations on information security management, risks and controls within the
context of an overall Information Security Management System (ISMS). The series is a deliberately broad in scope,
covering more than just privacy, confidentiality and IT or technical security issues. All organizations are encouraged to
assess their information security risks, then implement appropriate information security controls according to their needs,
using the guidance and suggestions where relevant. The ISMS concept incorporates continuous feedback and
improvement activities, summarized by Deming's "plan-do-check-act" approach, that seek to address changes in the
threats, vulnerabilities or impacts of information security incidents.
