ISO/IEC 27001 (commonly called ISO 27001) is the world’s best-known standard for establishing, implementing, maintaining, and continually improving an Information Security Management System (ISMS). It provides a risk-based framework to protect information across people, processes, and technology—not just IT systems.
What Is ISO 27001?
ISO 27001 defines requirements for an ISMS, including:
– Defining the scope of what information and systems are covered
– Performing information security risk assessment and risk treatment
– Implementing controls and governance to manage risks
– Monitoring, auditing, and continual improvement of the ISMS
Why ISO 27001 Matters in EV Charging
EV charging ecosystems include connected chargers, backends, mobile apps, payments, and roaming—so information security affects real-world operations. ISO 27001 helps operators and OEMs:
– Protect charger and backend credentials (certificates, keys, admin access)
– Reduce risk of service disruption and improve uptime through structured controls
– Improve security governance aligned with OT/critical infrastructure expectations
– Demonstrate assurance to enterprise customers and public tenders
ISO 27001 and Annex A Controls
ISO 27001 includes Annex A—a reference set of security controls used to treat risks. In ISO/IEC 27001:2022, Annex A contains 93 controls grouped into four themes:
– Organizational controls
– People controls
– Physical controls
– Technological controls
Organizations select the controls that fit their risk assessment and document them in a Statement of Applicability (SoA).
What ISO 27001 Certification Typically Involves
Certification (where pursued) usually requires:
– Documented ISMS scope, policies, and risk treatment approach
– Evidence that chosen controls are implemented and effective
– Internal audits and management review
– External audit by an accredited certification body
