What Is ISO 27001?
ISO 27001 is an international standard that defines how to establish, implement, maintain, and continually improve an Information Security Management System (ISMS) to protect confidentiality, integrity, and availability of information. The standard requires organizations to follow a structured risk management approach, identifying threats, assessing impacts, and implementing appropriate controls.
Key components include an information security policy, risk assessment and treatment methodology, documented procedures, security controls from Annex A, staff awareness, incident management, and ongoing monitoring and improvement. Together, these elements help ensure that technical, physical, and organizational measures work in harmony, rather than relying on isolated tools
Why ISO 27001 Matters in Japan
Cyberattacks targeting Japanese businesses have grown in sophistication, impacting sectors such as finance, manufacturing, healthcare, and logistics. Attackers increasingly focus on cloud environments, supply chains, and third‑party vendors, which makes structured governance essential rather than ad‑hoc security.
