標準簡介
ISO/IEC 27001 是全球最知名的資訊安全管理系統（ISMS）標準。由國際標準化組織（ISO）和國際電工委員會（IEC）發布，它定義了資訊安全管理系統必須滿足的要求，以保護敏感資訊。
採用此標準表明組織承諾有效管理資訊安全風險。它有助於保護資產、確保符合法律義務，並在全球範圍內建立與利害關係人和客戶的信任。
Annex A Controls
Provides 93 reference controls across 4 themes — organizational, people, physical, and technological — to systematically reduce information security risks.
Risk Assessment
Mandates a formal risk assessment process to identify threats, vulnerabilities, and impacts, then select proportionate controls.
Continuous Monitoring
Requires ongoing measurement, analysis, and evaluation of ISMS performance through internal audits and management reviews.

- Organizational controls (policies, roles, asset management)
- People controls (screening, awareness, training)
- Physical controls (perimeters, equipment, media)
- Technological controls (access, cryptography, logging)
- Risk assessment & treatment methodology
- Statement of Applicability (SoA)
- Incident management & business continuity
Who Needs to Comply?
Organizations of any size that handle sensitive information — particularly technology companies, financial services, healthcare providers, and government contractors.
Key Requirements
Information Security Policy
Establish and maintain an information security policy approved by top management, communicated to all employees, and available to interested parties.
Risk Assessment & Treatment
Implement a repeatable risk assessment process. Produce a risk treatment plan and Statement of Applicability mapping selected Annex A controls to identified risks.
Access Control
Ensure only authorized users can access information and systems. Implement identity management, authentication, and access rights provisioning aligned with business needs.
Incident Response
Establish procedures to detect, report, assess, and respond to information security incidents. Learn from incidents to prevent recurrence.
Internal Audit Program
Conduct internal audits at planned intervals to verify the ISMS conforms to requirements and is effectively implemented and maintained.
Penalties & Enforcement
No direct legal penalties for non-certification. However, many procurement processes and regulations (e.g., GDPR, NIS2) effectively require ISO 27001 or equivalent controls. Loss of certification can disqualify organizations from contracts.
