标准简介
ISO/IEC 27001 是全球最知名的信息安全管理体系（ISMS）标准。由国际标准化组织（ISO）和国际电工委员会（IEC）发布，定义了 ISMS 必须满足的保护敏感信息的要求。
采用此标准表明组织致力于有效管理信息安全风险。它有助于保护资产，确保遵守法律义务，并在全球范围内与利益相关者和客户建立信任。
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.
