ISO/IEC 27002 Information security, cybersecurity and privacy protection — Information security controls

ISO/IEC 27002, titled "Information security, cybersecurity and privacy protection — Information security controls," is an international standard providing a comprehensive set of generic information security controls and implementation guidance. It serves as a practical guide for organizations to establish, implement, maintain, and continually improve an Information Security Management System (ISMS), complementing the requirements outlined in ISO/IEC 27001. While not a certification standard itself, ISO 27002 offers 93 controls across four main themes: Organizational, People, Physical, and Technological controls. Its purpose is to help organizations effectively manage information security risks, ensuring the confidentiality, integrity, and availability of information assets. For instance, it provides specific guidance for controls related to data privacy, which aligns with requirements from regulations like GDPR Article 32 on security of processing, or Taiwan's Personal Data Protection Act Article 27.

Enterprises typically apply ISO 27002 as a practical guide for implementing or strengthening their ISO 27001-compliant ISMS. The application steps include: 1. Risk Assessment and Treatment: Following ISO 27001, identify information assets, potential threats, and vulnerabilities, then assess risk levels. Refer to ISO 27002 controls (e.g., A.5.7 "Threat intelligence" or A.8.24 "Web filtering" for cyberattack risks) to select and implement appropriate measures to mitigate identified risks. 2. Control Implementation: Develop detailed policies, procedures, and technical configurations based on the chosen ISO 27002 controls. For example, to protect customer personal data, implement A.8.12 "Data leakage prevention" and A.8.16 "Monitoring activities." 3. Monitoring, Review, and Improvement: Regularly monitor the effectiveness of controls, conduct internal audits and management reviews, and continuously improve the ISMS based on the results. Companies implementing ISO 27001/27002 often report a 20-30% improvement in compliance rates and a 10-15% reduction in security incidents, enhancing their ability to pass regulatory audits.

Taiwan enterprises often encounter several challenges when implementing ISO 27002: 1. Resource Constraints: Small and Medium-sized Enterprises (SMEs) may lack sufficient budget, human resources, and expertise for comprehensive security control implementation. To overcome this, prioritize high-risk areas, implement critical controls in phases, and consider external consulting to optimize resource utilization. 2. Integration with Local and International Regulations: Taiwanese companies must comply with local laws like the Personal Data Protection Act and the Cyber Security Management Act, alongside international standards like ISO 27002. The solution is to establish an integrated compliance framework that maps local regulatory requirements to ISO 27002 controls, ensuring a single management system addresses multiple compliance needs. 3. Insufficient Employee Security Awareness: Many security incidents stem from human error. This challenge can be addressed through regular security awareness training and drills, embedding a security culture into daily operations. For instance, simulating phishing attacks can enhance employee understanding and practice of A.6.3 "Information security awareness, education and training." This can lead to a significant improvement in employee security posture within 6-12 months.
