ISO 27002 Information security controls

ISO/IEC 27002 is an international standard providing a code of practice for information security controls. It is not a certifiable standard itself but serves as a crucial companion to the ISO 27001 standard for Information Security Management Systems (ISMS). It offers detailed implementation guidance for the controls listed in ISO 27001 Annex A. The 2022 version structures 93 controls into four themes: Organizational, People, Physical, and Technological. In risk management, after an organization identifies and evaluates risks according to ISO 27001, it uses ISO 27002 to select and implement appropriate controls. This framework is vital for meeting the requirements of regulations like GDPR Article 32 ('Security of processing') by providing a globally recognized set of best practices.

ISO 27002 is applied after a risk assessment to translate risk treatment plans into concrete actions. Key implementation steps include: 1. **Control Selection & Statement of Applicability (SoA)**: Based on risk assessment results, select relevant controls from the 93 provided in ISO 27002 and document the justification for their inclusion or exclusion in the SoA. 2. **Control Design and Implementation**: Use the standard's guidance to develop specific policies, processes, and technical configurations. For control 5.23 'Information security for use of cloud services,' this means creating a cloud security policy and a vendor assessment process. 3. **Effectiveness Measurement and Improvement**: Establish Key Performance Indicators (KPIs) to monitor control performance, such as aiming for a 95% patch rate for vulnerabilities identified under control 8.8 'Management of technical vulnerabilities.' A global logistics company reported a 35% reduction in security incidents after aligning its controls with ISO 27002.

Enterprises in Taiwan often face three primary challenges when implementing ISO 27002: 1. **Resource Constraints**: Small and medium-sized enterprises (SMEs) may lack the dedicated cybersecurity staff and budget to implement all controls. The solution is to adopt a risk-based approach, prioritizing controls that mitigate the highest risks, and consider outsourcing to a Managed Security Service Provider (MSSP). 2. **Regulatory Mapping**: Difficulty in aligning ISO 27002 controls with local regulations like the Cybersecurity Management Act. This can be overcome by creating a compliance matrix that maps each control to specific legal articles, ensuring efficient, dual-purpose compliance efforts. 3. **Weak Security Culture**: Technical controls can be undermined by human error, such as falling for phishing attacks. To counter this, implement a continuous security awareness program as guided by control 6.3, including regular phishing simulations with a clear goal, such as reducing the employee click-rate by 50% within six months.
