The PDCA cycle in the ISO 27001 Standard
The Deming Cycle, also known as the PDCA (Plan, Do, Check, Act) cycle, is a continuous improvement approach that can be applied in various areas, including information security management in the context of the ISO standard. 27001, let’s see below how it focuses on the different stages:
- Plan (P): At this stage, the organization must plan its information security management system (ISMS) in accordance with the requirements of ISO 27001. This includes the identification of information assets, risk assessment, the definition of security policies and objectives, and the planning of security controls. It is important to establish a solid foundation for the ISMS.
- Do (D): Once the ISMS has been planned, it moves on to implementation. This involves executing plans, implementing security controls, training staff, and creating necessary records and documentation. During this phase, the organization puts into practice what it has planned.
- Check (C): In this stage, an evaluation and monitoring of the ISMS is carried out to ensure that it is functioning in accordance with the established policies and procedures. This involves conducting internal audits, measuring information security performance, and continuously assessing risks.
- Act (A): Based on the results of the Verify phase, the organization takes measures to correct and improve the ISMS. This may include implementing corrective and preventive actions, updating policies and procedures, and introducing continuous improvements to the system.
The Deming Cycle is repeated continuously to achieve continuous improvement in information security management. Each time the cycle is completed, feedback is given to make additional adjustments and improvements to the ISMS in accordance with changes in the threat environment, technological advances and organizational requirements. This continuous improvement methodology is essential to maintain the effectiveness and relevance of the ISMS over time, which is essential to meet the objectives of ISO 27001.
