ISO 27001 A.8.6 Capacity Management Checklist
Capacity Management, as outlined in ISO 27001:2022 under control A.8.6, is a fundamental component of an organisation’s Information Security Management System (ISMS). This control ensures that IT infrastructure, systems, and services can handle both current and future operational demands, maintaining system performance and preventing disruptions.
Effective capacity management aligns with business continuity, strategic growth, and compliance objectives, optimising resource use and supporting long-term planning.

Why Should You Comply With Annex A.8.6? Key Aspects and Common Challenges
1. Monitoring
Key Aspect: Continuous tracking of IT resources’ performance and utilisation, including servers, storage, networks, and applications.
Common Challenges:
- Data Overload: Managing vast data volumes from monitoring tools can overwhelm systems and staff.
- Integration: Difficulties in integrating diverse monitoring tools across various systems.
Solutions:
- Implement centralised dashboards to aggregate and filter key data, making it accessible and actionable.
- Use automated alert systems to notify relevant personnel of potential capacity issues.
- Standardise protocols and APIs for seamless integration of monitoring tools, enhancing system interoperability.
Related ISO 27001 Clauses: Regular monitoring and measurement (9.1), internal audit (9.2), management review (9.3).
2. Planning
Key Aspect: Forecasting future resource needs based on business growth, new projects, and technological advancements.
Common Challenges:
- Predictive Accuracy: Accurately forecasting capacity requirements amidst unpredictable changes.
- Budget Constraints: Balancing the need for future capacity with financial limitations.
Solutions:
- Utilise predictive analytics and historical data to enhance forecasting accuracy.
- Develop flexible budgeting models to accommodate varying capacity demands.
- Regularly review and adjust capacity plans based on real-time data and business priorities.
Related ISO 27001 Clauses: Risk assessment (6.1.2), risk treatment (6.1.3), objective setting (6.2).
3. Scalability
Key Aspect: Ensuring systems can scale efficiently to handle increased workloads.
Common Challenges:
- Legacy Systems: Older systems may not support easy scalability.
- Technical Debt: Accumulated technical debt can hinder scalability.
Solutions:
- Prioritise modernising legacy systems with scalable architectures, such as cloud-based or modular infrastructure.
- Implement phased approaches to reduce technical debt, focusing on critical areas.
- Leverage cloud computing for elastic scaling, allowing resources to adjust based on demand.
Related ISO 27001 Clauses: Change management (8.1), continual improvement (10.1), risk treatment plan (6.1.3).
4. Efficiency
Key Aspect: Optimising resource use to prevent both underutilisation and overprovisioning.
Common Challenges:
- Resource Optimisation: Balancing resource efficiency with redundancy needs.
- Changing Workloads: Adapting to dynamic and unpredictable workloads.
Solutions:
- Implement dynamic resource allocation strategies based on real-time demand.
- Use virtualisation and containerisation to maximise hardware utilisation and flexibility.
- Conduct regular efficiency audits to identify and eliminate waste, optimising resource allocation.
Related ISO 27001 Clauses: Operational planning and control (8.1), monitoring and measurement (9.1), continual improvement (10.1).
