ISO 27001:2022 Annex A Control 8.6
Abstract of Annex A Control 8.6: Capacity management
ISO 27001 Annex A Control 8.6 focuses on the efficient management of organizational resources to meet current and future capacity needs. It establishes that systems, personnel, and facilities are monitored and adjusted to prevent capacity-related issues, thereby maintaining operational integrity and availability.

Objective of Control 8.6
The primary objective of Control 8.6 is to maintain sufficient capacity for critical business processes, systems, and resources. This involves ensuring that your organization’s infrastructure can support both regular operations and peak loads without compromising performance or security. via addressing capacity requirements proactively, you can prevent bottlenecks, reduce operational risks, and avoid disruptions.
Purpose of Control 8.6
The purpose of this control is to:
- Ensure the availability and efficiency of information processing facilities and other organizational resources.
- Proactively address resource limitations that could impact business-critical operations.
- Identify and mitigate risks related to over-utilized or under-utilized resources.
Concepts in Capacity Management
Monitoring Resource Utilization
Your organization should continuously track resource usage, such as processing power, storage, network bandwidth, and human resources. This monitoring helps identify trends and potential issues before they impact operations.
Proactive Adjustments
Align your resources to meet changing demands through:
- System tuning
- Upgrading infrastructure
- Allocating additional personnel
Stress Testing
Regular stress tests ensure your systems can handle peak demands and unexpected surges. These tests help identify vulnerabilities and guide resource planning.
Documentation
Developing a documented capacity management plan is essential for mission-critical systems. This plan should outline resource requirements, monitoring practices, and contingency measures.
Strategies for Capacity Management
Increasing Capacity
To address growing demands, consider:
- Hiring additional personnel: Ensure you have the human resources to support key operations.
- Acquiring new facilities: Expand physical or virtual spaces to accommodate growth.
- Upgrading systems: Invest in more powerful hardware, memory, or storage solutions.
- Leveraging cloud computing: Use the scalability and elasticity of cloud-based services to dynamically adjust resource availability.
Reducing Demand
Optimizing resource usage can be just as effective as increasing capacity. Strategies include:
- Deleting obsolete data: Free up storage by removing outdated information.
- Disposing of old records: Clear physical space by securely disposing of hardcopy files past their retention period.
- Decommissioning systems: Retire unused applications or databases.
- Optimizing code: Improve the efficiency of software and database queries.
- Restricting bandwidth: Limit non-critical services like video streaming.
Detective and Preventive Controls
Preventive measures, such as proactive planning and regular system tuning, can help avoid disruptions. These controls ensure your organization remains resilient and operational. Detective controls play a critical role in identifying capacity issues early. Implement systems to:
- Monitor utilization thresholds.
- Trigger alerts when critical limits are approached.
Future-Proofing Capacity Requirements
Forecasting is essential for effective capacity management. To future-proof your resources:
- Analyze current trends and project future needs.
- Factor in organizational growth and technological advancements.
- Account for long procurement lead times and high-cost items in your planning.
Related ISO 27001 Controls
Several ISO 27001 controls complement the objectives of Control 8.6:
- Control 5.4: Establishes clear roles and responsibilities for managing resources.
- Control 5.23: Focuses on cloud security, supporting capacity management in cloud environments.
- Control 7.2: Addresses the physical security of facilities.
Templates Supporting Control 8.6
To support the implementation of ISO 27001 Control 8.6, the following templates from Cyberzoni.com can help:
- Capacity Management Plan Template: Document strategies and processes for resource planning.
- Cloud Security Policy Template: Manage cloud elasticity and scalability effectively.
- Incident Response Plan Template: Address capacity-related disruptions efficiently.
Capacity Management and Cloud Computing
Cloud computing offers inherent advantages for capacity management. With its scalability and elasticity, cloud services enable your organization to:
- Expand resources dynamically during peak demands.
- Reduce costs by scaling down during low usage periods.
- Simplify infrastructure management through automated provisioning.
Implementing cloud-based solutions aligns with the recommendations of ISO/IEC TS 23167 and can significantly enhance your capacity management capabilities.
