Introduction
When systems slow down, users get creative and that’s when mistakes and security shortcuts happen.
ISO 27001 Control 5.47 Capacity Management ensures your organization’s IT resources are always sufficient to meet business and security needs.
Because performance issues aren’t just an inconvenience they can become vulnerabilities.
Why This Control Matters
Every system has limits CPU, memory, bandwidth, storage, or licenses. When those limits are exceeded, availability drops, security tools fail to run properly, and monitoring systems miss critical alerts.
Control 5.47, from ISO/IEC 27002:2022 Section 5.47, is an Organizational and Technical control that’s preventive in nature.
It supports Availability and Integrity through the Monitor, Plan, and Protect cybersecurity concepts.
Capacity management isn’t just about speed it’s about resilience.
What This Control Involves
Monitor System Performance
Track CPU, memory, disk, and network usage continuously.
Use dashboards and automated alerts for thresholds.
Forecast Future Needs
Analyze trends to predict when resources will run out or need expansion.
Include Capacity in Change Management
Assess capacity impact before new deployments or upgrades.
Maintain Redundancy and Scalability
Use load balancing, auto-scaling, or cloud elasticity to prevent outages.
Document and Review Regularly
Keep records of capacity plans, utilization reports, and scaling strategies.
Common Pitfalls
- 🚫 Reactive scaling only upgrading when something breaks
- 🚫 Ignoring resource monitoring for cloud or hybrid systems
- 🚫 No link between business growth and IT resource planning
- 🚫 Lack of communication between IT, DevOps, and management
