Introduction
The ISO 27001 Risk ownership model defines how Information Security Risks are assigned managed & monitored within an Organisation. It requires clear accountability where specific Individuals own specific Risks & ensure controls remain effective. This model supports compliance with the Information Security Management System [ISMS] standard published by the International organisation for Standardization [ISO]. By linking Risks to accountable roles the ISO 27001 Risk ownership model strengthens Governance improves decision making & aligns security actions with Business Objectives.
Understanding Risk Ownership in ISO 27001
At its core the ISO 27001 Risk ownership model is about responsibility. A Risk owner is the Person accountable for managing a defined Information Security Risk. This includes understanding the Risk approving treatment options & ensuring controls operate as intended.
ISO 27001 does not dictate job titles. Instead it focuses on clarity. A Risk owner must have authority resources & knowledge to act. This approach mirrors how a building owner maintains safety systems rather than leaving decisions to random occupants.
Authoritative guidance from the ISO Standard is supported by public resources such as

Core Roles Within the Risk Ownership Model
Risk Owner
The Risk owner accepts accountability for a specific Risk. This role ensures Risk Treatment Plans are appropriate & reviewed regularly.
Control Owner
In some Organisations control owners manage specific safeguards such as Access Control or backup processes. They report performance to the Risk owner.
Top Management
Leadership provides oversight & ensures Risk ownership aligns with Business priorities. This requirement reinforces Governance as described by

How the ISO 27001 Risk Ownership Model Works in Practice?
The ISO 27001 Risk ownership model begins during Risk Assessment. Identified Risks are documented evaluated & assigned to owners. Each owner decides whether to mitigate transfer avoid or accept the Risk.
This process works like a relay race. The Assessment identifies the baton the assignment hands it over & ownership ensures it reaches the finish line without being dropped.
Documentation plays a central role. Risk registers treatment plans & review records demonstrate accountability during audits. Practical examples of structured ownership can be found in guidance from
https://www.enisa.europa.eu/topics/Risk-management.
Benefits & Limitations of the Model
The ISO 27001 Risk ownership model improves accountability & transparency. Decisions become faster because ownership is clear. Audit readiness also improves because Evidence links Risks to responsible roles.
However limitations exist. Assigning ownership without authority weakens the model. Overloading one Individual with too many Risks also reduces effectiveness. The model depends on management support & regular review.

Conclusion
The ISO 27001 Risk ownership model transforms Risk Management from a theoretical exercise into a practical system of accountability. By assigning clear ownership Organisations strengthen control oversight & align Information Security with operational reality.
