ISO/IEC 27005 FAQ Risk Owners

A risk owner is the person or entity with accountability and authority to manage a risk. Assign the role to someone who understands the issue, can make informed treatment and acceptance decisions, and can direct or escalate action.

The standard supplies guidance rather than a mandatory scoring model, legal rule, or standalone certification scheme.

Overview

Assign every identified risk to a as part of the assessment. The owner can be a person or a defined body, but the record should show who holds the authority, how decisions are made, and where the risk is escalated. An analyst, asset owner, or control owner is not automatically the risk owner.

Question 1

Who should be the risk owner under ISO/IEC 27005?

ISO/IEC 27005:2022 defines a as a person or entity with accountability and authority to manage a risk. The owner should understand the issue and be able to make informed decisions about treatment. The person's position should allow that authority to be exercised in practice.

Possible owners include top management, a security committee, process owners, functional owners, department managers, and asset owners. These are examples, not automatic assignments. Choose the owner from the risk's business consequence, organizational location, and level, then define escalation where the exposure exceeds that owner's authority.

  • Assign the risk, not merely the asset or control, and identify the affected business objective.
  • Separate the from analysts and treatment owners unless one person genuinely has all of those roles and authorities.
  • For a committee owner, name the body, chair or accountable role, quorum or decision rule, and escalation route.
  • Example: an asset owner can own a risk when that role can understand the business exposure and authorize treatment. If the role can only maintain the asset, assign the risk to the process, function, department, committee, or management level that can make and fund the decision.

Who should be a under ISO/IEC 27005?

Assign each identified risk to a person or entity that is accountable for and has authority to manage that risk, understands the issue, and can make informed treatment decisions. Top management, a security committee, a process or functional owner, a department manager, or an asset owner can qualify, but no job title qualifies automatically.

Is the asset owner automatically the ?

No. An asset owner can be the only when the role has the required understanding, accountability, and authority for the specific risk. Ownership should follow the affected objective, business consequence, organizational location, and risk level, with escalation where the decision exceeds the role's authority.

Can a committee be the ?

Yes. ISO/IEC 27005 allows an entity such as a security committee to own risk. The record should identify the committee, its authority, how it reaches a decision, who communicates or records that decision, and where the risk goes when it exceeds the committee's mandate.

What decisions remain with the ?

The manages the assigned risk, approves the risk treatment plan, and decides whether is acceptable within delegated authority. Analysts can assess the risk and treatment or control owners can implement measures, but those tasks do not transfer the risk owner's accountability.

Question 2

What evidence should support the risk-owner assignment?

The risk record should identify the risk, owner, organizational role, assignment date, authority, acceptance threshold or risk class, required approvals, delegated treatment powers, contributors, treatment owners, escalation route, and review trigger. Record why this owner can understand and manage the specific exposure.

  • Use organization charts, role descriptions, delegations of authority, committee terms, process and asset ownership, and acceptance criteria to verify the assignment.
  • Keep the owner's approval of the treatment plan and decision on residual-risk acceptance with the risk record.
  • Record temporary cover and handover when personnel change; do not leave a risk assigned to a departed or inactive owner.

ISO/IEC 27005:2022 Clauses 6.4.2, 7.2.2, and 8.6 connect risk ownership to delegated acceptance authority, treatment-plan approval, residual-risk decisions, and personnel changes.

Question 3

What does the risk owner decide, and what can be delegated?

The manages the assigned risk, approves the treatment plan, and decides whether is acceptable within delegated authority. Analysts can prepare assessments and treatment owners can implement controls, but those tasks do not transfer the owner's accountability.

  • Top management remains accountable for assigning authority, responsibility, and resources at appropriate levels.
  • Escalate acceptance decisions that exceed the owner's threshold or fall into a class reserved for higher management.
  • Use two-way communication so owners receive evidence and implementation status before approving treatment or accepting .

ISO/IEC 27005:2022 Clauses 8.6, 10.2, and 10.3 describe top-management accountability, risk-owner approval and acceptance, and communication with implementation staff.

Question 4

When should risk owners be reviewed?

Review ownership when personnel, organizational boundaries, process or asset ownership, risk level, scope, or delegated authority changes. Also review it when the owner cannot direct treatment, obtain resources, or make the required decision.

  • Trigger reassignment during role changes, reorganizations, mergers, outsourcing, or transfers of a business process or asset.
  • Check that committee ownership still has a functioning decision process and named escalation path.
  • Preserve the previous owner, handover date, open treatment actions, accepted conditions, and new approval.

ISO/IEC 27005:2022 Clause 7.2.2 explicitly identifies personnel change in the relevant business area as a trigger for identifying risk owners.
