ISO/IEC 27001 FAQ Risk Acceptance

Clause 6.1.2 requires the risk-assessment process to establish and maintain risk acceptance criteria. The organization identifies risks associated with loss of confidentiality, integrity, and availability within the ISMS scope, identifies risk owners, analyses consequence and realistic likelihood, determines risk levels, compares the results with its criteria, and prioritizes risks for treatment.

Clause 6.1.3 then requires appropriate treatment options, all necessary controls, comparison with Annex A, a Statement of Applicability, and a treatment plan. The risk owners approve that plan and accept the residual information security risks. The standard does not prescribe one scoring scale, approval form, or universal monetary threshold.

ISO/IEC 27001 requires documented information about the risk-assessment and risk-treatment processes and their results, but it does not prescribe a risk-acceptance form. The record should let another reviewer understand the scoped risk scenario, affected information or process, confidentiality-integrity-availability impact, criteria used, likelihood and consequence rationale, current controls, chosen treatment, residual-risk result, and owner approval.

Link the accepted residual risk to the risk-treatment plan and the Statement of Applicability where controls are involved. An acceptance entry that conflicts with an SoA implementation status or an overdue treatment needs correction or explicit reconciliation.

ISO/IEC 27001 assigns approval of the risk-treatment plan and acceptance of residual information security risk to risk owners. Security or compliance teams may coordinate the assessment, challenge the evidence, and administer the register, but they should not approve risk on behalf of an unnamed business owner.

The organization should define authority levels for different risk levels. That governance model is an organizational design choice; the standard's fixed point is that the risk owner is identified and provides the required approval and acceptance. A committee may supply escalation or collective governance, but the record should still show the identified risk owner and the authority used for the decision.

Clause 8.2 requires information security risk assessments at planned intervals and when significant changes are proposed or occur. Apply that rule to accepted risks rather than treating the approval as permanent.

A significant incident, threat change, control failure, new vulnerability, supplier change, scope change, or changed legal or contractual requirement may invalidate the earlier decision. Whether a change is significant depends on the organization's maintained criteria and the facts; record that assessment rather than treating every change as an automatic new acceptance.
