In this article we lay bare ISO27001 Clause 8.3 Information Security Risk Treatment. Exposing the insider trade secrets, giving you the templates that will save you hours of your life and showing you exactly what you need to do to satisfy it for ISO27001 certification. We show you exactly what changed in the ISO27001:2022 update. I am Stuart Barker the ISO27001 Ninja and this is ISO27001 Clause 8.3

What is ISO27001 Clause 8.3 Information Security Risk Treatment?

The ISO27001 standard requires an organisation to treat risks and to keep evidence of the results.

ISO27001 Clause 8.3 is all about risk treatment.

Where we covered the risk treatment planning in ISO27001 Clause 6.1.3 here we look at the execution.

The ISO27001 standard for ISO27001 certification wants you to effectively treat and manage risks.

That risk treatment process has to maintain evidence of the risk treatment which is done by using a risk register.

What are the ISO27001:2022 Changes to Clause 8.3?

Great news. There are no changes to ISO27001 Clause 8.3 in the 2022 update.

ISO27001 Clause 8.3 Definition

The ISO27001 standard defines ISO27001 clause 8.3 as:

The organisation shall retain documented information of the results of the information security risk treatment.

ISO27001 Clause 8.3 Risk Treatment Examples

Risk treatment examples include:

• You can accept the risk. You would hold a management review meeting, get agreement to accept the risk, minute the meeting to document the decision and update the risk register.

• You could transfer the risk. Whilst you cannot transfer the accountability for a risk you can transfer the treatment of the risk. An example of this would be having insurance in place or outsourcing to a third party.

• You could mitigate the risk. The level of mitigation may be to reduce but not eliminate the risk or to eliminate the risk. It really depends on the risk appetite of the organisation.

ISO27001 Clause 8.3 Implementation Guide

To meet the requirement of ISO27001 clause 8.3 you must evidence that the risk treatment plan that you described in ISO27001 Clause 6.1.3 is being implemented. The way that you do this is by having effective risk management in place, using a risk register that includes all of the required controls and includes residual risk and then ensuring that the risk register is shared with, and minuted at, the management review team meeting.

The controls that you selected in the Statement of Applicability are all designed to effectively manage risk.

You ensure that you can tie your risk register and your risk treatment to the controls that you have, including those you choose in the Statement of Applicability.

How to conduct an ISO27001 risk treatment

You use the risk register and sure that you provide an effective risk rating for each risk.

Using your risk treatment plan you will have identified the relevant risk treatment based on risk level.

This can be overridden by the management review team meeting.

For each risk that you identify, once you have identified the risk treatment implement the treatment you have chosen. If this is to either introduce or enhance controls, including those in the Statement of Applicability, follow your continual improvement process.

Once the risk treatment is implemented update the risk register and conduct and audit of the risk again and record the residual risk score.

This is the new risk score based on the new risk treatment.

Ideally the risk score will have gone down.

You would not want to implement a control for a risk that did not positively impact its risk score and go some way to mitigating it.

ISO27001 Clause 8.3 Templates

ISO27001 templates are a great way to implement your information security management system. Whilst an ISO27001 toolkit can save you up to 30x in consulting fees and allow you to deliver up to 10x faster these individual templates help meet the specific requirements of ISO27001 clause 8.3.
