What are the 7 steps of a standard security risk assessment model?

How to perform an ISO 27001 security Risk assessment

Protecting sensitive data requires more than basic antivirus software—it demands a structured framework. A standard ISO 27001 risk assessment provides a clear roadmap to identify vulnerabilities and safeguard critical assets effectively.

The process begins by defining your risk assessment methodology. Establishing clear criteria upfront ensures your evaluation remains consistent and repeatable. Once the rules are set, you need to identify and catalogue your information assets, mapping out where data resides and which systems keep your operations running.

Next, look closely at potential external and internal hazards to identify threats and vulnerabilities. After mapping these entry points, move on to evaluate risks by measuring the likelihood of an exploit against its potential financial or operational impact. This clarity allows you to prioritize high-risk areas over minor issues.

With priorities established, you must determine risk treatment options. Depending on the scenario, you might choose to mitigate, accept, transfer, or avoid the risk altogether. To maintain compliance and clear accountability, you then need to compile essential risk documentation, including a Risk Treatment Plan and Statement of Applicability.

Finally, security is not a set-it-and-forget-it project. You must regularly review, monitor, and improve your framework as new security threats evolve and business operations scale.
