About This Template

The spreadsheet implements a structured risk assessment methodology aligned with ISO 27001:2022 Clause 6.1.2 and ISO 27005 guidance. It walks you through the complete risk assessment lifecycle: asset identification, threat identification, vulnerability assessment, likelihood and impact scoring, risk level calculation, risk treatment decisions (mitigate, accept, transfer, avoid), and control selection with mapping to ISO 27001:2022 Annex A controls. The scoring system uses a clear 5x5 matrix with defined criteria for each likelihood and impact level, eliminating the subjectivity that often undermines risk assessment quality.

What makes this template particularly valuable is the pre-populated threat catalog. Rather than starting from scratch, you begin with a comprehensive list of common information security threats relevant to technology companies - from ransomware and phishing to cloud misconfiguration and insider threats - and assess which are relevant to your organization. This approach ensures thoroughness while saving significant time. The template also includes a risk treatment plan worksheet that links directly to your risk register, creating a clear audit trail from identified risks through treatment decisions to implemented controls. This traceability is exactly what auditors look for during certification assessments.

Frequently Asked Questions

What risk assessment methodology does this template use?
The template uses a qualitative risk assessment methodology based on ISO 27005 guidance, with a 5x5 likelihood-impact matrix. Likelihood is assessed on a scale from Very Low (annual or less) to Very High (daily/weekly occurrence). Impact is assessed from Negligible to Critical based on financial, operational, reputational, and regulatory consequences. This methodology satisfies ISO 27001 auditor expectations while remaining practical for organizations without dedicated risk management teams.
How often should I update the risk assessment?
ISO 27001 requires risk assessments to be repeated at planned intervals or when significant changes occur. Most organizations conduct a comprehensive review annually and perform targeted updates when major changes happen - new systems, organizational restructuring, new threats, or significant incidents. The template is designed for easy updates so you can maintain it as a living document rather than a one-time exercise.
Can I use this template if I have never done a risk assessment before?
Yes. The template includes a methodology guide that walks you through each step of the risk assessment process. The pre-populated threat catalog means you do not need to identify threats from scratch - you evaluate which pre-listed threats are relevant to your organization and assess their likelihood and impact. This guided approach makes the template accessible even for first-time risk assessors.
Will an auditor accept this risk assessment format?
The template is designed to meet ISO 27001 certification audit requirements. It includes all the elements auditors look for: a defined methodology, asset identification, threat and vulnerability analysis, risk scoring with clear criteria, risk treatment decisions, control mapping, and management acceptance of residual risks. Many organizations have used similar formats successfully in certification audits.
