ISO 27001 Risk Assessment Spreadsheet Template

This is a structured breakdown of a typical ISO 27001 risk assessment spreadsheet. You can use this as a guide to build your own using a tool like Google Sheets or Microsoft Excel. It follows the requirements of the ISO 27001 standard by guiding you through the identification, analysis, and treatment of risks.

Risk Management Framework
This sheet defines the rules for your risk assessment.

Risk Criteria - Impact

Define your scale for measuring impact (e.g., 1-5, or Low/Medium/High/Critical). Provide clear descriptions for each level based on potential damage to confidentiality, integrity, and availability.

Risk Criteria - Likelihood

Define your scale for measuring likelihood (e.g., 1-5, or Rare/Unlikely/Possible/Likely/Almost Certain). Provide clear descriptions for each level.

Risk Matrix

A matrix (e.g., a 5x5 grid) that combines your Likelihood and Impact scores to generate a Risk Score. This visual tool helps you classify risks (e.g., green for low, yellow for medium, red for high).

Risk Acceptance Criteria

Define the threshold at which a risk is considered 'unacceptable' and requires treatment (e.g., any risk with a score of 15 or higher).

Risk Owners

List the key stakeholders responsible for risk management (e.g., CISO, IT Manager, Head of Operations).

Scope of ISMS

A clear definition of what your Information Security Management System (ISMS) covers.
