What is a Risk Assessment?
A cybersecurity risk assessment is a systematic process for identifying, analyzing, and evaluating information security risks. It forms the foundation of any security management system and drives decision-making about security investments and priorities.
Process Steps
- Context establishment: Define scope, criteria, and risk appetite
- Risk identification: Identify assets, threats, vulnerabilities, and existing controls
- Risk analysis: Determine likelihood and impact of identified risks
- Risk evaluation: Compare risk levels against acceptance criteria
- Risk treatment: Select and plan appropriate risk treatment options
Risk Treatment Options
- Mitigate: Implement controls to reduce risk to acceptable levels
- Transfer: Share risk through insurance or contractual arrangements
- Accept: Formally accept risks within the organization's risk appetite
- Avoid: Eliminate the risk by removing the source or changing plans
Standards Context
Risk assessment is a core requirement of ISO 27001, TISAX, IEC 62443, and virtually all cybersecurity frameworks. Each standard may prescribe specific methodologies or criteria for conducting assessments.
