Learn About Threat Modelling

What is Threat Modelling?

Threat modelling is a structured approach to identifying, quantifying, and addressing security risks in a system. It helps teams think like attackers to find vulnerabilities before they're exploited.

Why Threat Model?

Threat modelling early in development is far cheaper than fixing vulnerabilities in production. It improves security awareness across teams and helps prioritize security investments based on actual risk.

The STRIDE Framework

  • Spoofing - Impersonation attacks
  • Tampering - Data modification
  • Repudiation - Denying actions
  • Information Disclosure - Data leaks
  • Denial of Service - Availability attacks
  • Elevation of Privilege - Unauthorized access

Key Concepts

  • Assets - What you're protecting (data, systems)
  • Trust Boundaries - Where security controls apply
  • Threat Actors - Who might attack (insiders, hackers)
  • Attack Surface - Entry points for attackers
