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
