Threat Modelling Process

What is it?

Threat modelling is a structured exercise to anticipate, identify, and prioritise potential cyber threats to an organisation’s assets, systems, and data. By understanding how attackers might operate, teams can make more informed decisions, strengthening defences where they are most needed and reducing the odds of a successful breach.


What could happen?

Without a proper threat modelling process, security efforts may rely on guesswork. Critical vulnerabilities can remain unnoticed, allowing attackers to exploit them. Misaligned defences can waste resources and fail to protect what truly matters. Over time, this reactive approach invites regulatory scrutiny, erodes customer trust, and increases financial liabilities.


What to do about it?

Foundational: Conduct a basic threat brainstorming session with your security and development teams to identify common risks and vulnerabilities in key systems.
Outcome: Establishes a foundational understanding of likely threats and improves team awareness.

Enhanced: Adopt a formal threat modelling methodology (e.g., STRIDE, PASTA) and use automated tools to identify, categorise, and prioritise threats against critical applications or workflows.
Outcome: Provides a repeatable, data-driven approach for focusing remediation efforts on the most pressing risks.

Comprehensive: Integrate threat modelling into your Software Development Lifecycle (SDLC) and continuously update models to reflect changes in the environment, emerging threat intelligence, and evolving business processes.
Outcome: Ensures proactive risk management and sustained security improvements over time.
