Introduction to Threat Modelling

Threat modeling is a process that involves analyzing a system to identify weaknesses stemming from suboptimal design choices. Its primary goal is to identify these weaknesses early in the system's lifecycle, allowing for corrective actions before implementation or deployment solidifies these issues. This conceptual exercise helps in understanding which aspects of a system's design should be altered to minimize risks to an acceptable level for its stakeholders. It involves examining the system's components, their interactions with the external environment, and potential actors that might interact with these systems. By envisioning how these elements could fail or be compromised, threat modeling identifies possible threats, leading to system modifications for better resistance against these threats【7†source】.

Main Functions of Threat Modelling

  • Cyclic Activity of Analysis and Modification

    Example Example

    Identifying system vulnerabilities

    Example Scenario

    In a financial software system, threat modeling might identify a vulnerability in transaction processing, leading to modifications in the system to strengthen security measures.

  • Identification of Weaknesses in System Design

    Example Example

    Improving system architecture

    Example Scenario

    For a cloud storage service, threat modeling could reveal weaknesses in data encryption processes, prompting a redesign for enhanced data protection.

  • Preventive Action Against Potential Threats

    Example Example

    Proactive security measures

    Example Scenario

    In an IoT-based home security system, threat modeling might uncover potential hacking vulnerabilities, leading to the development of stronger authentication protocols before deployment.
