Threat modelling is a systematic approach to identifying and addressing potential security threats and vulnerabilities in a system or network. The process involves analyzing the system, understanding potential risks, and devising countermeasures to mitigate or prevent those risks. The key steps in threat modeling typically include defining assets, understanding how applications interact with those assets, creating security profiles for applications, identifying potential threats, prioritizing those threats, and documenting actions taken to address them.
Threat modeling is like creating a blueprint for securing a system. Its purpose is to identify potential risks and vulnerabilities in a system, understand how they could be exploited, and then come up with ways to prevent or minimize the impact of those threats.
Purpose of threat modelling :
- Early Detection of Threats:
- Why: To catch and understand potential problems before they can cause harm.
- How: By analyzing the system and figuring out what could go wrong (threats) and where it might be vulnerable.
- Effective Communication:
- Why: To ensure that everyone involved understands the risks and the plan to mitigate them.
- How: By providing a structured way for security experts and stakeholders to discuss and agree on potential threats and countermeasures.
