Guide to Threat Modeling - CISSP Software Development Security

What is Threat Modeling?
Threat modeling is a process in which potential threats, such as structural vulnerabilities or the absence of appropriate safeguards, can be identified, enumerated, and prioritized – all from a hypothetical attacker’s point of view.

Why is Threat Modeling Important?
Threat modeling helps in identifying the potential threats and vulnerabilities at the early stages of the software development lifecycle (SDLC). This enables the organization to mitigate these risks before the software goes live, thereby saving costs and avoiding potential damage.

How Threat Modeling works?
Threat modeling involves four key steps: Identifying security objectives, Application decomposition, Identification of threats, and Identification and implementation of countermeasures.
