Threat Modelling allows organisations to understand exactly where systems fit within the context of an organisation, how these systems affect the overall security posture and the systems attack-surface. Overall, these modelling exercises succeed in improving network security through the identification and combination of security vulnerabilities, business objectives, and defining relevant countermeasures to mitigate threats as part of a kill-chain identification exercise.
The primary output from a threat modelling exercise is the interactive diagram that can be updated and modified over time as threats and systems change. Following this a list of verified and testable assumptions that is bespoke to your organisation and environment. Each given system will also have a prioritised list of threats including both technical vulnerabilities alongside organisational risks.
All these results combined are presented with the actions required to validate and re-validate the findings to allow seamless handover to the internal team. The aim of threat modelling is not to simply provide a static diagram, but to arm your technology and security team with the tools and information needed to continually improve the cybersecurity posture of your organisation.
