Threat Modeling
Understand the Threat. Strengthen the Design.
Identify potential cybersecurity weaknesses before they become harder to address. MedSec combines structured threat modeling methodology with medical device expertise to help manufacturers examine attack paths, evaluate feasible threats, and inform security risk management decisions.
Knowing Where to Look Is the Hard Part
Medical devices are increasingly connected to applications, cloud services, wireless networks, and complex clinical workflows. Each connection can introduce potential attack paths that are difficult to identify when components are assessed individually.
Effective threat modeling goes beyond identifying interfaces or completing a checklist. It requires understanding how an adversary might exploit a device's architecture, cross trust boundaries, compromise critical assets, or create patient safety concerns.
MedSec helps manufacturers identify those possibilities while there's still time to inform design and risk management decisions.
A Structured Approach to Medical Device Threat Modeling
MedSec works collaboratively with manufacturer engineering and security teams to examine the device as designed, identify feasible threats, and document potential mitigations.
01
Understand the Architecture
Review hardware, software, communications, critical assets, security controls, and relevant safety information.
02
Develop Architecture Views
Examine global system architecture, patchability, multi-patient harm, and security-relevant use cases.
03
Identify Feasible Threats
Apply STRIDE-per-element analysis to identify realistic threat events, attack paths, and potential design weaknesses.
04
Document Findings
Develop a structured Threat Model Report with feasible threat events and potential mitigations to inform manufacturer risk decisions.
