- Requirements Definition
We begin by defining project requirements — a concise description of what you want to achieve. At this stage we clarify technical constraints and ask the right questions.
- Threat Modeling
Before designing the system architecture we perform device threat modeling. We identify realistic attack vectors such as firmware extraction, device cloning, debug interface access, backend impersonation, and unauthorized firmware modification. The results guide the security architecture of the system.
3. Security Architecture Definition
Based on the threat model we define the device security architecture. This includes the device identity model, provisioning strategy, authentication mechanisms, secure firmware update model, and communication security. These decisions establish the trust model of the system and guide implementation.
4. System Specification
Once the architecture is defined, we develop a detailed technical specification describing system architecture, functionality, command structures, communication protocols, and security mechanisms.
- Specification Review
The specification is reviewed together with the client. In practice specifications evolve during development, but this document provides the baseline architecture.
- Project Estimation
Based on the approved specification we estimate the project timeline and budget. Development begins after agreement with the client.
