Application Threat Risk Assessment as a Service

ATRAaaS

When conducting an **application threat risk assessment**, it’s essential to identify, assess, and manage potential risks associated with an application. This process not only helps prevent the exposure of security defects and vulnerabilities but also allows you to view your app from the perspective of cybercriminals and attackers.

Here’s a structured approach to application threat modeling that can guide you through the process:

1. **Decompose the Application**:

   – Understand how the application is used by creating use cases.

   – Identify entry points where potential attackers could interact with the application.

   – Identify assets—items or areas that attackers would be interested in.

   – Determine trust levels representing access rights granted to external entities.

   – Document this information in a Threat Model document and use it to create data flow diagrams (DFDs) for the application. DFDs illustrate different paths through the system, highlighting privilege boundaries.

2. **Determine and Rank Threats**:

   – Use a threat categorization methodology (such as STRIDE or the Application Security Frame) to identify threats from both attacker and defensive perspectives.

   – DFDs from step 1 help identify potential threat targets (e.g., data sources, processes, data flows, user interactions).

   – Classify these threats further as roots for threat trees (one tree per threat goal).

   – From a defensive perspective, ASF categorization helps identify threats as weaknesses in security controls.

Remember that threat modeling should be an integral part of your software development life cycle (SDLC) to enhance product security. By systematically addressing security risks early in the development process, you can build more resilient applications.
