![]() ![]() But there may still be other design flaws that could leave the environment vulnerable to an attack. Installing a web application firewall (WAF) and restricting traffic here could be good first steps towards controlling input. Without visibility into what can go wrong in this scenario, you may overlook signs of malicious activity. As illustrated in the following diagram, integrating a third-party service with an organization’s legacy system can introduce blind spots in data flows: In these (quite common) scenarios, critical data flows between system components-as well as their primary entry points, such as open ports-can become obfuscated. Threat modeling sessions can become even more complex when integrating modern services with legacy systems. ![]() On top of that, the implementation of a system might not match its initial design, and outdated system models and documentation can muddy the process. But for long-running systems with sprawling, complex infrastructure-where operational knowledge is often limited to a few team members-threat modeling sessions can be impacted by substantial gaps in visibility. In these environments, organizations typically have end-to-end visibility into development and deployment, so they can easily see how each piece of a system fits together. Develop accurate system models with distributed tracingĬreating threat models for small systems or new system components is relatively straightforward. ![]() In this post, we’ll look at how you can use distributed tracing and Datadog ASM for system modeling and threat elicitation to build effective threat models. By leveraging distributed traces through its integration with Datadog APM and real-time network data, ASM provides organizations with an up-to-date view of the composition and state of their systems before, during, and after requests. This critical visibility enables organizations to quickly identify threats in their existing application topology and anticipate the flow of potential attacks. If threat models do not keep up with system changes, organizations will end up with an incomplete picture of their infrastructure’s attack surface.ĭatadog Application Security Management (ASM) addresses these gaps by helping organizations map their entire system, which can surface design flaws in application and business logic that static threat models may miss. This is a cyclic process, because an organization’s threat models must adapt as their systems evolve.
