Humans think in terms of resource types, classifications, and the relationships between the resources. In order to answer complex and abstract questions, we must model a system in a similar way to how humans think. Abstracting away details of individual systems allows us to obtain a wider and deeper understanding of our environments that we cannot easily obtain otherwise. In this talk, we will discuss how graphs provide deep insight into systems for security analysis, the complexities around developing uniform models, and open source tooling that JupiterOne has created to maximize visibility and simplify security operations.
