What methodology focuses on the authorized movement and execution of data within a system?

The methodology that focuses on the authorized movement and execution of data within a system is data-centric threat modeling. This approach emphasizes understanding how data flows through a system, identifying potential threats at each stage, and ensuring that appropriate controls are in place to protect data. By modeling data-centric threats, organizations can proactively identify vulnerabilities that may arise from unauthorized access or data manipulation, making it essential for securing sensitive information.

Data-centric threat modeling differentiates itself by focusing specifically on the data rather than just the applications or infrastructure where the data resides. This perspective allows for a more granular analysis of how data is used, processed, and stored, and helps in aligning security measures with business objectives and compliance requirements.

In contrast, other methodologies mentioned do not focus directly on the management of data movement and execution. For instance, DevOps aims to integrate development and operations to streamline software delivery and does not specifically address data management. Dynamic Application Security Testing (DAST) is a testing approach that evaluates the security of an application during runtime but isn't primarily centered on data flow. Encapsulation refers to an object-oriented programming principle that hides the internal state and behavior of an object but does not address data movement within a system context. Thus, the focus on authorized data handling distinctly aligns data-centric
