Which agreement dictates the security controls for data exchange between partners?

The agreement that specifically outlines the security controls for data exchange between partners is the Interconnection Security Agreement (ISA). This document serves a crucial role in establishing the security requirements and protocols necessary for the secure transfer of data between interconnected systems. It details various aspects including physical security measures, and configuration settings, and specifies roles and responsibilities related to data protection, ensuring both parties comply with applicable regulations and standards.

In contrast, while the Business Partnership Agreement (BPA) focuses on the overall partnership terms and might include general provisions regarding data sharing, it does not specifically address the technical and procedural security controls for data exchanges. The Third-Party Connection Agreement (TCA) is not a common term in cybersecurity frameworks; rather, it's often confused with ISAs. The Master Service Agreement (MSA) defines the working relationship between service providers and their clients but typically doesn’t delve into the specific security controls necessary for the secure exchange of data. Therefore, the ISA emerges as the most precise agreement in this context, providing a comprehensive framework for ensuring secure data interchange.
