+<p> Institutional departments, such as the Biomedical Informatics (BMI) Department of Emory University School of Medicine, manage vast amounts of data, often reaching petabyte scales across multiple Linux-based storage servers. Researchers storing data in these systems need a streamlined way to modify ACLs to grant or revoke access for collaborators. Currently, the IT team at BMI is responsible for manually handling these ACL modifications, which is time-consuming, error-prone, and inefficient, especially as data volume and user demands grow. To address this challenge at BMI and similar institutions worldwide, a Web Management Interface is needed to allow users to modify ACLs securely. This solution would eliminate the burden on IT teams by enabling on-demand permission management while ensuring security and reliability. The proposed system will feature a robust and highly configurable backend, high-speed databases, orchestration daemons for file storage servers, and an intuitive frontend. The proposal includes an in-depth analysis of required components, high-level and low-level design considerations, technology selection, and the demonstration of a functional prototype as proof of concept. The goal is to deliver a production-ready, secure, scalable, and reliable system for managing ACLs across multiple servers hosting filesystems such as NFS, BeeGFS, and others. This solution will streamline access control management and prepare it for deployment at BMI and other institutions worldwide, significantly reducing the manual workload for IT teams. </p>
