A Centralized Authentication and Authorization Framework For Enterprise Security Modernization

Key Points

The initiative modernizes identity and access management across a large digital ecosystem, enhancing security.
A novel token taxonomy includes software/application, people, and device tokens, improving access control mechanisms.
The design incorporates RBAC, ABAC, and ReBAC models for fine-grained, context-aware access control across systems.
Centralized management of API tokens enables low-code integration and uniform enforcement, simplifying processes.

Abstract

This paper presents the design and implementation of Telecom’s enterprise-wide Authentication and Authorization Initiative, aimed at modernizing identity and access management (IAM) across a large-scale digital ecosystem. The initiative introduced a novel token taxonomy - Software/Application Tokens, People Tokens, and Device Tokens - enabling fine-grained, context-aware access control using RBAC, ABAC, and ReBAC models. A Security Library Framework was developed to centralize API token lifecycle management, incorporating low-code integration for developers and uniform enforcement across distributed systems.
