Authorization Graph

An Authorization Graph is a visual representation that maps relationships between users, resources, and permissions within a system.

This graph-based model displays how access rights are distributed across an organization's digital infrastructure, showing who can access what resources and through which pathways.

In cybersecurity contexts, authorization graphs serve as powerful tools for understanding complex permission structures, particularly in environments with role-based access control (RBAC) or attribute-based access control (ABAC) systems. Each node typically represents an entity—such as a user, group, role, or resource—while edges represent relationships like membership, inheritance, or direct permissions.

Security teams use authorization graphs to identify potential privilege escalation paths, detect over-privileged accounts, and visualize attack vectors that malicious actors might exploit to gain unauthorized access. By analyzing these graphs, organizations can spot anomalous permission patterns, redundant access rights, and violations of the principle of least privilege.

Modern identity governance platforms often incorporate authorization graph analysis to provide automated risk assessments and recommendations for access cleanup. This visual approach makes it easier to understand and manage complex enterprise environments where traditional tabular permission reports would be overwhelming or difficult to interpret.
