Reference Implementation — Enterprise Access Graph

Reference Implementation — Enterprise Access Graph

Role and policy traversal for effective access computation, entitlement review, and zero-trust auditing.

Why it matters

Access logic spread across services is hard to audit. A graph makes effective permission paths inspectable in one place.

Going deeper

Implementation shape:

• Authoritative graph for identities, teams, roles, and grants.
• Real-time effective access query endpoint with bookmark-based consistency.
• Quarterly certification workflows over path evidence.
• Drift monitors for orphaned roles and stale grants.

An access graph is turning a tangle of door keys into a visible floor plan. When permissions are JSON blobs scattered across services, 'who can actually open this room?' is a forensic exercise. As traversable grant paths, the effective permission is one query you can show an auditor.

• Permissions as JSON blobs on users. Un-auditable, un-traversable. Fix: model user→team→role→resource as typed edges.
• No effective-access endpoint. Every audit is bespoke. Fix: one query computes effective permission with path evidence.
• No drift monitor. Orphaned roles/stale grants accumulate. Fix: scheduled certification over path evidence.
