Access matrix & least privilege

Door Access-Level Planner

Decide who can open which doors before you touch the controller. Toggle each role's access to each door group, and the planner counts your access rules and flags least-privilege problems — a visitor who can reach a restricted room, a vendor with the run of the building. Every person should get the least access their job needs, and no more. Planning aid; runs in your browser.

Least-privilege flags
No least-privilege red flags — every non-admin role is scoped, and Restricted is held only by admin and the security guard. Still confirm against real duties.
The least-privilege principle

Grant each role only the doors its duties actually require, then review it periodically. Fewer open cells means a smaller blast radius if a card or PIN is lost or shared.

Planning aid only — map these roles and zones to your controller's actual access groups and time schedules. Egress and fire-release are separate life-safety settings (see the Emergency-Egress checker) and must never be locked against escape. Verify the final configuration with your integrator.
