Claims a 63% cut in AWS permissions by applying three concrete steps: revoke permissions not accessed in 90 days, drop permissions with a Permission Utilization Ratio under 10%, and split broad admin roles into focused subroles to cut permissions per user. Analysis runs on Python + Colab + SigmaJS + SQLite, computes a role-level Under-Utilization Ratio, and produces graphs. Operationalize with automated weekly policy generation that rebuilds and attaches least-used IAM policies.
