Why it matters
Google’s IAM Helper separates policy inspection from access changes. Its public workflows retrieve a baseline, simulate proposed allow-policy changes against historical access, and require approval before applying them. PAM supports scoped, time-bound grants. Historical replay cannot prove that future or previously unseen workloads will retain access.
My takeaway: Inspect the IAM skills before adoption and restrict the identity running them. Save the current policy, simulate the proposed allow-policy change, investigate revoked or uncertain access, and require approval before applying it. Test new workloads separately; configure PAM approvers and expiry, then verify that elevated access ends.
