Audit the Tier Zero asset group — list members, validate that every inclusion is intentional, identify drift since the last audit, and certify or revoke certifications as needed. Use when the caller asks "audit Tier Zero", "review the tier list", "who's in Tier Zero and why", or after Tier Zero membership changes are reported in the audit log.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Tier Zero audit Tier Zero is BHE's most consequential asset group — it defines which principals the analysis engine treats as "high value" when computing attack paths. Drift in Tier Zero (a forgotten service account, a stale OU, a misclassified group) compounds: every transitive attack path against the new member becomes a finding. Auditing Tier Zero on a regular cadence is the highest-leverage hygiene activity in BHE. ## Preconditions `bhe-bootstrap` has run and a Tier Zero tag exists. ## Workflow ### 1. Locate the Tier Zero tag `list_asset_group_tags` returns every tag. Find the one named "Tier Zero" (or whatever the deployment called it — but the canonical type is `Tier`). Record its id; every subsequent call references it. If no Tier Zero tag exists, the deployment is malformed — surface that to the caller. Don't try to create one yourself; tag schemas vary across BHE versions. ### 2. Enumerate members + counts Call `count_tag_members(tag_id)` for the cheap rollup (User: 12, Computer: 4, Group: 7). Compare to the operator's expected baseline — sudden growth indicates new inclusions worth investigating. …

How to install
mdr add dreadnode/capabilities/tier-zero-audit@sha256:2ee3a62c7aa7e6f2The line at the top of this page pins the label git:20260504.2a64374, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
