Tutorial: acra

Not graded — Acra is a database encryption/SQL proxy suite with poison-record IDS, not a standalone protocol honeypot listener. No UHBS protocol grade applies.

What you get from this lab

This tutorial reproduces the published UHBS evaluation proof for analysts who need to verify numbers, not trust a screenshot. After a successful run you should have:

  • SCORECARD.txt — verbatim module table, UHQS, letter grade, and δ_C Safety Gate
  • report.json — machine-readable scores for automation / diffing
  • Optional harness logs under the lab telemetry directory

How CTI / blue team should use the artifacts

  1. Open the full SCORECARD first (authoritative). Treat quick as a smoke check unless the methodology says otherwise.
  2. Read modules A–F with READING-UHQS.md: low B is often “credential sink by design,” not a broken decoy.
  3. Confirm δ_C = 1.0 (or understand why containment failed) before citing UHQS externally.
  4. Wire your own log shipping; UHBS Module C is harness visibility, not SIEM coverage.

Trust limits

  • UHBS 4.2.2 evaluation proof is informative — not a certification, endorsement, or ranking.
  • Product names appear only under docs/conformance/ as evaluation evidence.
  • Re-run after upstream or TPS changes; do not invent scores without regenerating artifacts.
