Ubuntu STIG / CMMC Linux Preflight

A signed, versioned Linux collector bundle that produces a locally reviewable evidence package without changing the host.

Public release · version 1.0.0

Ubuntu STIG and CMMC Linux preflight bundle page with local review and secure upload actions.
Public surface captured 2026-09-05.

Context

Linux teams need to see which host evidence is available before mapping remediation or assessment work.

Constraint

Host configuration may be sensitive, so collection, inspection, upload, and review must remain separate operator decisions.

Work

TacitSoft published the collector source, installer, dry-run path, bundle specification, SBOM, checksums, detached signature, provenance record, and public key.

Architecture

  • Versioned shell collector with a no-remediation execution policy
  • Declared bundle schema, manifest, checksums, and sensitivity metadata
  • SBOM, release provenance, detached checksum signature, and public key
  • Canonical source synchronized with the downloadable release

Verified current state

Version 1.0.0 is publicly downloadable with checksum and signature verification, a dry-run path, and automated source-to-release parity tests.

Evidence strength
Signed public release
Evidence basis
Canonical versioned source, published archive, SHA-256 manifest, detached signature, SBOM, provenance record, and release-parity tests.

Operating responsibility

TacitSoft publishes and tests the collector release. The operator runs it locally, reviews every generated file, and initiates any later upload separately.

What remains private

No collected host data is included. Generated bundles may contain sensitive configuration and remain local until an operator reviews them.
