vrp-ir 0.9.0: a line-cited security audit for Huawei VRP/USG configs

#python #opensource #networking #security

If you do acceptance or audit work on Huawei gear, you've hit this wall:

  • Batfish explicitly marks Huawei VRP as unsupported.
  • ntc-templates parses display show-commands, not config files.
  • So you're back to grep + screenshots over display current-configuration.

vrp-ir fills exactly that gap, and 0.9.0 is out.

What it does

It parses an offline Huawei VRP/USG config into a typed model where every value carries a SourceRef back to its exact file:line — then turns that into a security acceptance audit where every finding cites the line it's based on.

pip install vrp-ir

vrp-ir audit firewall.cfg            # Markdown report, every finding line-cited

vrp-ir audit firewall.cfg --strict   # exit 1 on FAIL -> drop it in CI
Enter fullscreen mode Exit fullscreen mode




New in 0.9.0

  • SARIF + JUnit output — pipe the audit into GitHub/GitLab code scanning or a CI gate. A permit-any rule or cleartext Telnet now fails the build with the line.
  • SNMPv3 checks (+ 16 others: cleartext mgmt, weak SSH ciphers, missing NTP, default-deny, permit-scope, address-set-resolves-to-any…). 17 checks total.
  • GB18030 / Chinese configs parse cleanly — real-world configs, not just ASCII.
  • Evidence policy — "no source, no claim": a finding never asserts PASS/FAIL without a cited line; coverage gaps are surfaced, not hidden.
  • Advisory standards mapping to common control domains (incl. China's MLPS Level 3/4) — advisory, not a certification.

Zero runtime dependencies. Apache-2.0.

Why provenance matters

An audit tool's worst failure is a wrong finding that looks authoritative. So vrp-ir's rule is the opposite of most linters: if it can't trace a fact to a source line, it says so (UNCHECKED) rather than bluffing a pass.

It's the open core of AegisTwin (acceptance at scale). The single most useful contribution is a real, de-identified config we parse wrong — that's the best possible issue.
