fwintegrity 0.4.1

Firewall rule and config integrity checks across exports and change systems

fwintegrity

Compare policy audit exports (tabular) with change tickets (CSV or dict rows). Normalize addresses, services, and change kinds, then match rows bidirectionally or build atomic triple indexes for coverage checks.

Install

pip install fwintegrity

Quick use

from fwintegrity import (
    AUDIT_EXPORT_DEFAULT_MAPPING,
    TICKET_CSV_DEFAULT_MAPPING,
    build_ticket_triple_index,
    from_csv_text,
    link_audit_to_ticket_requests,
    load_change_rows,
)

audit_rows = load_change_rows(from_csv_text(audit_csv), AUDIT_EXPORT_DEFAULT_MAPPING)
ticket_rows = load_change_rows(from_csv_text(ticket_csv), TICKET_CSV_DEFAULT_MAPPING)
links = link_audit_to_ticket_requests(audit_rows, ticket_rows)
idx = build_ticket_triple_index(ticket_rows)

Legacy string audit CSV (wide _CANON headers) still works: link_audit_to_ticket_requests(audit_csv_text, ticket_csv_text).

See scripts/sample_demo.py for a minimal example.

Documentation

• Customization guide — how to adapt parsers, column maps, ignore lists, and matching rules to your organization’s formats (vendor-neutral extension points).

Features (summary)

• Endpoints: IPv4 literals/CIDR, prefixed audit-export tokens (IP_, Host_, net_, Range_, …), optional object/group names; mixed cells become AddrCompound.
• Services: TCP_443-style audit tokens, loose ticket strings (TCP 80 UDP 53), optional service object names → ServiceCompound.
• Matching: bidirectional containment on source, destination, and service (change_match, compare_changes).
• Triples: TicketTripleIndex / audit_triples_all_in_index for (src_atom, dst_atom, svc_atom) style checks.
• Loading: declare columns with ChangeRowMapping, then from_csv_text / from_csv_path / from_excel_path / from_dict_rows / from_package_resource + load_change_rows (see table_load.py).

Requirements

Python 3.10+

Development

pip install -e ".[dev]"
pytest
ruff check src tests

Build and publish to PyPI

1. Create a PyPI account and API token.
2. Bump version in pyproject.toml and src/fwintegrity/__init__.py (__version__).
3. Build and upload:

pip install build twine
python -m build
twine check dist/*
twine upload dist/*

Use TestPyPI first if you prefer: twine upload --repository testpypi dist/*

Customization (PyPI / offline)

The wheel ships the Python package only. Vendor-specific behavior is adjusted by editing or wrapping:

Area	Location
Column mapping + unified load	table_load.ChangeRowMapping, load_change_rows, from_* sources; optional mapping= on load_audit_table / load_ticket_table
Audit CSV header → keys (legacy wide export)	audit_report._CANON
Ticket id columns	ticket._TICKET_NUMBER_KEYS
Address & service parsing	normalize.parse_*, expand_audit_network_token, _iter_loose_tcp_udp_segments
Change-kind compatibility (audit vs ticket)	compare.DEFAULT_AUDIT_TO_TICKET_KINDS or pass matrix=
Ignored services (ICMP, etc.)	ignore_lists.DEFAULT_IGNORED_SERVICE_NAMES, merged_ignored_service_names
Triple key strings	triple_index.endpoint_atom_keys, service_atom_keys
