The reconstructed evaluation script behind this rule's OVAL check(s) — every module a compound check combines, with this rule's own concrete values and DISA's SCC tool's real per-module mechanism curated from static teardown of SCC releases.
#!/bin/bash
# Reconstructed from oval:mil.disa.fso.hpux11:def:84
# The /etc/shadow (or equivalent) file must have mode 0400.
# Per-module read mechanism curated from static teardown of DISA's SCC tool
# (SCAP Compliance Checker) -- see the SCC Automation Reference above.

# MANUAL REVIEW REQUIRED -- the module(s) below could not be reconstructed
# into working code from curated SCC reference data, and are excluded from
# the automated result:
# - file_object (file_test) -- /tcb/files/auth/*/* files mode 0664: no extractor for field "sgid"
