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.

# Reconstructed from oval:mil.disa.stig.rhel7:def:118
# The Red Hat Enterprise Linux operating system must be configured so that the SSH private host key files have mode 0640 or less permissive.
# 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): no extractor for field "gexec"
# package openssh-server is removed
# rpminfo_object (rpminfo_test)

fi Assessment Script Powered by AISandbox-executed
A standalone Shell script to assess this control automatically. Review before running it in your environment.
Syntax-checked and actually executed in an isolated sandbox (not the real system this checks) — confirmed to run without errors.
