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.sles12:def:233
# The SUSE operating system SSH daemon private host key files must 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"
# The openssh package is installed
# rpminfo_object (rpminfo_test)
test_1() {
rpm -q --quiet 'openssh' &>/dev/null
}
# The ssh daemon is running
# process58_object (process58_test)
test_2() {
ps -eo args | grep -P '^/usr/sbin/sshd\b' &>/dev/null
}
if ( test_1 && test_2 ); then
echo "PASS (automated portion only -- MANUAL REVIEW still required, see notes above)"

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.
