SCC Automation Reference

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.

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.

for file in $(find / -type f -name "*.mib" 2>/dev/null); do \
  [ $(stat -c "%a $file" 2>/dev/null) != "640 $file" ] && echo "FAIL" && exit 1; \
done
echo "PASS"
exit 0

Remediation

Change the mode of MIB files to 0640.
# chmod 0640 <mib file>
