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.

if [ ! -d "/var/spool/cron/crontabs" ]; then echo "PASS"; exit 0; fi; for file in /var/spool/cron/crontabs/*; do [ ! -f "$file" ] && continue; [ $(stat -c "%a" "$file") -gt 600 ] && { echo "FAIL"; exit 1; }; done; echo "PASS"; exit 0

Remediation

Change the mode of the crontab files.
# chmod 0600 /var/spool/cron/crontabs/*
