SV-226612r603265: Access to the cron utility must be controlled using the cron.allow and/or cron.deny file(s). | Solaris 10 SPARC STIG SCAP Benchmark

Assessment Title

Rule Text

Access to the cron utility must be controlled using the cron.allow and/or cron.deny file(s).

Description

Discussion Text

The cron facility allows users to execute recurring jobs on a regular and unattended basis. The cron.allow file designates accounts allowed to enter and execute jobs using the cron facility. If neither cron.allow nor cron.deny exists, then any account may use the cron facility. This may open the facility up for abuse by system intruders and malicious users.

How this relates to the STIG checklist: STIG vs SCAP benchmark.

Checks

DISA STIG (Manual Reference)

Check for the existence of the cron.allow and cron.deny files.
# ls -lL /etc/cron.d/cron.allow
# ls -lL /etc/cron.d/cron.deny
If neither file exists, this is a finding.

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.

#!/bin/sh
# OVAL Definition: oval:mil.disa.fso.solaris11:def:173
if [ -e /etc/cron.d/cron.allow ] || [ -e /etc/cron.d/cron.deny ]; then echo "PASS"; else echo "FAIL"; fi; exit 0

Remediation

Create /etc/cron.d/cron.allow and/or /etc/cron.d/cron.deny with appropriate content.
