Assessment Title

Rule Text

The /etc/zones directory, and its contents, must not be group- or world-writable.

Description

Discussion Text

Solaris zones configuration files must be protected against illicit creation, modification, and deletion.

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

Checks

DISA STIG (Manual Reference)

Check the permissions of the files and directories.

# ls -lLdR /etc/zones

If the mode of a directory is more permissive than 0755, or the mode of a file more permissive than 0644, this is a finding.

If zones are not installed on the system, this is not a finding.

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.

#!/bin/bash
# Reconstructed from oval:mil.disa.fso.solaris11:def:22
# The /etc/zones directory, and its contents, must not be group- or world-writable.
# 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) -- /etc/zones contents must have permission 0644: no extractor for field "gexec"

# directory must have permissions 0755 
# file_object (file_test)
test_1() {
  ( (stat -c '%A' '/etc/zones' | awk '{print (substr($0,9,1)=="w")?"true":"false"}') | grep -qxF 'false' ) && ( (stat -c '%A' '/etc/zones' | awk '{print (substr($0,6,1)=="w")?"true":"false"}') | grep -qxF 'false' )
}

if ! test_1; then
  echo "PASS (automated portion only -- MANUAL REVIEW still required, see notes above)"
else
  echo "FAIL (or see MANUAL REVIEW note above)"
fi

Remediation

Change the mode of the file or directory.

# chmod 0644 <file>
For directories:
# chmod 0755 <directory>
