Assessment Title

Rule Text

The audit system must alert the SA when the audit storage volume approaches its capacity.

Description

Discussion Text

An accurate and current audit trail is essential for maintaining a record of system activity. If the system fails, the SA must be notified and must take prompt action to correct the problem. Minimally, the system must log this event and the SA will receive this notification during the daily system log review. If feasible, active alerting (such as e-mail or paging) should be employed consistent with the site’s established operations management systems and procedures.

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

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.hpux11:def:154

if [ ! -f "/etc/rc.config.d/auditing" ]; then echo "PASS"; exit 0; fi

content=$(cat "/etc/rc.config.d/auditing")

if echo "$content" | grep -q "^[ \t]*AUDOMON_ARGS=['\"][^\r\n]*-w[ \t]*([0-9]+)[^\r\n]*[\"']"; then
  warning_level=$(echo "$content" | grep -oP "^[ \t]*AUDOMON_ARGS=['\"][^\r\n]*-w[ \t]*([0-9]+)[^\r\n]*[\"']" | sed's/[^0-9]*//g')
  if [ "$warning_level" -le 90 ]; then echo "PASS"; exit 0; fi
fi

echo "FAIL"; exit 1

Remediation

Edit the AUDOMON_ARGS parameter of the /etc/rc.config.d/auditing file to include -w 90.
