Assessment Title

Rule Text

The system syslog service must log informational and more severe SMTP service messages.

Description

Discussion Text

If informational and more severe SMTP service messages are not logged, malicious activity on the system may go unnoticed.

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

Checks

DISA STIG (Manual Reference)

Check the syslog configuration file for mail.crit logging configuration.

Procedure:
# more /etc/syslog.conf

Verify a line similar to one of the following lines is present in syslog.conf is configured so that critical mail log data is logged. (Critical log data may also be captured by a remote log host in accordance with GEN005460.)

mail.crit /var/adm/messages
*.crit /var/log/messages

Less severe syslog levels (err, warning, info, and debug) may be substituted for crit, since they will also capture crit level syslog messages.  If syslog is not configured to log critical Sendmail messages, this is 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.

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
# DISA STIG / SCAP compliance check for syslog service logging SMTP messages - oval:mil.disa.fso.solaris11:def:273
if [ ! -f "/etc/syslog.conf" ]; then echo "PASS"; exit 0; fi
if grep -q "^[^#]*mail\\.crit" /etc/syslog.conf || grep -q "^[^#]*\\*\\.crit" /etc/syslog.conf; then echo "PASS"; exit 0; fi
echo "FAIL"; exit 1

Remediation

Edit the syslog.conf file and add a configuration line specifying an appropriate destination for mail.crit syslogs.
