TMA-SOLARIS-4.3

Enable Auditing of File Metadata Modification Events

MediumLevel 1Automatedsolaris

Description

The Solaris Audit service can be configured to record file metadata modification events for every process running on the system. This will allow the auditing service to determine when file ownership, permissions and related information is changed. This recommendation will provide an audit trail that contains information related to changes of file metadata. The Solaris Audit service is used to provide a more centralized and complete window into activities such as these. Audit: each listed event must carry the cis class in /etc/security/audit_event.

How it is checked

Audit method: Shell command

shell
[ -r /etc/security/audit_event ] || exit 1; r=compliant; for e in AUE_CHMOD AUE_CHOWN AUE_FCHOWN AUE_FCHMOD AUE_LCHOWN AUE_ACLSET AUE_FACLSET; do awk -F: -v e="$e" '$2==e && $4 ~ /(^|,)cis(,|$)/ {f=1} END {exit !f}' /etc/security/audit_event || r="$e not assigned to the cis class"; done; echo "$r"
Expected output
compliant

How it is fixed

Fix method: Guidance or infrastructure patch

To enforce this setting, run the following commands to modify the /etc/security/audit_event file and add the cis audit class to the following audit events: # awk 'BEGIN{FS=":"; OFS=":"} {if ($2 ~ /AUE_CHMOD|AUE_CHOWN|AUE_FCHOWN|AUE_FCHMOD|AUE_LCHOWN|AUE_ACLSET|AUE_FACLSET/ ) $4=$4",cis";} {print} ' /etc/security/audit_event > /etc/security/audit_event.CIS # cp /etc/security/audit_event.CIS /etc/security/audit_event
