The SLES for vRealize must protect audit information from unauthorized modification.


Finding ID Version Rule ID IA Controls Severity
V-89497 VRAU-SL-000160 SV-100147r1_rule Medium
If audit information were to become compromised, then forensic analysis and discovery of the true source of potentially malicious system activity is impossible to achieve. To ensure the veracity of audit information, the operating system must protect audit information from unauthorized modification. Audit information includes all information (e.g., audit records, audit settings, audit reports) needed to successfully audit information system activity.

Check Text ( C-89189r1_chk )
Verify that the system audit logs with the following command:

# (audit_log_file=$(grep "^log_file" /etc/audit/auditd.conf|sed s/^[^\/]*//) && if [ -f "${audit_log_file}" ] ; then printf "Log(s) found in "${audit_log_file%/*}":\n"; ls -l ${audit_log_file%/*}; else printf "audit log file(s) not found\n"; fi)

If any audit log file has a mode more permissive than "0640", this is a finding.
Fix Text (F-96239r1_fix)
Change the mode of the audit log file(s):

# chmod 0640
