| Verify the audit logs are owned by the "root" group. First determine if a group other than "root" has been assigned to the audit logs with the following command: $ grep log_group /etc/audit/auditd.conf log_group = root Then determine where the audit logs are stored with the following command: $ grep -w log_file /etc/audit/auditd.conf log_file = /var/log/audit/audit.log Then using the location of the audit log file, determine if the audit log is owned by the "root" group using the following command: $ stat -c "%G" /var/log/audit/audit.log root If the audit log is not owned by the "root" group, or log_group is not set to "root", this is a finding. |
| Fix Text (F-73470r1048991_fix) |
| Change the audit logs to be owned by the root group: $ chgrp root /var/log/audit/audit.log Then set the group to root in /etc/audit/auditd.conf by adding or updating the following line: log_group = root |
