Fix Recommendation

Configure the audit log directory and its underlying files to be owned by "root" group.

Set the "log_group" parameter of the audit configuration file to the "root" value so when a new log file is created, its group owner is properly set:

$ sudo sed -i '/^log_group/D' /etc/audit/auditd.conf
$ sudo sed -i /^log_file/a'log_group = root' /etc/audit/auditd.conf

Signal the audit daemon to reload the configuration file to update the group owners of existing files:

$ sudo systemctl kill auditd -s SIGHUP

Check Contents

Verify the group owner is set to own newly created audit logs in the audit configuration file with the following command:

$ sudo grep -iw log_group /etc/audit/auditd.conf
log_group = root

If the value of the "log_group" parameter is other than "root", this is a finding.

Determine where the audit logs are stored with the following command:

$ sudo grep -iw log_file /etc/audit/auditd.conf
log_file = /var/log/audit/audit.log

Using the path of the directory containing the audit logs, determine if the audit log files are owned by the "root" group with the following command:

$ sudo stat -c "%n %G" /var/log/audit/*
/var/log/audit/audit.log root

If the audit log files are owned by a group other than "root", this is a finding.
