Configure Amazon Linux 2023 so that the audit logs have a mode of "0600".
Replace "[audit_log_file]" to the correct audit log path, by default this location is "/var/log/audit/audit.log".
$ sudo chmod 0600 /var/log/audit/[audit_log_file]
Check the group that owns the system audit logs:
$ sudo grep -iw log_group /etc/audit/auditd.conf
If the log_group is not defined or it is set to root, configure the permissions as follows:
$ sudo chmod 0640 $log_file
$ sudo chmod 0440 $log_file.*
Otherwise, configure the permissions as follows:
$ sudo chmod 0600 $log_file
$ sudo chmod 0400 $log_file.*
Verify Amazon Linux 2023 audit logs have a mode of "0600".
First 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
Then using the location of the audit log file, determine if the audit log files as a mode of "0640" with the following command:
$ sudo find /var/log/audit/ -type f -exec stat -c '%a %n' {} \;
600 /var/log/audit/audit.log
If the audit logs have a mode more permissive than "0600", this is a finding.
