Solution
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.*
