Apache conf files and security

Hi Use OS 6.10.4 on a Readynas Pro2. Using the NAS for websites, installed Mysql, PHPAdmin, and PHP 7.4. The OS installed the Apache server

I see in my Apache Error log that there are many visitors from China, USA, etc that are trying to install harmfull software.

I use the standard apache2.conf that OS 6.10.4 installed

I am using this in my private conf file for my sites, here is an example:

DocumentRoot /xx/xx/xx/xx

ServerName xxxx.yyyy.com

ErrorLog ${APACHE_LOG_DIR}/error.log

CustomLog ${APACHE_LOG_DIR}/access.log combined

   <Directory "/xx/xx/xx/xx/">

      IndexOptions +FancyIndexing NameWidth=*

        Options Includes FollowSymLinks Indexes ExecCGI

        AllowOverride

        All Require all granted

   </Directory>
</VirtualHost>

Is there something I can put in the apache2.conf file for security?

In my Virtual host file, is there something I should correct, delete or change?

Regards Paal
