3. Securing your Zabbix Server

1. Change default Admin password from Web GUI.

2. There is a default guest access on Zabbix, I prefer to disable it from Web GUI.

Administration > User Groups > No access to the frontend > Add guest account here.

 3. Hide Apache Server Signature and PHP version

nano /etc/apache2/conf-available/security.conf

ServerTokens Prod

ServerSignature Off

nano /etc/php/7.2/apache2/php.ini

expose_php = Off
