1. Overview Hardening is the process of securing a system by reducing its surface of vulnerability. We will show you how to reduce available ways of attack this includes enabling FIPS mode, changing the default password, encrypting configuration passwords, limiting SSL Protocols and Ciphersuites, replacing Certificates, setting a bootloader password, disable root access with SSH root, securing the MySQL/MariaDB Databases, setting Firewall rules and resetting RCDevs Virtual Appliance root password… Please consider carefully which of these settings are relevant for your use.

1. How to Use my Own Trusted Certificate in WebADM During installation, WebADM generates its own certificate authority certificate and server SSL certificates. Yet, you can use your own SSL certificates instead of the pre-generated ones. Using a trusted certificate may be required when you use the RCDevs OpenID IDP, and to avoid user browser warnings when accessing the WebApps. Just create the SSL certificate and key files in /opt/webadm/pki/custom.crt and /opt/webadm/pki/custom.
