If you need certificates for your internal websites, applications, wireless network or pilot lab test, having an internal enterprise authority server is a good choice. Today, I am going to show you how to deploy an Enterprise Authority root server on Microsoft Windows server 2019. This is the simple way to have a certificate service for Internal and easy to maintain but it maybe not a good best practice, if you need the certificate service is deployed securely, you need to consider deploying Two-Tier (or more) PKI Hierarchy (at least a Root CA server and a subordinate server), I will show you how to deploy them for future post.
