In my previous post, Configuring the Azure SQL Database Firewall, I discussed how you can configure the firewall rules to manage access to the SQL Server. Today, I wanted to demonstrate how you can accomplish the same thing with your on-premise SQL Servers by creating a whitelist. So let’s start off by defining “whitelist”. According to the American Heritage Dictionary, it is “a list of people or organizations that have been approved to receive special considerations”.
