Properly Securing Microsoft’s Remote Desktop Gateway

For decades, Microsoft’s Remote Desktop Protocol (RDP) has been used to connect to Windows computers remotely. We covered in detail many of the reasons that RDP itself presents such a high risk when exposed directly to the internet. Microsoft provided a solution to the numerous RDP-related security woes by releasing a service called Remote Desktop Gateway (RDG).

Remote Desktop Protocol: A Virtual Open Door?

Remote Desktop Protocol (RDP) is arguably the most prolific remote access tool in use today. As its name indicates, RDP defines how server and client components communicate in order to provide a graphical interface from one computer to another “remote” computer. Microsoft includes RDP functionality with most versions of its Windows operating system making it very popular and relatively easy to use.
