The data transmitted is sectioned, directed to a channel, encrypted, wrapped, framed and packaged before going over the wire to the other party, then it goes through the same process in reverse. Sending and receiving data through the RDP stack is essentially the same as the 7 layer OSI model for communication.

It allows RDP to communicate through and manage multiple channels. T.125 MCS is a Multipoint Communication Service. RDP uses it in the initial connection request and response. X.224 is a Connection-Oriented Transport Protocol, it provides a connection-mode transport service.

TPKT enables peers to exchange information units that are known as Transport Protocol Data Units ( TPDU or PDU).

TPKT is known as the ISO Transport Service on top of TCP. RDP communication is encrypted with RSA’s RC4 block cipher by default.īefore we get into how an RDP connection actually works, let’s examine the protocols/standards on which RDP relies. The communication during an RDP connection will be extremely asymmetric, while most of the data will go from the server to the client. The basic functionality of RDP is to transmit a monitor (output device) from the remote server to the client and the keyboard and/or mouse (input devices) from the client to the remote server.

“The Microsoft Remote Desktop Protocol (RDP) provides remote display and input capabilities over network connections for Windows-based applications running on a server.” (MSDN)Įssentially, RDP allows users to control their remote Windows machine as if they were working on it locally (well, almost).Ĭommunication in RDP is based on multiple channels, and the protocol theoretically supports up to 64,000 unique channels. Our hope is that you’ll walk away with a basic understanding of the protocol so you can continue reading and researching further about the protocol for any future needs. Since we weren’t able to find a digestible overview of this protocol, in this article we’ll walk through the basics of RDP, how they work, and how some of the critical vulnerabilities found in RDP fit into the bigger picture of an actual RDP connection. RDP is relevant now more than ever, having Microsoft’s Azure and Hyper-V platforms using it as the default remote connection protocol and having the interest in this protocol by attackers rise, both as an initial infection vector and as a propagation method. This is why the security industry needs to educate itself about it. RDP is a complex protocol with many extensions and the potential of finding new critical bugs is still high. It is now essential knowledge that is absolutely crucial for everyone in the security industry. The importance of knowing and understanding RDP has never been greater – especially in light of the recent critical vulnerabilities that were found in the protocol.

In fact, there are more than 4.5 million RDP servers exposed to the internet alone, and many more that are accessible from within internal networks. RDP is an extremely popular protocol for remote access to Windows machines. RDP Security | Recent RDP Vulnerabilities.Connection Sequence | Basic Input and Output.
