Why is it important to authenticate your server?
One critical thing is to make sure that your servers can be authenticated by the client in order to prevent MiTM (Man in the Middle) attacks. When the client is domain-joined and on the same network as the server Kerberos can usually be used. Depending on your needs you may want to purchase certificates (or perhaps single wildcard) from a trusted public provider and assign to the RDP-Tcp listener on each server.
What port does RDP use?
By default, RDP uses TCP port 3389 and UDP port 3389. RDP is designed to support different types of network topologies and multiple LAN protocols. On the target server, RDP uses its own video driver to render display output into network packets and then uses the RDP network protocol to send them to the Remote Desktop client. The RDP client receives rendered display data and converts it into Microsoft Windows graphics device interface (GDI) API calls that are displayed by the Remote Desktop client.
Why is RDP important?
RDP is an important security vector and if hackers find a way into RDP they can validate user accounts, expose passwords, and infect your internal systems with malware and ransomware. By default, the highest available encryption supported by both the client and server is used for RDP connections.
Why is remote desktop important?
Remote Desktop enables the SMB administrators to diagnose and resolve problems remotely. However, Remote Desktop is a powerful tool that often uses highly privileged access to the remote systems in your network. As such security for Remote Desktop is critically important. The failure to implement the proper security precautions can open the door to both malware and ransomware attacks and that Remote Desktop exploits can be difficult to spot because they have no user input.
What is RDP server?
The RDP server uses its own keyboard and mouse driver to process these events. In addition, RDP has the ability to redirect other local client resources to the remote RDP target including the clipboard, printers, and local drives.
What is remote desktop?
Remote Desktop is the SMB (Server Message Block) administrator’s go-to remote administration tool.

Does 2008R2 use encryption?
I can see that the 2008R2 are set to use high encryption from the remote desktop configuration gui, so I assume the policy has applied to the 2012R2 servers as well.
What is the high encryption level?
High: The High setting encrypts data sent from the client to the server and from the server to the client by using strong 128-bit encryption. Use this encryption level in environments that contain only 128-bit clients (for example, clients that run Remote Desktop Connection). Clients that do not support this encryption level cannot connect to RD Session Host servers.
What is a RDP policy setting?
This policy setting specifies whether to require the use of a specific security layer to secure communications between clients and RD Session Host servers during Remote Desktop Protocol (RDP) connections.
What is RDP in computer?
Windows Remote Desktop Protocol (RDP) is widely used by system administrators trying to provide remote operators access. In a shocking oversight this connection does not use strong encryption by default. This post will walk through the steps required to force TLS encryption on all RDP connections.
What is SSL 1.0?
SSL (TLS 1.0): The SSL method requires the use of TL S 1.0 to authenticate the RD Session Host server. If TLS is not supported, the connection fails. This is the recommended setting for this policy.

What is remote access security?
Remote access security begins with hardening the devices seeking to connect, as demonstrated in Chapter 6. We follow this with a selection of one or more remote access methods based on functional and technical requirements. Finally, we control access based on context.
What is remote access?
Remote access is no longer just about a laptop or home desktop user connecting to catch up on some work or update customer and order information. The explosion of consumer devices in the hands of our employees changes how we look at remote connectivity. In addition to supporting various platforms and proprietary operating systems, traditional security controls do not provide sufficient granularity for policy enforcement. This results in either lax security or inflexibility in how we deliver business services.
Why do organizations use VPNs?
Organizations use VPNs for all WAN, B2B, and remote user requirements, rapidly replacing frame relay and point-to-point T-carrier implementations. In addition, modems have not been used in most businesses in years as Web portals powered by encryption technology replaced modem pools. VPN provides many capabilities not available in simple HTTPS connections, causing a shift to VPN for company intranet connectivity.
How many T1s can be bonded?
When an organization requires more bandwidth, it can bond multiple T1s to look like a single connection. For example, bonding two T1s results in bandwidth of about 3 Mbps. Another option is to implement a full or partial T3 circuit. A T3 is an aggregate of 28 T1s, providing bandwidth of 44.736 Mbps.
How is context based access control facilitated?
Context-based access control is facilitated by first defining policies, as depicted in Figure 9-9. Remote access policy must address who, what, when, where, and with what is access allowed and to what extent. Figure 9-10 depicts an example of how an organization might apply a set of polices.
What is expanding connectivity requirements?
The expanding connectivity requirements are exceeding the ability of our traditional access and admission control technologies. For example, is the acceptable use policy the same for remote employee-owned tablets as it is for company-owned laptops? Should it be? How can we enforce different policies for different devices?
Which is better: ESP or IPSEC?
If an organization requires confidentiality over IPSec, ESP is the better choice. ESP is configurable in tunnel or transport mode. Transport mode provides data payload encryption for each packet, but it does not ensure authentication and integrity of packet content. Tunnel mode, however, results in encapsulation of the entire packet. The original packet header is hidden and a new header added. For remote access, ESP in tunnel mode is the preferred configuration.
