What is remote desktop protocol (RDP)?Remote desktop protocol (RDP) is a secure network communications protocol developed by Microsoft. It enables network administrators to remotely diagnose problems that individual users encounter and gives users remote access to their physical work desktop computers. Show
RDP can be used by employees working from home or traveling who need access to their work computers. RDP is also often used by support technicians who need to diagnose and repair a user's system remotely and by admins providing system maintenance. To use a remote desktop session, a user or admin must employ RDP client software to connect to the remote Windows PC or server running RDP server software. A graphical user interface enables the remote user or admin to open applications and edit files as if they were sitting in front of their desktop. RDP clients are available for most versions of Windows as well as for macOS, Linux, Unix, Google Android and Apple iOS. An open source version is also available. RDP is an extension of the International Telecommunications Union-Telecommunication (ITU-T) T.128 application sharing protocol. Features of RDPRDP is a secure, interoperable protocol that creates secure connections between clients, servers and virtual machines. RDP works across different Windows OSes and devices and provides strong physical security through remote data storage. Noteworthy properties of RDP include the following:
It is worth noting that not every RDP client supports all of these features. Additionally, a client might only support certain features when operating in enhanced session mode. RDP use casesThere are three main use cases for RDP. These include the following:
How does remote desktop protocol work?RDP provides remote access through a dedicated network channel. An RDP-enabled application or service packages the data to be transmitted, and the Microsoft Communications Service directs the data to an RDP channel. From there, the OS encrypts the RDP data and adds it to a frame so that it can be transmitted. The Terminal Server Device Redirector Driver handles all RDP activity. This kernel driver comprises subcomponents such as the RDP driver, which handles user interfaces, transfers, encryption, compression and framing. The transport driver is responsible for packaging the protocol sent across a TCP/IP network.

What are the issues with RDP?
RDP security concernsIt is important to follow RDP best practices when running RDP -- such as not using open RDP connections over the internet or giving anyone direct access to an RDP server. Other precautions include defense-in-depth, which uses multiple layers of security, and the principle of least privilege, which limits user access to only the systems needed. The BlueKeep security flaw affected users of earlier versions of Windows by installing malicious programming and making changes to data. First discovered in May 2019, these vulnerabilities affected Windows 7, Windows XP, Windows 2000, Windows Server 2003 and Windows Server 2008. Historically, RDP has been susceptible to pass the hash attacks and computer worms. Though less effective, brute force attacks have gained access to past and present versions of RDP. Microsoft provided security patches for those earlier Windows versions, and newer versions of RDP are far more secure. More recent Windows OSes contain a mechanism for specifying which users are allowed to access the system through an RDP session. There is also an option to prevent anyone from remotely accessing the system unless they use network-level authentication. RDP vs. VPNAlthough some people compare RDP and VPN, the two technologies are significantly different. A virtual private network provides a network path to an organization's network resources. A remote user who has a VPN connection could work the same way they would be able to if they were working on premises. Where a VPN provides connectivity to a remote network, RDP provides connectivity to a specific remote resource. This resource is usually a physical or a virtual computer, but some solutions allow RDP connections to specific remote applications. Alternatives to RDPRDP is one of the most widely used remote access protocols, but alternatives exist. For screen-sharing and remote control, one option is Screens from Edovia. Screens can remotely control macOS or iOS systems from anywhere in the world. The company also makes a product called Screens Connect that makes Mac and Windows systems remotely accessible, while the Screens Express utility allows users to grant someone else temporary access to their Mac. Zoho Assist is primarily designed to provide remote support but can also offer unattended remote access. Zoho Assist is a paid product, but the company also provides a lightweight free edition. It's important to keep in mind that not all VDI software supports all display protocols, so choosing a protocol often depends on what VDI software the organization is using. If the goal is to find an alternative to connect users to a remote or virtual desktop, popular options include Citrix HDX, PC over IP and VMware Blast Extreme. Numerous security threats are associated with RDP, including computer worms and ransomware attacks. Learn how ransomware affects organizations and the real-life consequences of these attacks. Which protocol is used to access a Windows desktop interface remotely?Remote desktop protocol (RDP) is a secure network communications protocol developed by Microsoft. It enables network administrators to remotely diagnose problems that individual users encounter and gives users remote access to their physical work desktop computers.
When configuring remote Assistance list the 3 methods in which an invitation may be sent?Using Remote Assistance, an administrator of one server can request or offer remote assistance to an administrator of another server.. Using Windows Messenger. ... . Sending an e-mail. ... . Saving and transferring a file.. What protocol handles a Terminal Services connection to a Windows based PC?The Microsoft Remote Desktop Protocol (RDP) provides remote display and input capabilities over network connections for Windows-based applications running on a server. RDP is designed to support different types of network topologies and multiple LAN protocols.
