A remote access tool is software that lets someone connect to and access a computer, server, or network from another location. Depending on the tool and its setup, that may mean helping a person troubleshoot a PC, using another computer’s desktop, administering systems, or monitoring devices.
What does “remote access tool” mean?
The term describes a broad category of software, not one specific feature or product. A joint guide from CISA, NSA, FBI, MS-ISAC, and INCD defines remote access software as enabling a user to connect to and access a computer, server, or network remotely. The guide groups it with related remote administration and remote monitoring and management (RMM) solutions.

In organizational security, “remote access” can have a more specific meaning: NIST defines it as access to an organizational information system by a user or system communicating through an external network, such as the internet. NIST’s glossary notes that readers should consult the source documents it cites for context.

- Remote assistance: A trusted helper connects to a user’s device to diagnose or fix a problem. Microsoft describes Remote Assistance as a way for a helper to take over a PC remotely. Microsoft’s Remote Assistance guidance explains the feature and its use.
- Remote desktop access: A user connects to another computer and interacts with its screen, files, applications, keyboard, and mouse. Microsoft’s Remote Desktop documentation describes these capabilities. Its RDP-file security guidance also explains what a connection request might share.
- Remote administration: An administrator accesses a network or application and performs management tasks on systems at a distance.
- Remote monitoring and management: An RMM agent can report endpoint health and status and may also support administration. Monitoring and control are related functions, but they are not identical.
Remote access software is used in IT, operational technology, and industrial control environments. Administrative tasks can include troubleshooting, gathering device-health data, automating maintenance, configuring computers, recovering or backing up systems, and managing patches. Not every tool provides all of these functions.
How is a remote access tool different from remote assistance?
Remote assistance is one use of remote access: a helper connects to another person’s device to provide support. Remote access is the wider category, which also includes connecting to a desktop for everyday work, administering systems, or monitoring endpoints. The practical distinctions are who initiates and approves a session, what level of control it grants, which devices or resources it can reach, and whether the tool is used only for a session or continuously.

What are the security risks?
Remote access can be legitimate and useful, but it is powerful because a distant user may gain visibility or control over a device or a larger environment. The same capabilities can be abused by attackers to maintain access, move between systems, or remove data, according to the joint government guide. Risk depends on who is authorized, what the session can reach, how access is controlled, and whether activity is monitored; the software category itself is not inherently malicious.

Before opening an RDP file, review the resources it requests: a connection can ask to access local items such as the clipboard, drives, or camera. Microsoft says its Remote Desktop Connection app began displaying new RDP-file security warnings with the April 2026 security update.
