Using firewalls is a common way to protect and secure access to IoT devices. Yet, it’s challenging to access and manage devices deployed at remote sites, behind firewalls that block all inbound traffic. This necessitates creative solutions like reverse tunnels or cloud-based connectivity services that initiate outbound connections. As a result, some users cut corners to gain remote access to their IoT devices, but in the process, they’re leaving doors open for lurking cybercriminals to sneak in undetected. This underscores the critical importance of secure setup and adherence to best practices.
Connectivity itself can be a hurdle. Ensuring you have a router, modem, or gateway compatible with your IoT device is step one. For industrial environments, robust networking equipment designed for Industrial IoT (IIoT) is essential. Moreover, reliable internet connectivity is paramount. While traditional broadband works for many home setups, large-scale or remote deployments might require alternative solutions. Cellular connectivity is possibly one of the cheapest and most efficient ways to connect IoT devices over the internet, especially for mobile or geographically dispersed devices. Cellular options are more effective since they offer widespread coverage and dedicated IoT plans. Satellite networks can also be used for extremely remote locations where other options are unavailable.
Setting Up Remote Access for Your IoT Devices
Now that we understand the different remote access methods available, let’s move on to the steps involved in setting up remote access for your IoT devices. Setting up remote access for your IoT devices may vary depending on the specific device and manufacturer. However, here are some general steps to guide you through the process.

Next, you'll need to prepare your remote access server or platform. This could be a dedicated Linux server, a cloud platform account (like AWS IoT), or a service that facilitates remote connections. Ensure your server has a static IP address or a dynamic DNS service configured if it's not cloud-based. You'll also need appropriate login information for your server and, if applicable, for the device manufacturer's cloud platform. Configure your IoT device to connect to the device manufacturer’s cloud platform if that's your chosen remote access route.
Popular Methods for Remote IoT Device Access
There are several established methods for achieving remote connect IoT device functionality, each with its own strengths and ideal use cases. Understanding these options will help you choose the most appropriate solution for your specific needs.
SSH (Secure Shell) Connection
As mentioned, SSH is a cornerstone for secure remote access. It provides a secure channel over an unsecured network by encrypting the traffic between the client and the server. For IoT devices running Linux distributions (like Raspberry Pi), SSH is the go-to for command-line access, file transfers, and secure tunneling. When you use remote connect IoT device SSH Windows, you are leveraging this secure protocol to interact with your devices safely, ensuring data integrity and confidentiality. To learn more, refer to how to set up and configure your IoT for remote SSH access over the internet. This method is particularly useful for developers and administrators who need direct, secure command-line control over their devices.
VNC (Virtual Network Computing)
Connect to IoT remotely over the internet using VNC. Virtual Network Computing (VNC) is a protocol for safely accessing the IoT graphical user interface (GUI) or desktop. It is widely used for remote device management and file transfer, especially when a visual interface is preferred over a command-line interface. For IoT devices that have a desktop environment (e.g., a Raspberry Pi running a desktop OS), VNC allows you to see and interact with the device's screen as if you were sitting in front of it. This is incredibly useful for graphical applications, debugging visual elements, or training purposes.
RDP (Remote Desktop Protocol)
Similar to VNC but primarily associated with Windows environments, RDP allows users to connect to an IoT device's remote desktop using an RDP client. With XRDP (an open-source RDP server) up and running on your IoT device (if it's Linux-based), you can now connect to it using an RDP client such as Remote Desktop Connection (RDC) in Windows or Remmina in Linux. This provides a full graphical desktop experience, making it easy to manage files, run applications, and configure settings visually, much like VNC but often with better performance over varying network conditions for Windows-based systems or XRDP configured Linux systems.
Cloud Platforms (AWS IoT, Arduino Cloud)
Cloud platforms offer a comprehensive solution for remote connect IoT device management, abstracting much of the underlying networking complexity. How do I use AWS IoT SSH for remote device access? AWS IoT devices require a secure setup with appropriate IAM roles and tunneling, allowing for secure remote access without direct inbound connections to the device. These platforms provide a centralized dashboard to monitor, manage, and interact with devices. The Arduino IoT remote phone application, for example, lets you control and monitor all of your dashboards in the Arduino Cloud. With the app, you can also access your phone's internal sensors such as GPS data, light sensor, IMU, and more (depending on what phone you have). This highlights the power of cloud platforms to integrate device control with mobile applications and other services, offering a highly scalable and flexible remote management solution.
When using cloud platforms, you often select the remote server option under IoT server and supply the IP address of the server, plus the login information. You can then use the remote device to verify the presence of the registered IoT devices. These platforms often handle the complexities of firewalls and dynamic IP addresses through secure tunnels and message brokers, simplifying the remote access process for users.
Risky Practices to Avoid and How to Stay Secure
While the convenience of remote connect IoT device functionality is undeniable, it's crucial to acknowledge and avoid risky IoT remote access practices. Cutting corners to gain remote access to your IoT devices can leave doors open for lurking cybercriminals to sneak in undetected.
