Each protocol serves its own purposes in different IoT environments to ensure secure remote access for the user. Understanding how these protocols operate is crucial as they play an essential role in protecting internet connections with connected devices.

Secure Shell (SSH)

Secure Shell, commonly known as SSH, is extensively utilised for securely connecting to and managing IoT devices based on Linux and Unix. It is a reliable protocol that ensures secure access and control of these devices. By establishing an encrypted connection between the user’s computer and the IoT device, it enables safe remote management even over unsecured networks. This adds another layer of protection for data communication while accessing public or unsecured networks by reducing risks such as interception or unauthorised entry.

One notable feature of SSH is its ease-of-use when deploying with headless devices quickly. It provides a secure means to communicate with remote servers, networks, and other connected devices through SSH tunnelling techniques like local port forwarding, remote port forwarding, and dynamic port forwarding in bypassing firewalls effectively.

Adequate authentication measures should be implemented via command-line configurations while using SSH to ensure only authorized personnel have secure access to remotely manage various connected devices.

Virtual Private Networks (VPN)

VPNs, also known as Virtual Private Networks, offer a secure means of remotely accessing IoT devices. By creating connections that appear to be part of the same network as the devices themselves, VPNs are particularly beneficial in professional settings where managing sensitive data and direct remote connections is crucial.

For optimal performance, it’s recommended that a VPN has minimal resource requirements (such as only using up a few MBs of RAM) and can run on Linux kernels 3.x or higher. Additionally, it should support popular protocols for remote access such as Remote Desktop Protocol (RDP), Secure Shell (SSH), Web-Based Access, and Remote Access Software.

Although they provide enhanced security measures for connecting to devices remotely, VNPs may have some potential vulnerabilities. For example, a connection might remain open indefinitely, which poses significant risks. To address this issue, some solutions like Teleport use short-lived certificates set to expire daily. This ensures automatic termination of all connections and requires users tore-authenticate every time they need continued access, resulting in improved overall security for any connected devices.

Remote Desktop Protocol (RDP)

Remote Desktop Protocol (RDP) is a protocol used for remote connectivity to IoT devices running on desktop operating systems. It allows convenient and flexible access to these devices from remote locations, making it an ideal choice for projects requiring use of the device’s desktop interface.

To enable RDP-based remote access, proper firewall rules must be configured beforehand. This step may require technical expertise but is essential for ensuring secure and efficient connection with the desired device or devices.
