What is IoT tunnelling?
IoT tunnelling enables secure connections between devices over private and public networks, bypassing traditional network barriers. It is crucial for enabling remote access to devices behind firewalls, improving operational efficiency and security.
Technological foundations of IoT tunnelling
IoT tunnelling uses advanced technologies for secure communication over potentially unsecure networks. Transport Layer Security (TLS) and Secure Shell (SSH) are key to this technology, safeguarding data as it traverses across networks.
How IoT tunnelling works
Secure protocols such as TLS in IoT tunnelling ensure encrypted data transmissions, maintaining high security. These protocols establish secure connectivity over untrusted networks, helping to protect against data breaches and cyberattacks.
Local proxies play a key role in IoT tunnelling. They act as intermediaries between IoT devices and the cloud, facilitating connections without altering network firewalls. This setup allows devices in restrictive network environments to communicate with external servers and applications, enhancing connectivity without compromising security.
Security enhancements & features in IoT tunnelling
IoT tunnelling solutions incorporate robust security features to safeguard data and ensure communication integrity. These security features include…
Encryption & token management
Encryption is foundational to IoT tunnelling security. Data transmitted through tunnels is encrypted using TLS, ensuring intercepted data cannot be deciphered. This maintains confidentiality and integrity as data moves between devices and networks.
Token management is also critical. Security tokens are digital keys that authorise and validate communication between devices and servers. These tokens are carefully managed to prevent unauthorised access:
Secure bi-directional communication involves several measures:
