How do I secure an Arduino IoT sensor node?

Hi all!
In a sensor network utilizing Arduino nodes, what security practices should be implemented to protect the data collected and transmitted by these nodes? Address potential threats related to sensor data integrity and confidentiality, and discuss encryption techniques suitable for Arduino sensor nodes.

Hi,@nour_huda to ensure the security between Arduino Sensor Node or any other IOT devices. I'd suggest using a protocol with security encryption. Let's say if you decide to use HTTP/MQTT/Websocket then use them with SSL/TLS encryption like HTTPS/MQTTS. If using wireless protocols like Zigbee, and Bluetooth then make sure to use AES encryption 128-bit lightweight. Note that Bluetooth and other protocols use passcodes to increase security while pairing devices. This additional authentication mechanism provides an additional layer of security. Also, make sure to implement proper checksum mechanisms in code to ensure data integrity.

I suggest using tools like Wireshark and analyzing network packets to detect the vulnerability. A regular security audit will help in the long run. Also, use Penetration Testing from professionals to ensure data confidentiality. Hope this will help.
