[TBD]Understanding IOT environment

IOT device

A mundane object which has sensing, computing, networking and actuation(able to realise commands) capability.

Components of IOT

• Device

• Gateway

• Cloud

Edge computing

Gateway connected to IOT device gets command directly. Gateway uses local data for making decision.

The aim of Edge Computing is to move the computation away from data centers towards the edge of the network, exploiting smart objects, mobile phones or network gateways to perform tasks and provide services on behalf of the cloud.

Development boards

• Arduino UNO

  • raspberry pi

  • Intel Galileo (Arduino compatible)

  • Microsoft Azure IOT Starter kit (For Microsoft Azure built-in configuration)

• TI development kit

• Zepy module for home automation with Wi-fi module

Sensors

• InfraRed sensor

• Proximity sensor

Raspberry pi

Operating systems

• • Raspbian buster (based on Debian Linux)

  • Ubuntu

IDE for IOT development

Please use https://www.arduino.cc/en/guide/environment

Messaging protocol

MQTT is used for communicating with IOT device. PAHO is the python library for the same.

Means to connect device

• SSH

Challenges in IOT devices

• Real-time infrastructures cannot be brought down for security updates and patching

• Low-latency, proprietary protocols limit the ability to deploy antivirus and anti-malware software

• Embedded processors have limited processing power and memory to execute security software

• IoT devices have a small form factor, limited connectivity and are designed for very low power consumption

• Many IoT devices are physically accessible to the attacker
