IOT Security and Different Layers of Communication Protocol

In the previous Posts we were talking about the Reasons and the uses of IoT .Now we will talk about the Security parta nd it's connection.

Challenges and Issues With IoT

Issues:

Society: People, security

Environmental aspects

Resource efficiency

Pollution and disaster avoidance

Technological:

Architecture (edge devices, servers, discovery services, security, etc.)

Governance, naming, identity, interfaces

Service openness, interoperability

Connections of real and virtual world

Standard

Risks Of IoT:

Security: Increased automation and digitization creates new security concerns.

Consumer Privacy: Potential of privacy breaches.

Data: Lots of data will be generated, both for big data and personal data.

Storage Management: Industry needs to figure out what to do with the data in a cost-effective manner.

Server Technologies: More investment in servers will be necessary.

Data Centre Network: WAN links are optimised for human interface applications, IoT is expected to dramatically change patterns by transmitting data automatically.

Now Many companies are trying build IoT devices more secure. So its possible to have Secure IoT devices Near future.

Opportunity in IoT::Hype Cycle

Hype

as we can see the Hype Cycle stats of IoT along with Different Technology, The Red marked Internet of things suggest the Development sector which would open a gate for the the IoT Developer and create new start ups.

IoT Different Aspects::

Here in This The Things i.e. The sensors (Ir Sensors, cameras,Temperature Sensor, Ultrasonic Sensor,) and Actuator(Motor,Led,RGB etc) are connected to the The Processor(may be Conroller or MicroProcessors) which then connected with different Connected i.e. Wifishield,RF Module, Zigbee Module for distance communication. Which then goes to The Local network i.e. The near gateway the it travel sto the Internet That is Cloud then after towards then data centers i.e. Intelligent servers where the data would be Stored and processed for the transmission of data using Artificial Intelligence and Big Data /Data Analytics.where then the Data further Sent to the End Things for the respective which would be perform.
for e.g.: Taking Traffic light System in a city then first the End devices that is Cameras take the necessary data to the local network and then it would be sent to the Internet ,where then it goes to the city data center for the data manipulation that is what to do with these data should we sent weather report or accident abouth the road. the again after proceesing the data the daata is sent back to the proceesor/controller which then performs the respective task by commanding to the actuators.

Sensing And Processing Layer:

PIR Sensor, Camera(DIP),IR Sesnosr,Temperature Sensor(LM 35),

Processors/Controller: Raspberry pi, Arduino, Galileo,bluemix

Output Actuators:Motors,Buzzers,LED,LCD

Communication layers:

Protocol Stack:TCP/IP or OSI layer for communication

IP Transition:Dual Stack, header translation,Tunneling

MANETS:Mobile AdHoc network.

MANET:::>∃∃

MANET: A mobile ad hoc network (MANET) is a continuously self-configuring, infrastructure-less network of mobile devices connected wirelessly. Each device in a MANET is free to move independently in any direction, and will therefore change its links to other devices frequently.

Management layer:

The data will be stored and forwarded to the end devices i.e. Prcessor or controller which infact process these data by actuating these.

Big Data centre or Back end service

Data Centre:For processing and And then Directly Sends data to Cloud

Different Providers providing services for connecting your end devices .Microsoft Azure, PubNub, ThingSpeak, Temboo are different providers providing cloud services for real time connection between your devices.But i personallly prefer PubNub as its ease of use.

In the Next Post We would talk about how to Connect those devices using PubNub and its different keys .
Querry ?? drop your commnets

Thank you :)
