Internet of Things





What is Internet of Things?


Simply put, this is the concept of basically connecting any device with an on and off switch to the Internet (and/or to each other). This includes everything from cellphones, coffee makers, washing machines, headphones, lamps, wearable devices and almost anything else you can think of. This also applies to components of machines, for example a jet engine of an airplane or the drill of an oil rig. As I mentioned, if it has an on and off switch then chances are it can be a part of the IoT. The analyst firm Gartner says that by 2020 there will be over 26 billion connected devices... That's a lot of connections (some even estimate this number to be much higher, over 100 billion). The IoT is a giant network of connected "things" (which also includes people). The relationship will be between people-people, people-things, and things-things.


Key Components of IoT?

1. Sensors & Actuators : Inputs/Outputs

2. Connectivity : How things talk with each other

3. People & Processes : Logic and human intervention






Sensors & Actuators



Connectivity

The glorious world of Internet of Things. It all seems so nice and everything seems possible, but as a techie I have the bad habit of immediately searching for the flaws in everything that passes me. Now if there’s one consistent ‘flaw’ that I see returning when we are talking about Internet of Things, its connectivity.


There are several types of connectivity:


  • PAN: Personal Area Network
  • LAN: Local Area Network
  • NAN: Neighborhood Area Network
  • WAN: Wide Area Network









People & Processes

These networked inputs can then be combined into bi-directional systems that integrate data, people, processes and systems for better decision making.





IoT Security/ Privacy

Security

With data breaches more prevalent than ever, security is one of the most important factors to consider when selecting an IoT platform. For maximum data security, all connected devices and applications need to be authenticated with end-to-end security mechanisms to ensure that the organization and end users are protected from unauthorized access.

Additionally, enterprises should look for a platform that features end-to-end data encryption so that data is protected at rest and in transit – when it’s most vulnerable to theft. And finally, the Internet of Things platform should deliver regular security updates and demonstrate a commitment to ensuring that consumers fully understand their IoT security architecture.

Privacy

The full potential of the Internet of Things depends on strategies that respect individual privacy choices across a broad spectrum of expectations. The data streams and user specificity afforded by IoT devices can unlock incredible and unique value to IoT users, but concerns about privacy and potential harms might hold back full adoption of the Internet of Things. This means that privacy rights and respect for user privacy expectations are integral to ensuring user trust and confidence in the Internet, connected devices, and related services.


IoT Scalability

And finally, an ideal Internet of Things platform needs to offer scalability solutions. To meet an organization’s needs today and in the future, it needs to be able to handle a massive number of devices, as well as ensure security, reliability and performance as the number of connected things increases.


IoT Example

Examples of objects that can fall into the scope of Internet of Things include connected security systems, thermostats, cars, electronic appliances, and lights in household and commercial environments, alarm clocks, speaker systems, vending machines and more.

Businesses can leverage IoT applications to automate safety tasks (for example, notify authorities when a fire extinguisher in the building is blocked) to performing real-world A/B testing using networked cameras and sensors to detect how customers engage with products.





The Future of IoT

As far as the reach of the Internet of Things, there are more than 12 billion devices that can currently connect to the Internet, and researchers at IDC estimate that by 2020 there will be 26 times more connected things than people.

According to Gartner, consumer applications will drive the number of connected things, while enterprise will account for most of the revenue. IoT adoption is growing, with manufacturing and utilities estimated to have the largest installed base of Things by 2020.

Cross-site Request Forgery Protection in web applications via Synchronizer Token Patterns What is Cross-site Request Forgery Protection(CSRF)? This is a kind of attack and type of a malicious exploit of a website. We also name this attack as the one-click attack or session riding. This forces an end user to execute unwanted actions on a web application in which they're currently authenticated. This attack is mainly focusing on state-changing request, not theft data. As an example, if the user 'A' wants to transfer the 200$ to the bank 'B'.He needs to send a request to the bank 'B' and bank will send the response by authenticating user 'A'.There is an attacker he/she needs to fraud this money form user 'A'.what the attacker can do is he will create a malicious web link and send it to the user by forcing to click that link . while the user clicks the link for the transferring purpose but the thing is attacker was transferring the mon...

Cloud Computing

Cloud Computing What is Cloud Computing In the simplest terms, cloud computing means storing and accessing data and programs over the Internet instead of your computer's hard drive. The cloud is just a metaphor for the Internet. It goes back to the days of flowcharts and presentations that would represent the gigantic server-farm infrastructure of the Internet as nothing but a puffy, white cumulus cloud, accepting connections and doling out information as it floats. Usage of Cloud Computing 1. Infrastructure as a service (IaaS) and platform as a service (PaaS)   When it comes to IaaS, using an existing infrastructure on a pay-per-use scheme seems to be an obvious choice for companies saving on the cost of investing to acquire, manage and maintain an IT infrastructure. There are also instances where organizations turn to PaaS for the same reasons while also seeking to increase the speed of development on a ready-to-use platform to deploy applications. 2. Priva...
