Internet of Things-Connection Redefined


 
Imagine driving home after a long day of work. En route the car instructs the residence to automatically turn on the lights, prepare a hot bath, and download the latest Netflix series.

While this may seem like a line from a SciFi script, the future is more realistic than ever. Welcome to the world of IoT or Internet of Things.

Though not as popular as its famous counterpart, Artificial Intelligence, its penetration into the consumer market is indeed extensive.


What is IoT......

It is the term used to describe a device, or set of devices which are connected to the internet, and also communicate with each other. They can share data obtained from various sensors to a central hub, analyze it using  AI, and take appropriate actions. For example, a smart thermostat can read the room temperature, analyze the same, and adjust the heating system without any human intervention. Another example would be a smart camera which provides video footage when a movement is detected in the house. This can be done remotely even when the home owner is not present.


Beginning....

The invent of this tech is heavily contested with some claims to be as early as the introduction of  first long distance communication or the electromagnetic telegraph.

Others state that IoT emerged along with the advent of Internet. The first verified device which used this technology was a Coca Cola vending machine installed at Carnegie Mellon University, 1980. It send information related to device temperature, and inventories to a central server. 

Then came the introduction of RFID (Radio Frequency Identification) tags which were used to track device location using radio waves. A point here to be noted. RFID is different from Barcode which are parallel strips containing passive information. Barcode need to be scanned independently and a line of sight to communicate. Both these drawbacks are mitigated by RFID. 

 

  

 

 

 

Another example would be Wireless Sensor Networks (WSN) which are collection of sensors placed at different location across a industrial or residential complex. They then send information periodically to a central command which are stored in real time, and actions inserted.

 

Cyber Attacks and Privacy.....

Of course, the connected world brings the concern of hacking and data theft with it. There is a remote chance that unethical actors can steal data and use the same for unscrupulous activities. What if an outside actor gets data from a smart watch. The sensitive information regarding your health such as blood pressure, allergies can then be used for manipulation. Another example would be turning on the hallway or bedroom  camera capturing private moments which can be used for ransom purpose. 

Cybersecurity for IoT devices is slowly catching up, but due to fast acceptance rate need to speed up more. Any device connected to the internet or even remotely is prone to hacking as the Stuxnet worm has proved it.

Basic steps of prevention include regular software updates, antivirus and firewall installation.

 


The Future......

The future holds great promise as the IoT industry is said to total around $2.227 billion by 2028. Also decrease in hardware and sensor costs can increase the penetration rates.

Virtual Private Network (VPN) - Browsing Anonymous

  Privacy is a major concern when browsing the internet. Your data could be eavesdropped by hackers, companies targeting ads or even rogue state actors. What gets revealed would be personal browsing history, location monitoring, IP addresses to name a few. Enter the tech... Virtual Private Network or simply known as VPN is a technology used to prevent unauthorized access of your private data. Even if a hacker penetrates the network and get hold of data packets, all that is revealed is gibberish.  This is because all the information that passes through your device is encrypted and can be only revealed through a personal key.  Internet Service Provider Before going further, a knowledge of Internet Service Provider (ISP) is needed. They are the backbone of the World Wide Web. ISP provides each device with a unique IP (Internet Protocol) address, bandwidth allocation and network security. When a website is searched, first it goes from your device to the Router or Modem which...

Ransomware - Trojan in Disguise

  You log into the computer, and it boots up. But instead of seeing the welcome screen, you get a dialog box.  "Your data has been encrypted. To recover, pay $$ of Bitcoin." The message also has a countdown timer, which indicates a payment deadline.  Passwords, credit card details, personal videos/pictures all have been compromised. The hacker even threatens to leak everything online. What happened...... Ransomware is a type of malware that encrypts personal data and blocks access to a computer/network. To regain control, a ransom needs to be paid. Usually this is through Bitcoin, or other crypto currencies. On payment, a key is given, which decrypts everything, and returns access to the system.  However, you could be placed in a "Sucker's list" which is sold in the dark web. This can attract more ransomware attacks, in future. History.... Originating in the 90s, the attacks were first recorded in Russia. Since then, it has crossed into Europe and North America...
