How secure is Internet of Things?

How secure is Internet of Things?
Internet of Things is a new word in the industry. It has been gaining a good popularity over the years however people are still concerned about how great it actually is? Internet of Things refers to a huge network of connected devices sharing and communicating data with each other, but is this communication safe and secure from an outsider’s attack, or is this communication kept 100% private? These questions are yet to be answered.
A lot of people have their concerns about the communication not being secure and completely private. However, as work is being done in developing this technology, research is also being done on keeping this technology safe and secure for the users. IoT security is the field which deals with the security of devices connected in this huge network. This becomes a bit of a challenge when security is given the least property in the design phase of any application however gradually the trend is changing and now security ash become one of the top priorities of any application or machine.
What are the security challenges?
With such huge networks, the challenges to keep them secure are also huge. The problems mostly arise during the designing of the product because mostly the designer is more interested in getting the product ready than analyzing its security and how it can be destroyed. It leads to poor security of the application. The very common mistake that is done is using default or unsafe passwords which give hackers a very easy way to enter into the application.
Right now, there are 23 billion IoT devices that are connected with each other, this number is yet to rise to 30 billion by 2020. With such an increasing number of devices, the number of malware and viruses is also increasing which of course increases the security challenges. Cameras have become a very easy way to get into any place and retrieve sensitive information. Laptops, phones, cameras, smart watches all such smart devices are an open attack for viruses and malwares.
Blockchain which has gained so much popularity over the last few years is also very attractive for the hackers and they are not lagging behind in making money out of this. The blockchain app development has given the hackers a very easy way to get the sensitive information such as usernames, passwords and private keys and then use this information for their own benefits.
The IoT devices are flooding into the market and they are collecting huge amounts of data every day. Such huge amount of data will eventually become very difficult to handle. The automation that has been brought by IoT itself is a good thing, however the risk involved with such automation cannot be ignored. Taking an autonomous decision that will be affecting millions of lives especially in healthcare is a very risky decision.
To deal with all these and many more security challenges a strict legal and regulatory framework is required to ensure that right decisions are being taken.
How did IoT security get this attention?
There is no doubt that before some incidents happened security was never the top priority of application developers. However, some notable incidents brought the attention towards this side of IoT.
The very famous Mirai botnet which disabled the websites like twitter, Amazon, Netflix, and the New York times for several hours in 2016. The attack was conducted through IoT devices which included the cameras and the routers.
In 2013 the first IoT botnet was discovered and it was later revealed that 25% of this botnet consisted of smart TV’s, and other home appliances like baby monitors.
So, the security breach can happen anywhere, it is not just the computers that can be hacked, your TV, your car, your home appliances, all appliances that are working under the cloud of IoT are at a risk of attack.
Internet of Things is an astonishing technology however if it is does not prove itself to be safe and secure for the users, it might not be very well received by the world after some time.
