IoT: Is Security Still An Issue?


IoT refers to devices of everyday use that are now connected to the internet, receiving and sharing data with one another. This exciting new technology has been made possible by the advent of cheap microprocessor chips and the availability of wireless networks. The IoT has made the devices we work with smarter and more responsive to our needs e.g. motion-sensor enabled streetlights, driverless cars, etc.

Researchers at the International Data Corporation have predicted that there will be as many as 41.6 billion IoT enabled devices in the world by 2025 .

These devices will be connected to each other and will be sharing tonnes of data with each other. Apart from smart home & wearable devices, people will also leverage IoT in industrial & automotive sectors. Among all, security devices such as an intruder detection alarm and security camera systems will account for the second-highest use of IoT devices.

IoT & the security issues

As the IoT-enabled devices are being adopted more and more, the security concerns are also mounting. Hacked smart homes and police surveillance systems are some of the devastating security breaches that can be made possible by the IoT.

The smart home is probably where most consumers will be coming in direct contact with the internet of things and although they will make life much simpler and convenient, there are serious security concerns associated with it. These issues cannot be overlooked.

The sensors on IoT devices keep collecting private data and keeping this data secure is of the utmost importance for consumer trust. Unfortunately, attention to security details has been lacking and even the basic security measure like encrypting the data is not followed through.

IoT security has increasingly become a matter of concern after the occurrence of a number of high-profile cyberattacks where a common IoT-enabled device was used to infiltrate and attack the larger network the device was a part of. Many IoT devices lack the ability to fix the flaws in their architecture and such an inherent lack of security has now made IoT devices an easy target for hackers. Some smartwatches contain vulnerabilities that will enable hackers to not only track the location of the person wearing it but also eavesdrop on their conversation. Having a security infrastructure in place is critical to ensure the safety and privacy of networks with IoT devices connected to them.

With the reduction in the cost of making smart objects, these devices will become more ubiquitous and the risk would then be much more widespread. Since IoT connects the virtual world with the real world, any attack on an IoT device can have dangerous real-world consequences especially if such an attack is directed at critical industrial infrastructure.

As we are all aware, IOT sensors have the ability to collect enormous amounts of data from the user which...
