IoT Security: Challenges, Solutions & Future Prospects

With rapid technological innovations, the Internet of Things (IoT) concept is emerging and evolving rapidly. There are a growing number of IoT devices entering the world, expanding the use of the leading-edge on-demand for IoT app development. The Internet of Things can be defined as a network that enables things around us to interconnect and communicate with one another such as smartwatches, smart T.V, smart mobile, and more. These IoT applications have the potential to add value to businesses, governments, and consumers.

However, with the advent of IoT and its use in society and industries, there has also been an increased concern over the security of IoT app development. These IoT devices are connected to the Internet and can be hacked like any other device connected to the Internet. Therefore, developing an in-depth understanding of IoT cyber security issues and implementing strategies is essential prior to adopting IoT.

In this article, we are going to cover security challenges for IoT, solutions & prospects. So keep reading!

1. Inadequate Testing And Lack Of Updates

When it comes to providing proper testing and timely software updates, tech companies are often very careless during the Internet of Things IoT app development. Due to the rapid growth of the Internet of Things market, many manufacturers are in a hurry to create and release their products without testing. This means that a device that was once considered safe when customers bought it for the first time becomes uncertain and ultimately prone to hackers and other security issues.

In some cases, the only updates provided relate to shorter periods. And since hyperproduction of devices is also a reality, they skip these updates to focus on the new generation of devices and urge people to switch to them. Consequently, your IoT device with outdated software may be subject to countless malware and hacker attacks and other security vulnerabilities.

To protect the IoT security issues, regular automatic updates are critical. It is the responsibility of the manufacturer to update the device software as soon as vulnerabilities come up and some malware attacks become prevalent.

2. Botnet Attacks

A malware-contaminated IoT app poses no real danger; it’s an assortment of them that can reduce anything. To run a botnet attack, a programmer makes a multitude of bots by piling them up with malicious software. And also guides them to send a large number of requests each second to reduce the target.

A significant portion of the uproar about IoT security risks began after the Mirai bot attack in 2016. Various distributed denial of service attacks using a large number of IP cameras, NAS, and home switches were corrupted and coordinated in order to reduce the type of support that DNS offers.

3. Problem in Device Update Management

Another source of IoT security risks is unstable coding or firmware. Even though a producer can sell a gadget with the latest programming update, it is virtually inevitable that new vulnerabilities will come out.

Updates are basic in maintaining security over IoT gadgets. They should be refreshed right after the identification of new weaknesses. In any case, like contrasts and mobile phones or PCs that get programmed refreshments, some IoT gadgets continue to be used without critical updates.

4. Hijacking IoT Devices

IoT devices with low-security measures may become ransomware targets. Ransomware is malicious software that doesn’t destroy your sensitive documents- it encrypts and blocks access to sensitive user files. Then the hijacker who has infected the device with malware demands ransom money from the victims to unlock their files. This security threat could put wearable technology, healthcare trackers, smart homes, and other ecosystems at great risk in the future.

Ransomware attacks can also completely disable devices and steal users’ data. The rapidly increasing number of IoT devices worldwide will make this particular IoT security problem unpredictable in terms of possible permutations. Nevertheless, since most IoT information is stored in the cloud, this malware may not have valuable data to lock. Hence IoT development can secure personal data.

5. Security and Privacy Challenges

With IoT, large numbers of devices are interconnected. Even a poorly designed device may cause security errors such as data theft and the potential for hacking other devices will increase as well. Data is constantly exploited, transmitted, stored, and processed by large companies through a broad range of IoT devices. These include smart televisions, loudspeakers, and lighting systems, connected printers, HVAC systems, and smart thermostats.

This also raises concerns about data confidentiality, as an enormous amount of personal data is collected by IoT devices. Sometimes, the end-user may even be unaware of the data that devices collect from them.

You must establish compliance and confidentiality rules which censor and anonymize sensitive data before storing and separating IoT data payloads from data that can be used to identify us personally. The cached data, which is no longer required, must then be disposed of securely.

Future of IoT Things

The Internet of Things Portable appliances is the future. Today, using a smartwatch you can control your car to automatically park and lock or open doors. Your portable device can also identify hazards around you. We already have devices that follow our activity and exercise patterns.

In the near future, we could also be able to easily monitor our calorie intake and diet habits automatically. So it’s going to be easy, but it’s hard to make it easy. Below are a few examples of IoT handheld devices that are already available on the market.

  • Sync Smartband Activity Tracker
  • Fitbit Surge Smart Watch
  • Hicon Wearable Smart Bracelet
  • Beddit Sleep tracker

It’s a clear indication that the IoT is the next big thing. Many leading IoT app development companies have already developed innovative products using the Internet of Things. Not only for large businesses, but IOT has also provided many enormous opportunities for many startups as well.

Wrapping Up

The Internet of Things has made people’s lives straightforward and comfortable. It has made things very convenient for people. The size of the Internet of Things will certainly rise dramatically in the future.

However, as the use of the Internet of things has increased, so has the threat to security. We should therefore be cautious about providing details on the Internet platform. However, we can see that many measures are being taken, but it is essential to keep your data safe.
