With a wide range of devices and technology, the Internet of Things (IoT) is expanding quickly. According to analysts, the Internet of Things will reach its pinnacle of success in the upcoming years. But as IoT has gained popularity, the risk has also grown.

For IoT, which is an obvious target for hackers, security is the largest concern. There are countless instances where hackers used device flaws to enter a network and bring down the most popular services, as happened in 2016 when Twitter and other important platforms were offline.

Poor security measures on IoT devices pose a severe risk to both consumers and the devices themselves. You may learn more about the greatest security dangers and difficulties that IoT presents in this post.

Biggest IoT Security Challenges

Nowadays, not only people are connected to the Internet; devices are also connected to the internet for communicating with other devices and forming networks. The devices are keeping themselves updated every time with internet connectivity. IoT does wonders but its security flaws are a big challenge for the industry. Technology is no doubt very successful, but it has not matured in terms of security. It still has many security challenges from makers to the users like it has a lack of manufacturers' standards, users are not aware of using the technology, and lack of updating features, etc. So, if these issues are not be addressed then IoT will suffer a lot.

Biggest IoT Security Risks

Now that you've read about a 2016 security vulnerability, you can see that manufacturers' disregard for security was the root of the problem. They simply keep launching new gadgets with new technology. By doing this, they provide hackers access to the gadgets through an exposed edge. IoT security concerns are many.

  • New devices lack manufacturer’s attention on security

    Due to the rapid introduction of the devices in the industry, the manufacturers are just paying attention to the functionality but not on the security of the devices. So, cybercriminals attack the weak parts of the devices. The devices are also exposing themselves. For example, when two devices are paired using Bluetooth, they always remain as a paired device. Hence, the devices can be accessed with a Bluetooth key. This is the biggest security risk that IoT has. Another reason for this issue is that there are no specific security standards that the manufacturers follow. The manufacturers do care about security; they just add internet connectivity on their devices. Hardcoded passwords, insecure data transfer, hardware issues, lack of secure instruments, and many others are the security risks of IoT that the makers do not pay attention to.

  • Deficiency of awareness in the users

    Over time, internet users have learned how to protect their PCs and mobile devices. People now understand the value of virus checks and are aware that they shouldn't read scam emails. IoT is a new technology, though, and many people are not familiar with all of its words and capabilities. So, the IoT is susceptible to serious threats from manufacturers, consumers, and enterprises. Hackers target people as well as technology. Some consumers don't know much about the gadgets. As a result, they carry their jobs without considering the results.

  • Update management issues in IoT devices

    The insecure software is also a great security risk for IoT. The manufacturers, no doubt, sell their devices with updated software, but they must also have to take care of the proper updates needed to keep them safe. But as the people do not have much knowledge about the technology, they do not update the software when needed. The smart devices are utilized without the updates that leave a question mark on the security of the devices. Even when someone updates a device, he/she may have no idea that the updating file is safe or not. If it is not safe the hackers can get access to the sensitive information of the devices, which indeed is a very alarming situation.

  • Inefficient physical security

    This contributes to the IoT security threats. Both physically and online security must be implemented for the gadgets. There are external attacks that exploit security holes and cause annoyance for users and devices. In this case, danger is produced by both the makers and the consumers. The producers of low-cost devices don't care about security; thus, it must be difficult for them. On the other hand, consumers run the danger of leaving an Internet of Things device, such as a camera, unprotected if they use it outside their home. Therefore, actions must be taken to confront and address this security issue.

  • Botnet threats

    There is not a single malware that can cause a security threat for IoT devices. The hackers prepare a team of malware for a botnet attack so that it can excessively stop the devices to work or gather the information from the devices. The IoT devices are always at threat of the attack of malware. The malware does not have security updates as on the computer. That is why hackers can easily attack these devices.

    Being a IoT is just a step away. Check out the Internet of Things Training in Bangalore at 360DigiTMG and get certified today.

    There are many other security risks that IoT is facing like data integrity risks, multiple security challenges, someone hijacking the IoT device, industrial security threats, and many more. Due to all of the above-mentioned security risks, IoT is still in its infancy and has not been secured because people are not much aware of its functionalities.


As technology develops, there will be more challenging problems. The gadgets are being attacked by the hackers in novel ways. As a result, IoT security standards are required so that the manufacturers may produce the devices in accordance with those requirements. The use of a gadget should be prohibited if it does not meet the requirements. The hazards involved make the IoT's future uncertain. Therefore, there is a need for workable and ideal solutions to the security issues if IoT is to succeed in the future.
