The scope of IoT is now being utilized by a large number of businesses for automating their processes. It is also widely used in many other fields including education, healthcare, and even in the agricultural sector. This new technology has introduced a large number of possibilities, however, it also comes with some challenges too. Therefore, through this article, we introduce some important IoT security challenges and their solutions.

IoT Security Challenges

IoT creates an interconnected network of different devices and systems including computing devices and other digital and mechanical machines. Most IoT systems have sensors that are used for collecting, transmitting, and receiving data. In addition to this, IoT applications will use software and Wi-Fi network to send and receive data via the internet. Therefore, most of the components used in IoT systems are vulnerable to security attacks.

Different components used in IoT systems can create a medium for the attacker to introduce malware or other malicious programs that can be used for compromising the security of the system. Therefore, your IoT systems are vulnerable to security threats. The following are some of the common IoT security challenges that can compromise the security of your systems.

Scan And Take Over

It needs to ensure high security for your IoT systems and applications. If the authorization and authentication processes used here are weak, then the attacker can easily take over your system. Also, if you are using poor encryptions and poor password protection because of the lack of enough hardware resources to execute complex programs, it will be easy for an attacker to enter the system, control, and finally take over it.

Distributed Denial Of Service (DDoS)

When the request traffic sent to an IoT system is very huge, it won’t be able to handle it. In this case, the target host will go down and the system will become unresponsive. If the system is connected to the internet, it will be possible for the hacker to send a huge number of requests from multiple sources to bring the system down.

Spam Attack

If the IP is connected to the internet, then other IP addresses will be able to easily send malware attacks to the IoT system if it has no security.

Interception Of Messages Using Spyware

As a large number of IoT systems usually have low resources, then it might not be possible for them to enable encrypted communication using security mechanisms such as TLS. This will compromise the system, as spyware will be able to read the data sent over the network layer, and it will be also possible for such malicious programs to manipulate the data as per their requirements.

Vulnerable 3pp Libraries

If the 3pps that have been attacked previously enter the system via system updates, then they can highly compromise the security of the system. Therefore, it is important to make sure that you use secure 3pps for your IoT applications.

Injection Attacks

Different web applications including IoT are susceptible to such attacks. Here, a request will be added to the existing one that can compromise the security of the system. XML and SQL are some forms of injection attacks.

IoT Security Solutions

IoT systems are vulnerable to a large number of security threats. Therefore, it is important for you to ensure their safety for protecting your data. There are certain measures you can adopt to ensure the security of your systems, some of them are mentioned below:

Regularly Update The System

Update the IoT applications regularly so that it will help you to make sure that the system protection is up-to-date. It is important to protect the data in all areas including confidentiality, integrity, and availability. This should be ensured across different surfaces including device, application, network, and sensor tier. In addition to this, if the devices are also connected to the cloud, then the communication has to be secured.

Secured Communication

The communication between the systems must be secured using TLS or other similar protocols for ensuring that the security of the systems is not compromised.

Authentication And Authorization

Password protection is important for IoT systems and they should be highly secured for avoiding the systems becoming vulnerable to brute force attacks.

Monitor And Detect

Run constant scans over the applications for detecting the presence of different threats. Also, ensure that other preventive mechanisms are also in place that can be useful to avoid attacks.

Data Integrity

Data protection is a compulsory measure for securing your systems. Make sure that all sensitive and confidential data is encrypted while transmitting and storing.

Secure Application

All the applications that access the IoT systems must be fully secured so that it will be possible for you to make sure that they are not compromising your security.

IoT systems are vulnerable to security attacks. Therefore, it is important to ensure that your system is protected well to avoid the compromising of system security. So you have to monitor your applications regularly for detecting the presence of different threats and should adopt preventive measures to protect your data and system.
