More and more enterprises are beginning to embrace IoT technology and the security vulnerabilities that arise as a result of it. The use of the internet so as to enhance the capabilities of standard devices such as computers, smartphones, laptops, etc has brought in a welcome change and has set the path on the road to technological innovation.

These IoT devices are integrated with high definition technology so as to enable it to communicate and interact across the internet, smoothly. This enables for it to be managed and controlled remotely, without you ever being needed near it.

The devices then make use of the information that is gathered, analyze them and take action based on the analyzed data. However, data in the wrong hands can spell serious trouble, and this is one of the primary IoT security challenges that have kept IoT security companies up at night…

We shall take a look at some of the leading roadblocks that we will need to address with IoT becoming more mainstream:

An Increase In The Botnets

With the IoT tide washing over society, there have been instances of botnets- an increase in them have been noticed in the past couple of years. Botnets exist when hackers remotely control internet-connected devices and use them for purposes that are illegal. The damage that can be done with the information that they pick up is truly frightening. Before you know it, your smart home can be completely compromised and your bank account emptied. For an enterprise, they could have their devices that are co-opted to be compromised by a botnet without them ever getting a scent of it being there.

The reason that they go undetected is that enterprises may not have real-time security solutions to track and monitor them, leaving them wide open for attacks.

Small Scale Attacks In IoT Devices

Security professionals are concerned and focused primarily on large-scale attacks, but what is scary is the fact that small scale attacks are what could pose a larger IoT security challenge. With devices being interconnected, a chink in the armor can cause the entire system to be breached. A small-scale attack is far more difficult to detect, and there is a high chance that the organization or enterprise may not even have realized that a breach has occurred. One of the many ways that hackers can breach enterprise tech is via camera and printers.

A Rise In IoT Devices

The landscape has changed a lot in the past couple of years, with an increase in the number of IoT connected devices. The numbers of smartphones and computers have skyrocketed in the past decade, and there are close to 7 billion devices all over the globe, which could bump up to 30 billion by the time we reach 2025. More connected IoT devices mean that there will be higher security vulnerabilities and ever growing challenges for professionals. 

IoT Financial Related Breaches

There are certain establishments and enterprises that make use of IoT devices to pay electronically, and there is always the risk of hackers swooping in and stealing money. Some of the organizations have a machine learning algorithm so as to stop financial fraud even before it is attempted via a connected device. This solution is not found in many organizations, and it is yet to be completely used in every single place.

Outdated Security Features

An interconnected legacy system can pose a big threat and the technology seems out of place. With a breach in the legacy technology, it could manifest from a breach in an IoT device, especially those that lack modern standards of security.

Encryption Is Lacking

There is no doubt that encrypting data is one of the best ways to prevent the wary eyes of hackers from befalling them. The connected IoT devices lack the storage and the processing capabilities that are needed to encrypt data and send it across. This lack of proper encryption means that hackers can easily manipulate the algorithm that was designed to protect. Unless IoT security companies do something to resolve and close in the security risk, they will be leaving themselves wide open for attack.

Difficult To Predict Threats

One of the tasks of security professionals is to predict future threats, and not only act when the breach actually occurs. Some enterprises however lack the robust and well-oiled management system that could monitor and keep track of activity and provide much needed insights into potential threats that could happen. If the enterprise cannot foresee the adversity or potential breach, then it will fall victim.

User’s Privacy

Enterprises have the responsibility to protect user data, which applies to both internal and external users. This is true for those who make use of IoT devices. When a breach occurs the private data is compromised, and the enterprise’s cred takes a beating. IoT security challenges can be overlooked and must be thoroughly scrutinized and improved.

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:
