With these positive-looking estimates, the demand for IoT app development is bound to grow too. After all, companies are eager to leverage emerging technologies that can help their businesses prosper.

However, it’s imperative for organizational leaders to understand that despite the vast benefits the Internet of Things may deliver, the growth of connected devices can also pose a security challenge.

So, that’s the subject we will focus on today. Specifically, we’ll cover the most common IoT security concerns and ways of reducing them so that your company can follow the requirements and pursue development in the safest way possible.

Top 6 IoT Security Challenges Business Leaders Should Be Aware Of

Let us preface this section by saying that there is a lot of good that can come from implementing the Internet of Things technology across all kinds of industries. It can improve productivity, enhance the quality of services, and even reduce operational costs.

Thus, it’s no surprise that IoT adoption is growing within vastly different business sectors. For example, healthcare organizations are relying on IoMT solutions to refine the patient experience. Similarly, manufacturing companies are embracing IIoT software to automate internal processes.

However, as is the case with any emerging technology, there are risks that come with developing IoT-powered software. Typically, these challenges are security-related due to the many devices that communicate via the Internet and thus create new opportunities for cyberattacks.

So, let’s take a look at the six most common IoT security problems you might face.

1. Technology Novelty

Given the novelty of IoT technology, most users are largely unaware of the cyber security best practices that should be followed. While the majority of people working in the modern world know how to safeguard their computers and smartphones, very few can say the same about IoT gadgets they might come into contact with.

For instance, employees in firms that purchase IoT-enabled software might be unaware of how to use it securely. Thus, making them excellent targets for hackers who want to compromise the integrity of an IoT solution and use it for their own gains.

Given that the human factor can’t really be avoided, it’s imperative for businesses to educate their employees on how to use IoT-powered devices and the corresponding software. That way, IoT security risks will be minimized, and you can go on reaping the benefits of innovation without over worrying about it being threatened.

2. Outdated Operating Systems

Another common IoT security challenge stems from the fact that connected devices aren’t always running on the most up-to-date version of an operating system. This happens when manufacturers or custom hardware engineering companies don’t regularly update the software after it’s been launched. Or, only provide updates for a short period of time.

Unsurprisingly, as time passes, system vulnerabilities emerge. If they aren’t swiftly tackled by a thorough OS update, malware and various cyberattacks can quickly infiltrate and threaten the stability of your solution.

Thus, it’s essential for operating systems of IoT devices to be regularly updated so that new security risks can be prevented.

3. Lack of Built-In Security in Devices

Unfortunately, IoT devices usually come without integrated security measures in place. There are no built-in antivirus programs or encryption protocols to protect the system. Needless to say, this increases the chances of malware and ransomware infiltration, data theft, and other IoT security issues that companies want to avoid.

Hence, consider relying on the power of cryptography to safeguard the sensitive information you process. Or, embrace innovative technology like blockchain to prevent data tampering and have the ability to quickly shut down compromised devices in an IoT network.

4. Unreliable Deployment Locations

Often, IoT devices are deployed in public places and remote locations that might be easy for an attacker to physically access. This poses a significant IoT security risk since the gadgets can be tampered with once they’re installed.

For example, the memory card might be removed and its contents investigated to gather information that can help facilitate future remote attacks. Or, a USB drive with malware can be inserted to threaten the security of the entire IoT solution.

Thus, it’s important to work with manufacturers who build highly secure sensors and transmitters. Make sure to ask how exactly a device’s physical security is ensured. Additionally, if possible, instruct employees or end-users at the location to monitor the devices and limit easy access to them.

5. Use of Default Passwords

Another major threat to IoT security is the use of default passwords provided by device manufacturers. Typically, constructors will ship the hardware with rather simple login details, and consumers may not remember to actually change them.

Of course, this makes devices vulnerable to brute-force attacks and general hacking attempts. So, if you want to avoid this IoT security problem, make sure all employees adhere to strict passcode management policies and avoid weak password combinations.

Additionally, consider using various SSH security features and limiting logins for specific IP addresses and IP ranges. These IoT security standards ought to help you minimize risks and use your solution without fear for its safety.

6. Botnet Attack Potential

The last IoT software security threat that we’ll discuss today are botnet attacks. You see, one connected device that’s infected with malware might not pose an enormous threat. However, an ensemble of them can bring down an entire network.

Given that IoT devices are Internet-connected, they’re ideally suited for botnet strikes that leverage compromised gadgets to perform DDoS attacks, gain access to confidential information, or carry out other malicious activity.

To avoid facing this type of problem, it’s important to keep your infrastructure up-to-date, monitor network usage to spot unusual activity, keep track of failed login attempts, and generally adhere to IoT security best practices.
