12 Common IoT Security Challenges and Solutions for Fixing Them

The Internet of Things, or IoT, is changing the way we live and work in the UK. Whether it is a smart speaker in your living room, a fitness tracker on your wrist, or sensors in delivery vans, IoT connects these devices to the internet so they can collect and share information.

It’s helping people and businesses work more efficiently and make better decisions. In the UK, more and more companies are starting to use IoT to improve how they operate.

From retail and healthcare to farming and logistics, IoT is opening new doors. But just like any growing technology, IoT also brings challenges. Business owners, developers, and IT teams are often faced with challenges related to IoT security.

If you understand these challenges, then it means you have taken the first step to solving them. In this blog, we will explore 10 of the most common IoT security challenges, solutions for fixing them, and how to avoid them.

What is IoT Security?

The Internet of Things (IoT) is a system of interrelated devices that are connected to the internet and can collect, share, and act on data.

So, what is IoT security?

IoT security refers to the methods, technologies, and strategies used to protect Internet of Things (IoT) devices and the data they transmit from cyber threats, unauthorised access, and malicious attacks.

IoT security is important because smart devices, like cameras, sensors, or home assistants, are always connected to the internet and often share personal or business information. Many of these devices don’t have enough safety features, which makes them easy targets for hackers.

If someone breaks into one device, they can often reach other connected devices or systems. That’s why it’s important to take steps like setting strong passwords, using secure internet connections, and updating device software often.

These actions help keep the devices safe and ensure the information they send stays private. Without proper safety, even one unprotected device can cause problems for homes or businesses.

What are the Main Challenges of IoT & Their Solutions?

The Internet of Things (IoT) has opened the doors to a connected world where devices talk to each other and work together. But with this rise in connected devices comes a whole new set of challenges businesses in the UK have to deal with.

Below, we will learn the most common IoT security challenges and how companies can overcome them.

1. Security Risks

The first most common IoT security challenge is related to security. IoT devices are the prime target for hackers and cybercriminals. These devices often serve as entry points for attacks on connected networks.

So, if these devices don’t have proper safety features, like weak passwords, old software, or no safety locks, hackers can easily break into them, steal data, and control the device remotely.

The Fix

Always change the default passwords and use ones that are difficult to guess. Turn on a two-step login where possible. Keep the device’s software updated to fix any known security problems.

It is also a good idea to use a secure internet connection, like a private Wi-Fi network with a strong password, rather than public or open networks. Taking these actions adds more safety layers to protect the devices from online attacks.

2. Device Compatibility Issues

Many IoT devices come from different brands and use different systems to run. When these devices can’t work well together, it becomes difficult to create a smooth setup.

When they don’t follow the same rules, sharing data or performing tasks as a team becomes challenging. This slows down progress and creates extra work for IT staff, who have to create workarounds or manage everything separately.

The Fix

To solve this, look for devices that follow widely accepted communication rules or standards. These standards help different devices understand each other better.

You can also use IoT management platforms that help bring all devices together in one dashboard, even if they come from different brands. This makes it easier to manage everything from a single place and avoid compatibility headaches.

3. Interoperability

This IoT security challenge is closely related to compatibility. It is about devices being able to share and understand information with each other. This is especially important when businesses use devices from different companies or need them to connect with older machines.

Interoperability is also a big challenge for IoT manufacturer, especially when their solutions rely on open-source technology. The problem isn’t open source itself but the lack of a central body to set clear standards.

This can lead to different companies or countries using slightly different versions, making it hard to mix technologies from different vendors or expand to new markets.

While this doesn’t affect every IoT system, some industries need to move faster toward using universal standards to make things work better together. Data sharing also adds to the difficulty since devices often use different formats, which makes communication between systems tricky.

Using common communication methods and data formats can help reduce the effort needed to get everything working smoothly.

The Fix

Using platforms and software that support open-source technology or common communication standards can help a lot.

These platforms act like translators, assisting devices to share data correctly even if they were not originally designed to work together.

Companies should also think about long-term compatibility when choosing devices, so they don’t face major problems later as they scale.

4. Data Privacy Concerns

With IoT devices constantly collecting data, from user behaviour to system performance, there is always a concern about how that information is being handled.

In the UK, businesses must follow rules like the GDPR, which protects the personal data of users. If a company fails to keep this data private, it can face serious legal trouble as well as damage to its reputation. This is a major concern, especially for devices in homes, hospitals, and workplaces.

The Fix

To handle this, data should be protected while being sent and stored, using encryption so others can’t read it.

Companies should be honest about the kind of data they collect and let users choose what they are comfortable sharing. Following local privacy rules can also help avoid legal trouble and build user trust.

5. Scalability Bottlenecks

Many businesses start with a small IoT setup, but they want to add more devices, locations, or users over time.

When their system isn’t ready to grow, they run into scalability issues. This can lead to slow performance, errors, or system crashes, which affect both productivity and customer experience.

Businesses might also find that tools which worked fine on a small scale now struggle to handle more difficult workloads.

The Fix

Using cloud platforms designed to handle thousands of devices makes it easier to scale without issues. These platforms can automatically adjust based on how many devices are connected.

It is also helpful to create systems that are modular, meaning new parts can be added without breaking the old ones.

6. Network Reliability and Latency

IoT devices rely on constant internet access to send and receive data. In many parts of the UK, network coverage can be weak or unstable.

This causes delays (known as latency) or interruptions, where devices stop working because they can’t talk to the rest of the system, making it one of the common IoT security challenges. In some cases, delays of just a few seconds can cause damage, like a traffic system failing to update in time.

The Fix

To fix this, use more reliable internet options such as wired connections in important areas or 5G for faster wireless communication.

Also, set up local backups or edge computing devices that keep things running even when the internet is down. This reduces waiting time (latency) and ensures key devices continue to work during network issues.

7. High Implementation Costs

IoT for business can cost a lot at the start. First, you need to purchase smart devices, like sensors, routers, and other hardware, and then you need to connect those devices through networks and possibly build or rent to store and manage the data requirements for those devices.

There are also costs for installing and maintaining the system. When you are a small business or a startup, these costs can be too much, especially with limited knowledge about potential ROI.

The Fix

The best approach is to start small. Focus on the most important areas that can benefit from IoT and expand slowly. Use cloud services instead of building your own infrastructure.

Renting or subscribing to services rather than buying everything outright can also reduce upfront costs. If you implement this solution, you can see that the savings from better efficiency often cover the money you have spent initially.

8. Shortage of Skilled Talent

There aren't enough people who know how to manage and run IoT systems. This talent gap makes it hard for companies to build and maintain successful setups.

This means a lack of trained staff who understand both the hardware and software sides of IoT can slow down projects or make it hard to resolve problems when they come up. It can also lead to poor security of the systems, which makes devices easier to hack.

The Fix

Invest in training your existing staff or work with experts from outside who already have the needed experience. Partnering with tech companies in the UK or universities can also bring fresh ideas and skilled help.

Building a knowledgeable team step by step is better than rushing and facing mistakes and regrets later.

9. Supply Chain Vulnerabilities

Most IoT devices are made up of different parts, like chips, sensors, and batteries. If even one of those parts is not secure, or if it comes from an untrusted source, it could become a way for hackers to get into the system.

This is called a supply chain vulnerabilities, which are also the IoT security challenges faced by many businesses, organisations, and manufacturers. Since companies don’t always control where every part comes from, it becomes hard to trust the devices.

The Fix

The solution for this IoT security challenge is to work with trusted suppliers and always have a backup vendor in mind. Store extra devices or parts when possible. Also, choose equipment that is easy to replace or upgrade.

10. Complex Integration with Legacy Systems

Many businesses already use older systems that don’t work with the latest IoT technology. Trying to connect new smart devices with these older tools can be difficult.

It may lead to system errors, delays, or extra costs. In some cases, the old system may need to be replaced completely, which often costs businesses more and also requires more of their time.

The Fix

Instead of replacing everything at once, use tools that help new devices “talk” to older systems. These tools act as translators and help make the transition smoother. Gradually updating the old systems over time can also make integration easier and help you save money.

11. Data Overload

IoT devices create a huge amount of data every second. If this data isn’t organised or understood properly, it can become overwhelming and useless. Too much information can slow down networks and make finding important patterns or problems challenging.

The Fix

Use data management tools that can pick out important details and ignore the rest. Dashboards that show only key information help teams stay focused. Cloud storage is also helpful for saving large amounts of data.

12. Power Consumption and Battery Life

Many IoT devices are placed in areas where it is difficult to reach them, like on rooftops, in the ground, or on moving vehicles.

These devices often run on batteries; if the battery runs out, it can stop working until someone replaces it. Frequent battery changes take time and money, and in some cases, they are just not possible.

The Fix

Choose devices that use less energy or have energy-saving modes. In some cases, solar-powered options can be used to keep devices running longer. It also helps to set up alerts that notify you before a device runs out of power, so you can replace or recharge it in time.
