Understanding the Internet of Things (IoT) and Its Risks
The Internet of Things (IoT) is changing the game for UK businesses, making day-to-day operations smoother, more efficient, and better connected. But with all this convenience comes challenges, like keeping your devices safe from botnets and other cyber nasties.
For business owners and IT managers, bringing IoT devices into the workplace isn’t just about upgrading your tech. Each gadget – whether it’s a smart speaker or a connected printer – could be a way in for cybercriminals if you’re not careful. Let’s explore how UK businesses can outsmart these threats and keep their smart devices secure.
Common IoT Cybersecurity Risks
IoT devices are great for business, but they can also be a hacker’s playground. Here are six risks to watch out for – and how to outsmart them
- Weak Passwords and Poor Access Controls
Default passwords like ‘admin’ or ‘12345’ are basically an open door for hackers. Only 1 in 5 people in the UK can spot a secure password.
What’s at play: Default settings are rarely updated, making devices easy targets for botnets.
- Unprotected Data
Sending data without encryption is like leaving your front door unlocked. No surprise 55% of UK adults have had their data stolen.
What’s at play: Many devices send sensitive info in plain text, making it easy for hackers to intercept. - Outdated Software and Malware
Old software is a hacker’s dream. 92% of UK financial firms still rely on legacy tech.
What’s at play: Unpatched devices are easy entry points for malware and botnet attacks. - Insecure Networks and Botnets
Open ports and unused features can turn devices into botnet soldiers. Botnets drove 37% of DDoS attacks in 2024.
What’s at play: Default features left on make it easy for hackers to recruit devices. - Dodgy Supply Chains and Insider Threats
Sometimes the problem starts before you even get the device. A public Wi-Fi attack at 19 UK railway stations showed how supply chains can be exploited.
What’s at play: Malicious firmware or insider access can compromise devices from day one. - No Monitoring or Response Plan
If you’re not watching your devices, you won’t know you’ve been hacked. 1 in 10 UK companies lack an incident response plan.
What’s at play: Without monitoring, botnet activity or other attacks can go unnoticed.
GDPR and IoT: Staying Compliant
If your business uses IoT devices to track things like employee habits or building occupancy, you need to handle that data carefully. The UK GDPR and DPA 2018 are clear: mishandling personal data can cost you up to £17.5 million or 4% of your annual global turnover. And since IoT devices are prime targets for botnets, protecting that data is critical.
These days, 65% of UK businesses collect personal data, and 50% collect non-personal data—but only a third feel confident they’re fully compliant. Staying on top of GDPR isn’t just about avoiding fines; it’s about outsmarting cyber threats, protecting your reputation, and earning customer trust.
NCSC Recommendations for IoT Security
The National Cyber Security Centre (NCSC) has shared simple steps to help UK businesses outsmart IoT cyber threats. Here’s how to stay ahead:
- Change Default Passwords
Passwords like ‘admin’ or ‘12345’ are basically a hacker’s dream. Switch to strong, unique passwords ASAP, and turn on multi-factor authentication (MFA) for extra protection.
- Keep Devices Updated
Outdated software is an open door for hackers. Automate updates to fix security gaps and keep your devices safe without the hassle. - Log and Monitor Activity
Track what’s happening on your devices – logins, updates, and changes. Secure remote logging can help you spot botnet activity or investigate issues quickly. - Separate IoT from Critical Systems
Keep IoT devices on their own network, away from your main systems. If one device gets hacked, the damage stays contained. - Use Secure Connections
Make sure your devices use encryption and secure protocols, especially if they handle sensitive data like customer or employee info. - Check for Weak Spots
Run regular security checks or penetration tests to find vulnerabilities before hackers do.
Smarter Security for Smart Devices
Smart devices are brilliant for business, but they can also be a magnet for cyber nasties like botnets. The good news? Outsmarting them isn’t rocket science. Follow the NCSC’s tips, stick to the UK GDPR rules, and make sure your IoT devices are locked down tighter than your biscuit tin.
