Today, we’re diving into a topic that doesn’t always get the spotlight it deserves – but affects every smart device you own.
We’re talking about security in IoT.
From smart fridges to connected cars, the Internet of Things is growing fast.
By 2025, there could be over seventy-five billion connected devices. That’s more than nine devices for every person on Earth.
But with great connectivity comes great risk.
In today’s episode, we’ll explore the hidden threats behind IoT technology, how these devices can be exploited, and what we can do to stay secure.
Let’s get started.
First, what exactly is the Internet of Things?
IoT refers to everyday objects that connect to the internet and exchange data.
Smart TVs, fitness trackers, home assistants, surveillance cameras, factory machines – all of them fall into this category.
These devices collect, send, and sometimes act on data.
They’re embedded in our homes, our cities, and even our bodies.
And that’s what makes security such a big issue.
Most of these devices weren’t originally designed with security as a priority.
They’re small, cheap, and often have minimal processing power – which makes it harder to add encryption or advanced protection.
Let’s talk about some of the most common IoT vulnerabilities.
First, default passwords.
Many users never change them, and attackers know it.
Hackers often use automated tools that scan the internet for devices still using factory credentials.
Second, poor or no encryption.
Some devices transmit data – even personal or sensitive information – without encryption.
That means anyone snooping on your network could see what’s being sent.
Third, outdated software.
A lot of IoT devices don’t get regular updates or patches.
Once a vulnerability is discovered, it often stays open for years – giving attackers an open door.
Then, there are botnets.
The most infamous one? Mirai.
It hijacked thousands of IoT devices and turned them into an army for DDoS attacks, taking down major websites like Twitter and Netflix in 2016.
And let’s not forget physical access.
IoT devices installed in public spaces – like street cameras or parking sensors – can be physically tampered with or even stolen.
Now, here are some real-world examples that show how dangerous this can be.
In 2015, cybersecurity researchers remotely hacked a Jeep Cherokee.
They controlled the steering, the brakes, even turned the engine off – all through a vulnerability in the car’s entertainment system.
Another case involved smart baby monitors.
Hackers accessed live video feeds, watched families, and even spoke to children through the speakers. Terrifying, right?
In healthcare, IoT is literally a matter of life and death.
Medical devices like insulin pumps and heart monitors can be targets.
One hospital in Germany suffered a ransomware attack through its IoT infrastructure, and a patient tragically died due to the delay in care.
So, why is securing IoT such a complex challenge?
First, the sheer number of devices.
Millions – if not billions – of devices are already out there, with more added every day. Many are cheap and disposable, with no security maintenance plan.
Second, lack of standardization.
Different manufacturers use different hardware, software, and protocols.
There’s no single set of security rules everyone follows.
Third, speed over safety.
Companies want to be first to market – which means security often takes a back seat to speed and cost.
And last but not least – user awareness.
Most consumers don’t think about cybersecurity when buying a smart light bulb or a Wi-Fi coffee maker. But those devices can be backdoors into entire networks.
The good news is – solutions exist.
Here’s what you can do:
Always change default passwords – right after setting up any new device.
Segment your network – put your smart devices on a separate Wi-Fi network if possible.
Buy from trusted brands – and make sure they offer regular updates.
Keep firmware updated – enable automatic updates if available.
Turn off features you don’t use – if you don’t need remote access, disable it.
Use strong encryption and firewalls – especially for industrial or commercial use.
And on the industry level, governments are stepping in.
Laws like California’s IoT Security Law are pushing for minimum security standards.
There’s a growing movement toward “secure by design” – where devices are built with security baked in from the start, not bolted on later.
As we wrap up, let’s remember this:
The Internet of Things isn’t going away.
It’s getting bigger, smarter – and more essential to how we live and work.
But every connected device is also a potential entry point for an attacker.
Securing IoT isn’t just about protecting gadgets.
It’s about protecting homes, hospitals, infrastructure – and people.
