What Does ‘Security and the Internet of Things’ Really Mean?
Security and the Internet of Things refers to the protection of internet-connected devices and systems from cyber threats. As the number of devices connected to the internet grows, so does the risk of data breaches and other security vulnerabilities. These devices, often called IoT devices, can include everything from smart home appliances to industrial control systems.
Ensuring the security of these devices is crucial to prevent unauthorized access, data theft, and other malicious activities.
This requires robust security measures, such as encryption, firewalls, and regular software updates, to safeguard both personal and public networks.
What’s the First Thing You Should Do to Secure Your IoT Gadgets?
The Internet of Things is a double-edged sword, brilliant yet brittle. Security and the Internet of Things (IoT) to transform our world is matched only by the risks it brings. IoT security challenges, ranging from vulnerable devices to devastating breaches, are real but not invincible.
1. An open door? Change your device’s default password now.
When you get a new smart device, it usually comes with a simple password set by the factory. These default passwords are often easy to guess, like “1234” or “admin.” Hackers know this and try these passwords first to get into your device. If you don’t change the password right away, your device is left wide open to anyone with bad intentions.
For example, if your smart camera’s password is still “admin,” a hacker can easily access the live feed and watch your home without permission. To protect yourself, pick a strong password that mixes letters, numbers, and symbols. It doesn’t have to be hard to remember something like “SunnyDay!2025” is much safer than “password.” Changing the password is the easiest and most important step you can take to secure your smart devices.
2. Updates are your device’s safety net: don’t ignore them.
Software updates fix security problems and help protect your devices from hackers. When a company finds a hole in the device’s defenses, it sends an update to patch it. If you don’t install these updates, your smart device stays vulnerable.
For example, a smart thermostat had a security flaw that hackers used to control heating in people’s homes.
Turning on automatic updates or checking for updates regularly makes sure you get these important fixes without thinking twice. This simple habit keeps your devices safer every day.
3. Keep your smart gadgets on a separate network.
Putting your IoT devices in a different like a guest room, for your devices. Wi-Fi network means that if one device gets hacked, the bad guys can’t get to your phone, laptop, or other important stuff.
Think of it like having a guest room in your house: if guests cause trouble, they don’t get into your main rooms. For example, if your smart fridge is on the guest network and someone hacks it, your personal computer on the main network stays safe. You can ask your internet provider how to set up this separate network, often called a guest or IoT-only network.
4. Turn off what you don’t use: Every closed door helps.
Many smart devices have cameras, microphones, or voice assistants that listen and watch. If you don’t need these features all the time, turning them off can block hackers from spying on you.
For example, parents who turn off baby monitors when not in use protect their family’s privacy better.
Check your device settings for features you can disable, so you only keep what you really need.
5. Not All Brands are Equal: Pick Smart Devices Built for Safety.
Some companies build devices with better security than others. Trusted brands follow strict rules and add extra protections, like special chips keep your data safe.
For example, a well-known brand might include a secure element that stops hackers from stealing your info, while cheaper brands might skip this.
Look for products certified by groups like the IoT Security Foundation or recommended by government agencies like DHS or CISA. Reading reviews and checking these certifications helps you buy safer devices.
6. Backups are your safety net when things go wrong.
If your smart device breaks or is attacked by hackers, having a backup means you can restore it quickly without losing all your settings or data.
For example, if you set up your smart home lights and schedules, backing up this info lets you get everything back fast after a problem.
Check if your device allows backups and make it a habit to save your settings regularly. This small step can save a lot of time and worry.
