Frequently asked questions about IoT security?

IoT stands for “Internet of Things.” An IoT device is any device that can take in information and connect to other devices on a network to exchange this information. WiFi-enabled security cameras, thermostats, smart speakers, and computers all make up a network.

And while having everything connected to the internet can be convenient and easy, these devices are vulnerable to malware and other malicious attacks, just like any other internet-connected network.

As the Internet of Things continues to grow, new vulnerabilities arise and are exploited by hackers. Naturally, as they do, cybersecurity analysts, cybersecurity engineers, and the rest of the cybersecurity industry is growing in tandem to secure IoT devices and networks.

IoT stands for the Internet of Things.

Having IoT devices in your house or business can make life easier, but having them also presents another point of vulnerability through which someone with malicious intent can attack. IoT devices can be very vulnerable if not handled properly — which is why it is so important to secure them.

If you have an insecure IoT device in your home or business, an attacker can use this as an access point to your network. From here an attacker can gain valuable information about your network, your family, your organization, or yourself.

An IoT device is any device that can take in information and connect to other devices on a network to exchange this information. IoT devices can be helpful in a sense of convenience. They can allow you to control locks, doors, fans, cars, or even the temperature of your house.

A weak IoT device may create a vulnerable spot on your network for an attacker to target. If the attacker compromises this device, they can use it to attack other machines on your network, or even the network itself. A network (including your home wireless network) is only as secure as its weakest point.

Everyone should have an understanding of the types of threats IoT devices can pose if not properly secured. Everyone should know how to secure IoT devices and prevent attacks against their organization or home network.
