| Titre | How to Defend Your IoT Devices from IoT Botnets |
| Texte |
The Internet of Things (IoT) is changing how the world works. Machine to machine (M2M) communication simply makes for faster, more timely, and transparent connections, thereby saving us a lot of time and money.
This means that your doctor no longer has to wait a few hours to receive your heart monitor readings when it automatically transmits such information to your doctor’s computer or tablet.
It’s much easier for manufacturers and retailers to keep track of inventory when they receive real-time updates on remaining supplies.
At home, you’ll never forget to write something on your shopping list when your smart refrigerator updates that list for you.
In the hands of the right people, the IoT has great potential to improve quality of life. But some people have found a way to exploit the IoT for their own gain. They do this through the IoT botnet.
What is an IoT botnet?
To answer this, we first have to define what the IoT and botnet are.
The IoT is simply the wireless interconnection of devices (things) through the Internet. It basically means that devices such as phones, refrigerators, and heart monitors have a “switch” that lets them connect to the Internet.
On the other hand, a botnet is simply a network of computers infected with malicious software and controlled as a group without the owners' knowledge. These computers are then used to perform tasks like sending spam emails.
Now, if we put those two together, we’ll have a network of computers and other devices (things) connected through the Internet infected with malicious software being controlled without the owners’ knowledge. An IoT botnet is, therefore, much more intrusive and dangerous than a regular botnet.
An example of IoT botnet attacks includes the large botnet network discovered when a fridge was caught spreading spam emails. Another example was Mirai botnet which was used to perform DDoS attacks on French hosting firm OVH. A final example involved the enslavement of 18,000 Huawei devices in one day!
So, how can you defend your IoT devices from an IoT botnet?
Well, I’ve got some bad news and good news for you. The bad news: IoT devices and cybersecurity aren’t necessarily a match made in heaven. This is because IoT devices are designed to be open to the Internet (and, therefore, to anyone who can access their connection).
The good news: you can improve your IoT devices’ security yourself by trying the following steps.
1. Do your research
Before you buy any IoT device for your home or company, do a little digging online. See if your prospective purchase has built-in security features. Look for any exploits and vulnerabilities that may become concerns in the future.
Don’t just rely on the product’s Official Site. Trawl through forums (like Reddit) for user reviews on the product. These reviews come with invaluable information |
