Protect your home network and your smart devices

The stuff on the Internet can be very unsafe. Threatpost announces news about the damage caused by malicious applications every day. So it is pretty clear that security issue is a big problem for many consumers.

Protect your home network and your smart devices

The Internet of Things (IoT)

IoT has one feature, which is a bit sad – only the manufacturer of the device can deal with its security issues, while the consumer cannot do anything, in most cases.

Let’s take a smart kettle, for example.  

Imagine that it appears that your smart kettle is spreading out spam, which participates in distributed-denial-of-service, also known as DDoS, attacks. The smart kettle does not send spam initially – it was infected with the virus, which turned your kettle into a part of a botnet. The kettle got infected with malware, possibly because its manufacturer chose to establish Wi-Fi connection in the kettle but did not set up a protection for it.

So, what can you do to protect your smart devices?

Kaspersky IoT Scanner

This dedicated app was created in order to make it easier for consumers to spot exposures in Wi-Fi devices.[1]

This Android IoT Scanner is capable of analysing your home network and discovering all the connected devices in order to disclose common vulnerabilities.

So, when you install the IoT Scanner, it scans your home network and lists all of the devices connected to it. Furthermore, the app scans particular network ports and identifies, which of those ports are accessible and which are not.

If the scanner finds out that there are devices with open ports that may be exploited, the application will warn and prompt the consumer to close those open ports.

However, there are two issues:

Firstly, the IoT market is highly diverse and it is impossible to establish a step-by-step manual for the whole range of devices. In order to protect smart devices, consumers have to find a user manual for the device, which was detected with an open port, and look for information on how to close it.

Secondly, there are some devices that do not allow closing ports. So, in this case, we would advise you to double think whether you really want or need this smart device at home because it can be potentially hacked. But it’s up to you if you want to keep it; IoT Scanner only discloses you potentially vulnerable spots and allows you to make the final decision.

Furthermore, there are two more beneficial features in Kaspersky IoT Scanner.

The app reveals and lists all the devices that are connected to your Wi-Fi network, so you can see if there are any unwanted devices that use your Wi-Fi. You can see if there is a person behind, and whether he is stealing bandwidth or even spying on you. The scanner also empowers you to remove the unwanted device from your network through the user interface.

If there is a new device connected to the network, the app will also discover it and will scan the ports of that device – the scanner will notify you about all of the unnecessarily accessible ports. This feature will also notify you when a new device is connected to your network and reveal how safe it is immediately.

Check out the Kaspersky IoT Scanner on Google Play. It is free!
