It's become commonplace to use multiple devices at home. I think there are many people who have Wi-Fi at home and are connected to the Internet. This article is about your home network.
First, try answering this question.
- Do you have Wi-Fi at home?
- Do you have more than one device connected to the internet?
- Have your friends or relatives ever come to your home?
- Is security perfect?
1. Protect your computer
The easiest way to secure your home network is to start by protecting your physical device. Computers, tablets and smartphones are devices that are susceptible to malicious intent through the Internet and software / apps. Software / apps can hide something, or they can be free but come with extra bonuses.
The best way to protect your device is to install a good security product. There are many high-performance products out there that have been reviewed by a trusted third-party evaluation agency. Prices vary and some are available for free. I recommend Kaspersky Security, which has a high degree of protection. This product is compatible with Windows, Mac, Android, and iOS and multiple operating systems. You don't just need a competent security product.
It's also important to always download the app from the official website (Google Play, Apple's App Store, or the official website of the app). If you download it from an unofficial website, you may install a version of the app with extra features. As a result, advertisements are displayed profusely, various information is stolen, traffic is jumped by being used for mining virtual currency without knowing it, and login information to bank accounts is stolen. It can be.
I introduced the Internet to my home, I think the vendor did the installation of the modem and router, and the setting of the user name and password. If you've kept your username and password set since then, change them. Wi-Fi may be used by someone outside.
Many routers have a default username and password. Often simple strings are used, such as "username: admin / password: admin" or "username: admin" / password: password. These default credentials can be found immediately by doing a Google search on your router's model name. If you know your router username and password, you can change the network name of someone else's home, set a new username and password, and change various settings. Change your username and password now. At the same time, update the firmware of the router.
In addition, set up a guest network for friends and relatives visiting your home. Specify a guest network credential that is different from the main network.
As with the router passwords mentioned earlier, many IoT devices have default passwords, and a Google search can easily find the default passwords. Try a Google search to find out what passwords are defaulted to your home device. If you still have the default password, change it now.
IoT device passwords are a problem because they can be used by cybercriminals. Increasing numbers of cases of infecting IoT devices with malware, adding them to botnets, and using them for cyber attacks are increasing at an alarming rate.
To avoid such a situation, it is a good idea to put a sticker on the lens of the camera. One option is to attach the webcam cover and remove it only when you want to use the camera. Some security products have the ability to restrict access to the camera. I personally recommend using this feature.
Have you ever found a USB stick somewhere? In a parking lot, a park, an office lobby, etc.? I think there are quite a few people who have picked it up somewhere. I often get a USB memory as a novelty item at an exhibition, and it's basically cheap, so no one is so worried about dropping it.
So what do you do if you find a USB stick? Do you want to plug it into your computer and check the contents? Do not do that! There is an English saying that curiosity is destructive, but it's not the only story. There is a risk that your computer will be infected with malware and that cryptocurrency miners will sneak in. Some may say that it's too much of a concern, but let's look back a bit. Not too long ago, in 2010, Iran's nuclear facility network was infected with a malware called Stuxnet via a USB stick.

Protect the Internet of Things (IoT) for smart devices
If you have a network-connected device (IoT device) connected to your home network, we recommend that you connect to the guest network instead of the main network. Also, change the default password on your device.As with the router passwords mentioned earlier, many IoT devices have default passwords, and a Google search can easily find the default passwords. Try a Google search to find out what passwords are defaulted to your home device. If you still have the default password, change it now.

4. Don't let me peep
There are many apps and websites that ask for permission to access your camera or microphone. For what? I can't be sure, but someone may be really watching you somewhere in the world.To avoid such a situation, it is a good idea to put a sticker on the lens of the camera. One option is to attach the webcam cover and remove it only when you want to use the camera. Some security products have the ability to restrict access to the camera. I personally recommend using this feature.
5. Keep USB threats away
There is one more thing I would like to mention. What can be a threat to businesses and to ordinary people like you and me ... about USB sticks.Have you ever found a USB stick somewhere? In a parking lot, a park, an office lobby, etc.? I think there are quite a few people who have picked it up somewhere. I often get a USB memory as a novelty item at an exhibition, and it's basically cheap, so no one is so worried about dropping it.
