The video discusses the convenience of a home network. Keeping your home network secure is becoming increasingly difficult as hackers turn their attention to the 'low hanging fruit'' which many home networks offer. Hackers can access your network and use it to download huge loads of data at great expense to you.
With a home network, you can share a single internet connection among several devices at once, like your computer, your tablet, or your smartphone. This is great for convenience and flexibility, but there are a few precautions you need to take to help keep your home network secure.
Why worry about home network security? The reason is, hackers can exploit your network in a number of ways. First up, they can piggyback on your network to get free internet access for themselves. This can use up your download quota and even slow down your connection. Hackers can use your network to install programs that go back out onto the internet to attack other computer systems.
What can you do to keep them out? Make sure your network is configured with a password. That way, no one can connect to your wireless network without your permission. When people try to connect, your network ask for the password. If they can't supply it, their computer won't be able to access your network, and therefore, the internet.
For an extra layer of security, you can set up a separate guest password on your network. This allows you to block visitors from parts of your network, like the personal files on your computer but still give them access to the internet, so that they can surf the web.
For even tighter security, you can configure your network to accept connections only from computers that it already knows. You do this on the router itself, and that's a small box that shares data between your internet connection and your computer. With your router configured this way, even if someone knows the wireless password, their computer won't be allowed to be connected to the network unless it's on the known computers list.
Another simple tip for home network security is to just turn it off when you're not using it. Without a network, it's impossible for anyone to access your computer remotely. If you don't want to be switching your network on and off all the time though, it's easy enough to create a secure home network. Set up correctly, it can help protect you from a range of possible threats and stop people freeloading off your internet connection.
