A random person shows up at your place: a mailman, a milkman, an insurance salesman, a friend, a friend’s friend or a family member. You talk to them for a little while and then they ask if they can come into your home, and you show them every corner of it, including where you keep your family pictures, your IDs and where you keep the money. Do you? No, because that would compromise your security, wouldn't it? No? You really don’t care?
Well, maybe we don’t do that (very often) but we share our home network everytime a guest shows up. But, what does that have to do with compromising security? you may ask. Well, that’s another wrong question.
Most of the time, our gadgets share private information over the network, because every device connected to your home network is trustworthy, isn’t it? Look, I’m not saying you shouldn’t trust your family or friends, what I’m saying is: if you want to keep it tight, you should definitely look “Computer Security” up. A term which here means the protection of data, networks and computing power (Davis, 2015).
Sometimes, we’re just too confident with how we handle our sensitive information and home networks, and that’s why we should study Computer Security. Some ways to stay safe is to create a guest network and to change our Wi-Fi passwords regularly to avoid others from breaking in or infiltrating our networks, and get access to our files.
Also, if you’d like to know who’s connected to your Wi-Fi network, you can use this really helpful app called Fing.
Fing is a network scanner to detect intruders, and solve network issues easily. You can download it for Android and for iOS.
