In the information age, it's more and more important to protect our personal information. But even if your network is secure and your information is safe, you still have to worry about the potential for threats such as cyberbullying.
Wi-fi is a bit of a different beast than wired communication. With a wire, the signal is protected: It travels from the port to your device, with no chance for people in between to see what's being sent. Wireless signals are sent over the open air. This means that these connections are far more vulnerable to being hacked by people between the router and the device.
You may even be connecting to an attacker's device directly, rather than a router, allowing them to channel the Internet through their device and take whatever information they find interesting. Even with your own home router, people who can get access to your connection may be able to view your personal files, take your passwords, or even do things that are illegal using your network, making you part of the crime.
Fortunately, we have ways to keep ourselves safe that do a great job at protecting our information and safety. The easiest step is to secure your network. This means encrypting your network so the data being sent is scrambled, so anyone who could get access to it won't be able to understand it.
Even if your technology is secured as much as possible, your information can still be at risk online, just because you put it there. One of the best ways to not have personal information leaked online is to not put it online in the first place. A huge amount of personal information that's out on the Internet was put there by people filling out their social media profiles.
It's also important to regularly search for yourself in search engines to make sure that no information is there that you don't want to be there.
Another important thing to think about when keeping yourself safe online is cyberbullying. This is like the bullying kids might experience at school, except that it happens online. You can't always prevent this from happening, and it's not the victim's fault when it does. But you can fight it by reporting the messages to the websites they use, blocking them on websites and apps, and not responding to them.
