Most people have WiFi in their homes right now, but if you’re not really a tech enthusiast, have you put much thought into securing it?
There are a few potential security issues with WiFi. Firstly, you should make sure that your router is secure, so that if someone does get on your network somehow, they can’t easily access the router and change the configuration in a way that could cause inconvenience for you. To do this, connect to the router’s admin panel, and change the login details from the defaults. If you don’t know the details, pick the router up and look on the underside – there is a good chance that the username and password will be printed there.
Next, change the SSID – if your current SSID includes the name of the company that supplies your Internet connection, or the brand name of the router, then you should change it immediately to something generic sounding instead. This will ensure that it is that little bit harder for a would-be hacker to identify what type of device they are trying to connect to. Some people tell their router to not broadcast the SSID at all, but this makes it harder to connect to the network.
In addition, make sure that the connection is ‘secured’, so that people have to enter a passcode to connect. Unsecured connections allow anyone on, and this can put your network at risk because once a device is on the network they may be able to access other devices on the network as well (and, for example, see the files that you have shared, or snoop on unencrpyted traffic).
There are a few different connections to choose from – the most common being WEP, WPA and WPA-2. Of those, WEP is the least secure. It will deter people who are just passing by your house and hoping to ‘quickly check their emails’ from even trying to connect, but it would not stop a dedicated attacker. WPA is slightly more secure, and WPA2 is the most secure.
Choose a password that you can remember, but that is not one of the most common passwords. You have a good degree of flexibility with WPA2, so you can pick something that is not easy to guess. Change the passwords periodically so that you don’t have to worry about them being brute forced.
Update your router’s firmware if you are confident enough in your skills to do that (or get a tech-savvy friend to do it for you), and, if you have a Windows Phone or tablet, make sure that you have turned off WiFi password sharing – this is something that will share passwords with your friends, and it could inadvertently lead to your password being leaked to a lot of people (if it is shared with their friends, and so on). The actual passwords don’t become public knowledge, but it means that in theory strangers could be able to get connected to your network.
