A WiFi Network has now become an inevitable part of our techy life — for we don’t like to mess up with wires much and mobile data drains your Smartphone battery like hell! If we take the case of an organization, the whole chain for internet access is done through WiFi networks. It is because of these reasons you need to secure your WiFi network for a variety of advantages: your network won’t be used by others, your bandwidth is solely yours and it’s a big-enough layer of protection for your privacy! In this post, however, we have some tips you can use to secure WiFi network. We hope it helps you to create a far more secure and reliable home or office network.
Never Leave it Open
Unless you trust your neighbors and strangers that much, you should never leave the network in the open state. When a WiFi network is open, anyone can access it; there will be no prompt for a password or something. Therefore, you will not know if someone has used your network to commit a legal offence or something and the end of it, you are going to get punished. So, we repeat, even if you trust who is around you, never make your WiFi network accessible to the public.
Choose the Best Network Encryption
Well, once you have decided not to leave it open, you have different kinds of network encryption standards to select from. There is WEP, WPA, and WPA2 etc, which range in terms of the protection offered. The third one offers two sub-divisions — one with TKIP and another with AES, both offer unique modes of encryption using 128-bit keys. So, it needs to be noted that WPA2 is the most secure network encryption standard you can choose.
What happens in most cases is that people tend to choose WEP Encryption, which of course asks a password. But, its strength is comparatively lower and can be compromised using BackTrack or that kind of tools available. So, we say it again, you should use the best encryption when you set up the network. If you’re using a device that’s manufactured before 2006, there might be some compatibility issues though. By the way, even when you use WPA2 encryption, it’s essential to use a complex-enough, non-guessable password that you — only you — could remember.
Well, in the business scenario, you can create a different network for guests if you want to give them net access. It’s the better thing to do, you know.
Choose a Wise SSID and Router Password
The problem of having a guessable SSID and router credentials is that your network security and data are subjected to a theft along with bandwidth. So, instead of using the default router credentials combo of router — details of which are available in web — you should change it to a complex one.
Another thing you can do to secure WiFi Network of yours is to choose a not-easily-identifiable SSID (which is a name of the wireless network). There are even some options to hide the SSID from results, but the better one is to choose a unique one. Though it may seem silly, this change can have a big impact on the security of the network.
Use MAC Filtering
This is one of the most effective methods of securing a WiFi network, by limiting the devices that can be connected to the network. As you know, each device has an MAC address — your computer, Smartphone, tablet PC or any other device that can be connected to the internet. In the router dashboard, you can add the MAC address of the device you’d like to get connected. This method is effective when you are creating a wireless network for your home or that kind of small purposes. If you are a person who changes devices quite frequently, this is going to be a hassle.
Update Your Router Firmware
Well, let us tell that first: this is a bit of nerdy thing to do! But if you take the courage and effort to do that, it’s going to give you an extremely secure WiFi network. There are two options available — you can either upgrade to official upgradable firmware offered by your router manufacturer or you can choose to go with some third-party firmware such as Tomato or DD-WRT. The most important factor about this upgrade is that you get better performance as we come to the case of network strength; you also get some customization options on the router, which is a good thing. For instance, if you are using a third-party firmware, you will be able to adjust the output of your router, such as to limit the range to your bedroom or hall.
Having all these said, it’s a fact that no wireless network is perfectly secure! Nevertheless, following the steps we’ve mentioned above will have an awesome impact on WiFi security settings, we bet.
