How to secure WiFi network – Is my network secure
Each year, there are more than 1.5 million cyber attacks around the world. If you don’t want to be one of the victims, read this tutorial on how to have a secure WiFi network.
Change the name of your home wireless network
The SSID (Service Set Identifier) or Wireless Network Name of your Wireless Router is usually pre-defined so changing your WiFi’s name makes it harder for malicious hackers to know what type of router you have.
Use a name you can remember and identify, as the SSID has no influence on the security of your network (not even if you choose not to broadcast it).
Create a unique password for your router
Is my network secure ? Well, is your network protected by a strong password?
The first step for your network security is to ensure that your password is strong enough.
Access your router’s wireless settings, usually by entering 192.168.1.1 in your browser, and change your password to a long enough and secure enough one.
Enable network encryption
Have you ever wondered that “is my network secure ?” One of the ways to ensure network security is through network encryption.
Network encryption means you encrypt your WiFi signals, so that other computers will not be able to connect your network.
There are several encryption methods such as, WEP, WPA (WPA-Personal), and WPA2 (Wi-Fi Protected Access version 2). Since WEP is the basic encryption method, it is the least secure and it is not a good idea to use it.
To enable encryption on your Wireless network, open the wireless security settings on your router’s configuration page. Then you can select security method you wish to use. It is advisable to use WPA/WPA2-PSK.
A firewall can help secure to your WiFi network
Firewalls aren’t just software programs. They can also be a hardware. A hardware firewall is somehow the same as a software one, and its biggest advantage is that it adds an extra layer of security. most of the best wireless routers come with a preinstalled hardware firewall and Even if your router doesn’t have one , you can install a good firewall device to your router.
Filter MAC addresses
One of best ways to safeguard your network is through MAC filter. All your wireless devices have a unique MAC address just like every computer connected to the Internet has a unique IP address. You can add the MAC addresses of all your devices to your wireless router’s settings so that only the specified devices can connect to your WiFi network.
The bottom line is that securing your wireless network is very important because if you don’t, your neighbors can not only borrow your Internet connection, but also access your files. Make sure that your network is always secure.
