How to Secure a Wireless Network in 5 Simple Ways

Learn How to Secure a Wireless Network in 5 Simple ways. Does your Wi-Fi is encrypted with WEP, SSID is hidden and the beam enabled MAC address filtering ? So do you think no one else can connect to your network? Your Wi-Fi is safe? not true. Not really.

How to secure a wireless network in 5 simple ways

Having a good Wi-Fi security is simple: You have to enable WPA (ideally WPA2) and set a strong password. Other safety tips can be put aside, because if they can deter malicious users, a strong password encrypted with WPA2 deter everyone.

How to Secure a Wireless Network in 5 Simple Ways

1. WEP Encryption

There are several ways to encrypt a wireless network, including WEP, WPA and WPA2. Routers that are sold today, the cheapest, still use WEP encryption. If your router allows you to use WPA encryption, you must use it.

WEP encryption can be cracked very easily. And while encryption prevents, anyone can connect directly to our network, anyone who can see it also may determine your password.

Instead of using WEP, make sure you use WPA. If you have WPA2, even better. If you have some old device, which has no WPA, as the original Xbox or Nitendo DS, you probably already have updates if you provide this encryption.

2. Hidden SSID

The SSID is the identifier of a wireless network. It is used to identify each packet that is transmitted over the network. All wireless devices attempting to communicate with each other must share the same SSID. In summary, the SSID is the name of the network.

Many routers allow you to hide the SSID of your wireless network. However, the names of wireless networks were not designed to be hidden . If you decide to hide your SSID and connect to it manually, your computer is constantly broadcasting the network name and searching. Even if you are in another city, your laptop will have no idea if your network is close and continue searching. Apparently, this solution does not seem efficient.

3. Filter MAC addresses

Each network interface has a unique ID known as MAC (Media Access Control address).Your laptop, Smartphone, Tablet, video game console, any computer that supports a wireless connection has its own MAC address. Your router will probably show a list of MAC addresses connected and lets you restrict network access by MAC address. In this case, you could connect all your computers to the network, enable MAC address filtering and allow only the computers that are connected to the network access.

However, this solution is not entirely robust. Persons who may see your network can use a sniffer and sniff the traffic of your Wi-Fi network and view the MAC addresses of computers that are connecting . Finally, just change your MAC address for a few who have allowed access and can connect to your network, assuming you know the password.

MAC address filtering can give us some security benefits, but we must not become complacent. Increase the difficulty that someone can access our network, but using a WPA2 encryption system is currently the best option.

4. Static IP addresses

Another safety tip that can be read over there revolves around using static IP addresses.By default, our router provides us with a built-in DHCP server. When connecting a computer or other device to the wireless network, the computer asks the router for an IP address and the DHCP server assigns a IP.

Well we could disable this option (DHCP server) and any team that now try to connect to your network, you can not receive IP address automatically. You will have to enter the IP address by hand on each computer that uses the network.

There is no valid argument for this security . If anyone can connect to your wireless network, it will be easy for you to set a static IP address on your computer. Besides this tip is ineffective, the discomfort increases when setting our wi-fi network.

5. Weak passwords

Finally, and most important. The weak passwords are always the main security risk. If you are using WPA2 encryption to your Wi-Fi network you may think that you are safe, but not so. Passwords of type 0000, 1234, abc123, etc. They are as bad as WEP or worse.

I recommend you do not use the minimum number of characters that you are asked to set the password . Moreover, to have a strong password,it should be between 15 and 20 characters, but of course, you could always use a password longer than 63 characters if you want. For these cases, people often use phrases or sequence of words as a password.

Conclusion

Assuming you’re using WPA2 encryption with a strong password, and you can feel confident that no one can access your Wi-Fi network. No need to worry about hiding the SSID, MAC address filtering and IP address used to secure your network.
