How to Secure a Wireless Network

 

There may be little harm in jumping into another person's Wi-Fi network uninvited, but what happens when someone with bad intentions enters an unsecured Wi-Fi network? The loss of personal and financial information could be devastating. Computer owners need to learn how to secure a wireless network.


WEP and WPA Encryption

Encryption represents the best defense for securing a wireless network, as it encodes data transmitted from the laptop or desktop computer to the wireless router. Wireless Protected Access (WPA) provides better encryption security than the older standard called Wireless Encryption Protocol (WEP). WPA possesses keys that often change, making the keys virtually impossible to hack. Create a strong password that includes both letters and numbers. Search for a wireless router that supports both the WPA and WPA2 modes, which provide stronger encryption and enhance WPA wireless adapter capability.


Change Router Defaults

Change the wireless router's factory presets, such as administration login number and password. Make sure the changes do not reflect anything an intruder can easily associate with you, such as a pet name or favourite music group. Moreover, change the Service Set Identifier (SSID), which many router manufacturers name after the computer component company. Wireless network owners do not want to use the manufacturer's default settings. Identity thieves and other perpetrators of invasive attacks on your wireless network know most manufacturer router default settings.


Switch Off SSID Broadcasting

SSID operates as a broadcast message that notifies wireless network users of a wireless network's presence to any device located within range of the network. Every wireless router offers users a way to turn off the SSID broadcast. By turning the broadcast off, hackers do not know about your wireless network. They prefer to attack networks that appear on the SSID broadcast. However, remember that older routers have trouble connecting to wireless networks, when the SSID does not broadcast signals.


Permit Access Based on MAC Addresses

Every wireless network device, from laptops to notebooks, comes with a unique number that identifies the device. The Machine Access Code (MAC) allows users to filter access to wireless routers. By filtering access to a wireless router, a wireless network user can only accept access to electronic devices the user has preapproved. All other devices do not have permission to enter the wireless network. Thus, hackers and identity thieves cannot access the wireless router, which represents the best way to violate a wireless network security system.
