We are using wireless connections for internet browsing and file sharing. Many of the home and office have wireless connection for networking. Since the wireless network uses radio signals to transmit data, it may be more vulnerable to intrusion and security problems. Like signals from cellular and cordless phones, wifi signals can also be intercepted. So we needs to take care about wireless security.
Steps to protect your wireless network
1. Change the wireless network name (SSID) from the default
The network name SSID (Service Set Identifier) it has a default value for wireless devices installed by the manufacturer. The SSID is the name of your wireless network, which can have up to 32 characters. Hackers know these default names and can use them to log into your network. Change the network name to something unique, not associated with your network equipment.
2. Change the default password
When using wireless devices like access points and routers, in order to connect and manage their settings will require a password. They have a default password. (The default password is usually admin). Hackers know these defaults and will try to use them to access the wireless device and change settings. To prevent unauthorized changes change the device default password, so it is hard to guess.
3. Turn on the MAC-address filtering
Almost in routers you can enable MAC address filtering (MAC = Media Access Control). MAC address is a unique number assigned to each network device. When the MAC-address filtering is configured, only devices with specific MAC addresses can access the wireless network. For example, you can allow access to the wireless network only for the computers in your home.
4. Turn on encryption
Encryption protects data transmitted over a wireless network. There are Different levels of security for wireless networks such as the WEP protocol (Wired Equivalent Protocol) and WPA (Wi-Fi Protected Access). Currently, the most widely used is WPA since it is more secure because it uses dynamic key encryption.
These steps help you to protect wireless network from external access. Secure your network and enjoy the browsing.
