How to secure your Wi-Fi connection? Guide to securing your wireless Network


1. Install a Firewall A firewall helps protect your PC by preventing unauthorized users from gaining access to your

computer through the Internet or a network. It acts as a barrier that checks any information coming from the Internet or

a network, and then either blocks the information or allows it to pass through to your computer.

2. Change the Administrative Password on your Wireless Routers Each manufacturer ships their wireless routers with a

default password for easy initial access. These passwords are easy to find on vendor support sites, and should therefore

be changed immediately.

3. Change the Default SSID Name and Turn off SSID Broadcasting This will require your wireless client computers to

manually enter the name of your SSID (Service Set Identifier) before they can connect to your network, greatly minimizing

the damage from the casual user whose laptop is configured to connect to any available SSID broadcast it finds. You

should also change the SSID name from the factory default, since these are just as well-known as the default passwords

4. Disable DHCP for a SOHO network with only a few computers consider disabling DHCP (Dynamic Host Configuration

Protocol) on your router and assigning IP addresses to your client computers manually. On newer wireless routers, you

can even restrict access to the router to specific MAC addresses.

5. Replace WEP with WPA WEP (Wired Equivalent Privacy) is a security protocol that was designed to provide a wireless

computer network with a level of security and privacy comparable to what is usually expected of a wired computer

network. WEP is a very weak form of security that uses common 60 or 108 bit key shared among all of the devices on the

network to encrypt the wireless data. Hackers can access tools freely available on the Internet that can crack a WEP key in

as little as 15 minutes. Once the WEP key is cracked, the network traffic instantly turns into clear text – making it easy for

the hacker to treat the network like any open network. WPA (Wi-Fi Protected Access) is a powerful, standards-based,

interoperable security technology for wireless computer networks. It provides strong data protection by using 128-bit

encryption keys and dynamic session keys to ensure a wireless computer network’s privacy and security. Many

cryptographers are confident that WPA addresses all the known attacks on WEP. It also adds strong user authentication,

which was absent in WEP.
