How To Secure Your Wireless Network
People have more flexible time due to​ wireless network .​
Thanks to​ the​ invention of​ wireless .​
People can now work from home while taking care of​ their kids or​ doing house works .​
No more stress from traffic jam anymore .​
is​ this great?
Well, there is​ something you should realize .​
Working from home while using a​ wireless local area network (WLAN) may lead to​ theft of​ sensitive information and​ hacker or​ virus infiltration unless proper measures are taken .​
As WLANs send information over radio waves, someone with a​ receiver in​ your area could be picking up the​ transmission, thus gaining access to​ your computer .​
They could load viruses on to​ your laptop which could be transferred to​ the​ company's network when you go back to​ work .​
Believe it​ or​ not! Up to​ 75 per cent of​ WLAN users do not have standard security features installed, while 20 per cent are left completely open as​ default configurations are not secured, but made for​ the​ users to​ have their network up and​ running ASAP .​
It is​ recommended that wireless router/access point setup be always done though a​ wired client .​
You can setup your security by follow these steps:
1 .​
Change default administrative password on wireless router/access point to​ a​ secured password.
2 .​
Enable at​ least 128-bit WEP encryption on both card and​ access point .​
Change your WEP keys periodically .​
If equipment does not support at​ least 128-bit WEP encryption, consider replacing it .​
Although there are security issues with WEP, it​ represents minimum level of​ security, and​ it​ should be enabled.
3 .​
Change the​ default SSID on your router/access point to​ a​ hard to​ guess name .​
Setup your computer device to​ connect to​ this SSID by default .​
4 .​
Setup router/access point not to​ broadcast the​ SSID .​
The same SSID needs to​ be setup on the​ client side manually .​
This feature may not be available on all equipment .​
5 .​
Block anonymous Internet requests or​ pings .​
On each computer having wireless network card, network connection properties should be configured to​ allow connection to​ Access Point Networks Only .​
Computer to​ Computer (peer to​ peer) Connection should not be allowed .​
Enable MAC filtering .​
Deny association to​ wireless network for​ unspecified MAC addresses .​
Mac or​ Physical addresses are available through your computer device network connection setup and​ they are physically written on network cards .​
When adding new wireless cards / computer to​ the​ network, their MAC addresses should be registered with the​ router /access point .​
Network router should have firewall features enabled and​ demilitarized zone (DMZ) feature disabled .​
All computers should have a​ properly configured personal firewall in​ addition to​ a​ hardware firewall .​
You should also update router/access point firmware when new versions become available .​
Locating router/access point away from strangers is​ also helpful so they cannot reset the​ router/access point to​ default settings .​
You can even try to​ locate router/access point in​ the​ middle of​ the​ building rather than near windows to​ limit signal coverage outside the​ building .​
There is​ no guarantee of​ a​ full protection of​ your wireless network, but following these suggested tips can definitely lessen your risk of​ exposing to​ attackers aiming at​ insecure networks.
