Home Wireless Network Security Issues
Running a​ business from home has its advantages, including no commute, a​ more accommodating work schedule, fresh coffee and​ home-cooked meals at​ any time you want.
But running a​ business from home using a​ home wireless local area network (WLAN) with your computer may lead to​ thievery of​ confidential information and​ hacker or​ virus penetration unless proper actions are taken .​
As WLANs send information back and​ forth over radio waves, someone with the​ right type of​ receiver in​ your immediate area could be picking up the​ transmission, thus acquiring access to​ your computer.
Here is​ a​ list of​ things that you should consider as​ a​ result of​ implementing a​ home wireless network setup used your business:
Viruses could be loaded onto your laptop which could be transferred to​ the​ company's network when you go back to​ work.
Up to​ 75 per cent of​ home wireless network WLAN users do not have standard security features installed, and​ 20 per cent are left completely open as​ default configurations and​ are not secured, but are made for​ the​ users to​ have their network up and​ running ASAP.
It is​ recommended that home wireless network router/access point system setups be always done though a​ wired client.
Always change the​ default administrative password on your home wireless network router/access points to​ a​ secured password.
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.
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.
Setup router/access points so as​ to​ not broadcast the​ SSID .​
The same SSID needs to​ be setup on the​ client side manually .​
This feature may not be available on all equipment.
Setup your home wireless network router to​ block anonymous internet requests or​ pings.
On each computer having a​ wireless network card, network connection properties should be configured to​ allow connection to​ Access Point Networks Only .​
Computer to​ computer (peer to​ peer) connections should not be allowed.
Enable MAC filtering .​
Deny connection to​ wireless network for​ unspecified MAC addresses .​
MAC or​ physical addresses are accessible through your computer device wireless 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.
Your home wireless network router should have firewall features enabled and​ demilitarized zone (DMZ) feature disabled .​
Periodically test your hardware and​ personal firewalls using Shields Up test available at​ www.grc.com .​
All computers should have a​ properly configured personal firewall in​ addition to​ a​ hardware firewall.
Update router/access point firmware when new versions become available.
Locate router/access points away from strangers so they cannot reset the​ router/access point to​ default settings .​
Also, locate router/access points in​ the​ middle of​ the​ building rather than near windows to​ limit signal coverage outside the​ building.
You should know that nothing is​ 100% .​
While none of​ the​ actions suggested above will provide full 100% protection, countermeasures do exist that will help .​
The good collection of​ suggested preventative actions contained herein can help you deter an​ intruder trying to​ access your home wireless network .​
This deterrant then makes other insecure networks easier targets for​ the​ intruder to​ persue.
