November 7, 2013 instructor WLAN Checkpoint
For a business setting up a WLAN security is very important and should be top priority. If you do not secure your WLAN you are opening your business up to hackers that can ruin your business. Before you set up the WLAN a site survey should be done. This will determine what level of exposure your company is at and help decide how much security is needed.
Of the many ways to protect your WLAN you should start with changing all the default passwords on all your equipment. If you have a small business without many users and devices a MAC filtering system is a good choice. MAC filtering is where every MAC address for all devices allowed on the system are listed and if a device tries to get onto the system that is not on the list it will not be allowed. That is why smaller systems can keep up with this type of format.
Another way to protect your WLAN is with WPA (WI-FI Protected Access). WPA is an upgrade to the WEP(Wired Equivalent Privacy). WEP regulates access to wireless network through a devices hardware-specific MAC address.
After the site survey is done and the security measures are determined and implemented a business should feel confident in their WLAN. This being said, there is no such thing as a perfect security system and you should always be diligent and frequently check your system to make sure the security protocols set in place are still working for your business.
