Most wireless networking devices will give you the option of broadcasting the SSID. While this option may be more convenient, it allows anyone to log into your wireless network. This includes hackers. So, don’t broadcast the SSID.
Wireless networking products come with a default SSID set from the factory. (The Cisco default SSID is “ciscosb”.) Hackers know these defaults and can check these against your network. Change your SSID to something unique and not something related to your company or the networking products you use.
Change your SSID regularly so that any hackers who have gained access to your wireless network will have to start from the beginning in trying to break in.

•Use the highest level of encryption possible
•Use “Shared Key” authentication

•User certificate: Personal Information Exchange (PKCS#12(.PFX))
