Don't forget about protecting mobile clients

Your Wi-Fi security concerns shouldnundefinedt stop at your network. Users with smartphones, laptops and tablets may be protected on site, but what about when they connect to Wi-Fi hotspots or to their wireless router at home? You should try to ensure their other Wi-Fi connections are secure as well, to prevent intrusions and eavesdropping. Unfortunately, it isnundefinedt easy to ensure outside Wi-Fi connections are secure. It takes a combination of providing and recommending solutions and educating users on the Wi-Fi security risks and prevention measures.


  • Don't use WEP
  • Don't use WPA/WPA2-PSK
  • Do implement 802.11i
  • Do secure 802.1X client settings
  • Do use a wireless intrusion prevention system
  • Do deploy NAP or NAC
  • Don't trust hidden SSIDs
  • Don't trust MAC address filtering
  • Do limit SSIDs users can connect to
  • Do physically secure network components
  • Don't forget about protecting mobile clients
