Wireless Security

Wireless networks can provide small businesses with an easy way to extend their networks reach, without high costs. Wireless networking provides small businesses with many advantages including flexibility, increased collaboration, and extending point of sale; however, if wireless access points (devices where your company computers connect to the Internet without having to be attached to a cable) are not secured correctly they provide attackers with easy entry into your company’s network. In fact, many companies use wireless over wired networks. You can place many computing devices in a garage or a room and not need to worry about wiring or cabling….the whole wireless thing is like magic at least on the surface.

Securing your wireless network does not require a large amount of resources or time. By following these simple suggestions, you can significantly increase your security for your wireless access points.
• Deploy business class equipment
• Change the default administrator password and change your password often
• Change Service Set identifier (SSID) of the access point does. Make sure the SSID does not include your company name or is easily linked with your company; establish a naming convention that makes it less likely that your access point will draw the attention of unwanted individuals. Most of us in the business even do this at home, picking a random collection of numbers and letters.
• Using strong encryption - Industry-standard Wi-Fi Protected Access (WPA) or WPA2 is only
• Set up separate WLAN (SSID/VLAN)-Could be used to segment different user groups for higher level security policies
• Ensuring management ports are secured-Use Simple Network Management Protocol v3 (SNMPv3), Secure Shell (SSH), or Secure Sockets Layer (SSL) to secure management interfaces to the wireless network.
