Security Threats Facing Wireless Networks
Wireless networks are easy to find. Hackers know that in order to join a wireless network, wireless networking
products first listen for “beacon messages”. These messages can be easily decrypted and contain much of the
network’s information, such as the network’s SSID (Service Set Identifier). Here are the steps you can take:
Change the administrator’s password regularly. With every wireless networking device you use, keep in mind that
network settings (SSID, WEP keys, etc.) are stored in its firmware. Your network administrator is the only person
who can change network settings. If a hacker gets a hold of the administrator’s password, he, too, can change
those settings. So, make it harder for a hacker to get that information. Change the administrator’s password
regularly.
