However, even with the security features turned on, many hackers can crack the built-in security. Almost all Wi-Fi hardware has its security features turned off by default, so when a user installs an unauthorized rogue access point, it can act as an open door into an otherwise well-protected network. It is important to make sure your probe choice offers complete troubleshooting functionality to make certain all relevant tools are at your disposal for remote troubleshooting and diagnostics.īecause of inherent WEP security flaws, once a hacker can authenticate himself onto a Wi-Fi network, he can do everything from surf the Web to access confidential company information. Remote probes will take the hide-and-seek out of troubleshooting and provide total network visibility - all from an administrator's desktop. If a problem erupts in an area where a probe is located, the administrator simply clicks on the probe and gets instant visibility into that section of the network - without the expense and time related to travel. Probes collect data - both historical and real time - and report back to the analyzer console at the main site. Truly distributed protocol analyzers can also help IT monitor those infrequently visited remote offices or remote areas on a large network using remote probes.
Long-term tracking: For capacity planning and growth accommodation. Ongoing troubleshooting: This is helpful once a WLAN is in place and when, for example, users can't associate with an access point, find rogue access points or have general day-to-day communication troubles.ģ. Implementation: Where site survey of signal strength can help determine access point placement and optimal station locations Ģ. Protocol analyzers will include data on everything from wireless network vital signs to the latest statistics, errors and speed by station, and wireless triggers and alarms (to detect errors and intrusions).ġ. A few minutes after finding a wireless signal, a hacker with a protocol analyzer can view company data including e-mail and passwords.īy using a protocol analyzer with wireless support, administrators can identify problem traffic and decode WEP encrypted traffic. Hackers are taking to the streets with laptops in their cars to go "war driving" to find these exposed networks. While Wi-Fi technology is typically meant for users inside a building, it also broadcasts the wireless signal onto the street. Hackers use these products to locate security holes in networks, while network administrators use them to detect security holes and prevent breaches.
This tool captures traffic on a medium (wired Ethernet or wireless signals in the air), breaks it down according to established rules and displays results for a network administrator to evaluate. Ironically, the one tool that network administrators and hackers have in common is a protocol analyzer.
