Wireless LANs are prone to attacks (Wireless LAN Attacks) especially because of their open transport medium (air!) and easy availability of cheap attack tools. An unsecured wireless LAN does not only invites attacks but can also become the source of malicious activities, say for example, a hacker upon gaining entry into the corporate wireless LAN can use the mail-server to send numerous unsolicited emails. So, continuous monitoring of the wireless LAN and enforcing wireless LAN security policies are of prime importance. WiFi Manager with dedicated RF Sensors and web based gui makes this entire process of wireless LAN monitoring and security lot simpler.
RF Sensors are hardware Wi-Fi sensors which helps monitor the RF spectrum. They capture the 802.11 packets within their range, correlates and analyzes them to identify various security threats, which includes -
-
Identifying the vulnerabilities in the network
-
Identifying and mitigating the various DoS attacks and intrusion attempts
-
Discovering and blocking the rogue Access points and rogue mobile clients
-
Analyzing the RF traffic for spurious activities etc.
-
RF Sensors distributed across the wireless network monitors the wireless traffic within their range, analyzes it and forward data to the centralized WiFi Manager Server.
-
At the WiFi Manager Server the data is further analyzed and the processed information is archived and also presented to the wireless LAN Administrator via a web interface in a user friendly way as alerts, graphs etc.
- Unpack the Sensor from the box, which includes the Sensor main unit and an external power adapter
- Connect an Ethernet cable from the Sensor to a hub or switch that connects to the Server.
- Plug in the power supply and connect it to the Sensor. It is important to use the correct power supply for the Sensor. Connecting a different
power supply can damage the Sensor and become a fire risk. - Check the Power light; initially, it displays a red light. After a brief delay, the LAN light should illuminate green.
- Check the LAN indicator, if it does not illuminate, the Ethernet cable might not be connected or the cable type is incorrect.
