42. Promiscuous Monitoring Of Wireless Networks #2 42

43. Questions #1 43 Explain : What Is The Difference Between Promiscuous And Non-Promiscuous Wireless Capture? ________________________________________________ ____ {T/F} Any Ethernet adapter can be used for promiscuous mode monitoring in a wired Ethernet network ____ {T/F} Any Wireless Ethernet adapter is equally good for strength, and other important statistics and indicators.

44. Questions #2 44 ____ {T/F} Standard drivers for wireless NICs support promiscuous mode ("RF Monitoring") While the adapter can receive radio signals on a given frequency regardless of the destination MAC address in the packet, the packets that are not addressed to this adapter are _?_ by the driver, and there is no way to make the standard driver pass them to the network monitoring software. _____ {T/F} A number of network monitoring software vendors make special RF monitoring drivers for all wireless adapters.

45. Questions #3 45 In order to do promiscuous packet gathering, the user must  obtained a supported wireless _?_,  install the wireless monitoring program,  replace the original driver by the special RF monitoring driver List the Make, Model, and Vendor Of All Wireless Adapters Made Available To You By Dr. Hicks. ______________________________________________

46. Questions #4 46 The Real Question : [ "Is there a RF monitoring driver for my Wi-Fi card and operating system?"] Do An Internet Search For Each Of The Adapters Listed On The Previous Slide. Adapter RF Monitoring Driver _________________________________ _______ {Y/N}

47. Questions #5 47 Software to do promiscuous packet gathering is called a W_?_ A_?_ Aside from the problems related to NIC drivers, wireless traffic is sometimes encrypted using WEP (an older standard) or WPA. A good WLAN Analyzer must be capable of _?_ encrypted network traffic on the fly utilizing a user-provided WEP or WPA-PSK key. A WLAN analyzer may not be required if all you need to monitor is the traffic between the wireless stations and the Internet. Using a standard, non-wireless monitor on a M_?_ port would make it possible to capture the packets being sent and received through the access point. A network layout illustrating this method is shown below.

48. Questions #6 48 Software to do promiscuous packet gathering is called a W_?_ A_?_ Aside from the problems related to NIC drivers, wireless traffic is sometimes encrypted using WEP (an older standard) or WPA.

50. Mirror Port Software 50

51. Questions #7 51 "How can I see all of the subnet traffic using Network Monitor?". The most efficient way to do this is to attach your computer's ethernet connection directly to the "_?_" port on your switch. On Cisco switches the mirroring port is called the _?_port and use a software program called a "Switched Port Analyzer". ____ {T/F} Almost all switches today come with one of these ports to allow system administrators to analyze network traffic using a packet sniffing product like Distinct Network Monitor.

52. Questions #7 52 Why do you need to attach to the mirror port? Well, technically when a NIC driver is in promiscuous mode, it is able to see all of the traffic that is travelling on the wire it is attached to. However, that traffic may be in fact limited to its _?_ traffic and _?_ broadcast traffic in the case of a switched network. As an administrator, the most efficient way for you to analyze traffic that is not visible from your computer is to capture it using the mirror or _?_port on your switch. When this is not possible Distinct Network Monitor does offer one more option through its Agents. Using Agents you will be able to analyze traffic that is not visible from your computer.
