Shawn Jackman (Jack) CWNE#54 is a personal friend and has been a mentor to me for many years. I've had the pleasure and opportunity to work with Jack for 4 years. Jack is a great teacher who takes complex 802.11 standards and breaks them down so almost anyone can understand the concept at hand. I'm excited for you brother. Great job and job well done! Put another notch in the belt!

Are you new to wireless security and never heard of Aircrack-ng ??
Aircrack-ng is a network software suite consisting of a detector, packet sniffer, WEP and WPA/WPA2-
PSK cracker and analysis tool for 802.11 wireless LANs. It works with any wireless card whose driver supports raw monitoring mode (for a list, visit the website of the project or [1]) and can sniff 802.11a, 802.11b and 802.11gtraffic. The program runs under Linux and Windows; the Linux version has been ported to the Zaurus and Maemo platforms, and a proof-of-concept port has been made to the iPhone.
Aircrack-ng 1.1Aircrack-ng 1.1 is released ;)
A lot of bug fixes (including the buffer overflow in different tools) and improvements have been done. The most noticeable changes are the addition of airdrop-ng by TheX1le and the interaction in airodump-ng.

So what is the difference between a small x and a capital X ? Let’s first look how the IEEE assigns the numbers we reference everyday…. Let’s pick on 802.11 and 802.3, shall we.
802 = PROJECT
First , you have the 802 (PROJECT). This is the ROOT level of the tree. We reference 802 as part of 802.3
and 802.11 standards all day long. Think of 802 as the root / base of the tree.
802.11 or 802.3 = WORKGROUPS
Under the 802 project the IEEE assigns something called “workgroups”. A workgroup is formed to solve certain issues. These are the folks that create the STANDARDS, key word here STANDARDS. Standards created by the workgroup always references capital letters, should there be a letter in the standard *cough* 802.1X
Let’s look at two standards.
802.3 = Ethernet Standard
802.11 = Wireless Standard
802.11n or 802.3af = TASK GROUP
Under the STANDARD you have something called TASK GROUPS. So the standard was defined and as needs arise and modifications are needed to the standard (also referenced as amendments), tasks groups are formed. Task groups start with a single lower case letter and sequentially progress a,b,c,d,etc.
For example, the 802.11 STANDARD was created and a TASK GROUP called ‘a’ was formed, also called the 802.11a amendment.
(Note: once all the single letters are used, an additional letter will be applied. For example 802.3af)
So break it down ….. 802.11n = WHAT?
(802 = PROJECT + 11 = WORKGROUP + n = TASK GROUP)
BACK to 802.1X
802 is the project, of course. We just covered that …
1X is the WORKGROUP that created the 802.1X standard. The standard is ALWAYS referenced with a capital letter, in this case X. 802.1X IS THE STANDARD, as there isn't any amendments. So if you answered: Capital X, you are correct!
