Cyber Warfare Boot Camp – Day 1: Beginning the Linux Journey

Objective: 

Students will begin preparing for proficiency in cyber security and information security techniques, technologies and methodologies.

Links:

Topics Discussed:

  • Curriculum Overview
  • Cyber Security
  • Linux
  • Linux History
  • GNU
  • GPL
  • Linux Distributions
  • Linux Kernel
  • Package Management
  • Rolling Release
  • Branches

Assignment:
  1. Visit the Arizona Cyber Warfare Range website. The AZCWR is a live fire cyber warfare range created to further the development of cyber security and information security skills for those who wish to develop such skills. Our goal this semester is to become proficient enough to tackle the challenges presented by the Cyber Warfare Range.
  2. Take a look at the Learning Resources page on the AZCWR website. These are the resources recommended by the AZCWR to gain the skills needed to take on the range, and these will form the backbone of our training this semester.
  3. The first step is to gain proficiency in Linux, as by its own admission, close to 100% of everything the AZCWR (and by extension, a large portion of systems that run the Internet) is done in Linux.
  4. We will begin by visiting the Linux Journey website, and we will walk through the online instruction modules together, learning about the history of Linux, and working our way through a few of the various distributions of Linux, noting the unique features of each and exploring the advantages and disadvantages presented by each flavor of Linux.
  5. Tomorrow, we will begin working with the Command Line Interface in Linux, and investigate a few important commands.

DIY Directional Antennas – Final Reflection

Objective:

I can complete my midterm assessment by demonstrating and evaluating what I learned during the DIY Directional Antennas Project.

Links:

DIY Antennas Project Final Reflection Form:

Google Classroom

Topics Discussed:

Wireless Networking
802.11 Wi-Fi spec
Directional Antennas
Waveguide Antenna
Yagi Antenna
Flickenger design Antenna

Assignment:

Today, we will complete our directional antenna project. Our goal was to sustain a 2.4 GHz Wi-Fi signal over a minimum distance of 100 yards (300 ft or ~92m). Many of the antenna designs successfully completed this task, but only one came out on top with a whopping -68db signal and 32% sustained signal quality over a distance of 150 yards. Please congratulate Luis and Eli for their outstanding helical antenna design that conquered all other designs. They will be enjoying pizza and wings on Friday as the rest of the class completes the final reflection assignment.

The link for the reflection assignment can be found here. Please follow the instructions on the form, and answer each question group with a complete five-sentence paragraph. Pay attention to your spelling, punctuation and grammar as you compose your paragraphs. This assignment is to be written in a professional tone in an academic voice, and it will be graded based on the criteria described on the form. Each team member must submit their own form, but can work together on the wording of the individual submissions. This assignment is effectively your final project assessment which represents the major portion of your project grade, and should be addressed accordingly.

Good luck, and thank you for all your hard work on this project. Do your best on your reflection and then it’s back to the lab for some Linux installation and configuration exercises!

Wireless Networking – DIY Directional Antennas Project: Revision Phase and Final Testing

Objective:

I can demonstrate my understanding of computer networks, network operating systems and wireless networking by assembling a directional antenna with the intent of establishing and sustaining a 2.4 GHz wireless signal at a distance of greater than 100 yards.

Topics Discussed:

802.11 Wi-Fi spec
Directional Antennas
Waveguide Antenna
Yagi Antenna
Flickenger design Antenna

Assignment:

Today, we will begin the final revision phase of our directional antenna project. Last week, two teams tied with equivalent dB gain readings on our test receiver router, but only one can win! Remember that the goal is to sustain a 2.4 GHz Wi-Fi signal over a minimum distance of 100 yards (300 ft or ~92m) and the winner will be the one who sustains the highest (negative) dB reading and signal quality over the longest distance.

We will conduct final tests the week of February 21st (Monday the 20th is a holiday!). To be considered a success (and receive credit for the project), your antenna design must be able to sustain at least a one-bar wireless signal over a 100 yard distance (the length of the football field). If your team is not present for the final test or you do not have a working antenna to test on Tuesday, February 21st, you will receive a zero on the second half of this project without the opportunity for make-up. (We’re only going out to the field once.)

Reminder: The team (or individual) that produces the antenna that can reliably sustain the highest gain signal over the longest distance will receive a personal pizza and wings party, to be held while everyone else writes a four paragraph personal reflection describing their participation in this project.

Good luck, and remember: Your antenna doesn’t have to be perfect, it just has to be better than everyone else’s.

Assignment:

Today, we will continue the build phase of our directional antenna project. Remember that the goal is to sustain a 2.4 GHz Wi-Fi signal over a minimum distance of 100 yards (300 ft or ~92m).

All tools and equipment are on the metal cart Room 212. The wireless network cards are located in the cabinet closest to the Teacher Workroom door in Room 212. If the cabinet is locked, see Mr. Herrera for the key. The transmitter testing cart is in the back of Room 225, and the username and password is on a stickynote at the bottom of the screen. The receiver cart (with the target router) is there as well, but will need a magnet instructor to log in with the admin password.

Please use this time to make progress on your project. On Friday, February 10th, we will go out to the football field and test all completed antennas to allow those with working products to see the results and modify their designs if necessary. You should have a finished antenna prepared to test at that time so you can tweak the design if necessary before the final test on the week of the 20th!

We will conduct final tests during the week of March 20th. To be considered a success (and receive credit for the project), your antenna design must be able to sustain at least a one-bar wireless signal over a 100 yard distance (the length of the football field).

Reminder: The team (or individual) that produces the antenna that can reliably sustain the highest gain signal over the longest distance will receive a personal pizza and wings party, to be held while everyone else writes a four paragraph personal reflection describing their participation in this project.
