National Cyber League Week 2: The Preseason Game

Objective: 

Students will use their accumulated knowledge and training to compete in the NCL Preseason Game.

Links:

Topics Discussed:

  • Cyber Security
  • National Cyber League
  • NCL Spring Season
  • Preseason

Assignment:

The First Game: Preseason Play
The Preseason is a week-long mandatory game. You must participate in the Preseason in order to receive an NCL Scouting Report. The Preseason gameplay starts at 1:00 p.m. ET on Monday, April 1st and ends at 9:00 p.m. ET on Sunday, April 8th.

There are lots of preparatory materials available. Also, be sure to read about the Bracketing system, which the Preseason game determines, as well as the Ethical Behavior/Rules of Conduct.

  1. If you complete the Preseason game, continue your training in the Gym to prepare for the Regular Season competition on Friday, April 12th.
  2. Remember that Thursday, April 4th and Friday, April 5th are a split schedule due to AIMS Science testing. You will not be here on Thursday, but you will have two solid hours to complete NCL challenges on Friday, so please use your time wisely.
  3. If you do not finish the competition during class time, please continue to advance through the challenges over the weekend. Do not forget that you can log into the NCL Stadium from any device with an Internet connection, but you may need tools available on a Windows or Linux workstation to solve some of the challenges. It is recommended that you continue with the competition over the weekend and get as far as you can to achieve the best result in your final Scouting Report.

The Big Game: Regular Season Individual Game
The Regular Season Individual Game is a three-day mandatory game. You must participate in the Regular Season in order to receive an NCL Scouting Report. The Regular Season Game starts at 10:00 am MST on Friday, April 12th and ends at 6:00 p.m. MST on Sunday, April 14th.

Please mark your calendars, and plan and prepare accordingly as the Preseason and Individual Game will form the bulk of your grade for this final term.

Support Team:

For those who are not competing in the NCL challenges, a daily challenge will be posted on my Google Classroom page. These will usually come in the form of short quizzes or short answer response posts. Visit the page and complete the daily challenge to receive your participation points for the class!

Cyber Security Boot Camp – Wireshark Packet Analysis Activity

Objective: 

Students will continue preparing for proficiency in cyber security with an introduction to the basics of packet analysis in the Wireshark application.

Links:

Topics Discussed:

  • Kali Linux
  • Wireshark
  • Packet Analysis
  • Wireshark Configuration

Assignment:

  1. Capture packets on your eth0 interface for a period of five minutes. Visit https://netop.mistermarmolejo.com to get some http traffic going during the packet capture.
  2. Save the packet capture as a .pcapng file with today’s date, and upload it to today’s assignment post on Google Classroom to complete the activity by end of day tomorrow.
  3. If you are not sure how to begin a packet capture on the eth0 interface, review Professor Messer’s Wireless Packet Analysis video and read Lifewire.com’s How to Use Wireshark: A Complete Tutorial.
  4. If your Kali Linux Virtualbox installation is still not working, see Mister Marmolejo for assistance.

Cyber Security Boot Camp – Wireshark Packet Analysis 2

Objective: 

Students will continue preparing for proficiency in cyber security with an introduction to the basics of packet analysis in the Wireshark application.

Links:

Topics Discussed:

  • Kali Linux
  • Wireshark
  • Packet Analysis
  • Wireshark Configuration

Assignment:

  1. Continue working with Wireshark. This powerful packet collection and analysis tool is free to download and is pre-installed in the Kali Linux distribution.
  2. Watch Professor Messer’s Using Protocol Analyzers video to get a more in-depth introduction to the features of Wireshark.
  3. Review the good Professor’s Wireless Packet Analysis video and read Lifewire.com’s How to Use Wireshark: A Complete Tutorial to get a better idea of how the Wireshark interface works, and a few tips on how you can configure the Wireshark GUI to meet your specific needs and preferences.
  4. Note: Our Virtualbox installs of Kali use emulated network interfaces, which means that our wireless interface will not work like the one Professor Messer demonstrates in his video.
  5. Wireshark will, however, be able to analyze the packets being sent over the emulated hard-line network interface. Try running a packet capture on your en0 network interface and see what you can see! Run a packet capture, then visit a few websites, then filter the port 80 traffic to get an idea of what kind of information can be gathered by an analysis of the packets. We will discuss the results tomorrow.

  2. Both teams will be tasked with configuring their router to form two interconnected subnetworks, each supporting 24 hosts. Team 1’s network will be supplied Internet access from the school’s gateway. Team 2’s subnetwork will be required to receive Internet access from its connection with Team 1’s router.
  3. Each team will have to work together to correctly configure its router, but both teams will have to work together to form the links between the two networks.
  4. Use all the materials we have studied and the links I have provided above to set up and configure the network to the required specifications by end of day on Friday, February 22nd!
  5. All team members will be expected to participate, and pay close attention to the router configuration, as there will be a quiz on the details of the finished router configuration next week (i.e. Network Name, First Useable IP, Last Useable IP, Subnet Mask and Broadcast Address).
