Assignment:

Hello, and congratulations! You successfully made it to the end of Networking and Operating Systems 1-2H! I hope this was a fun and productive class for you, and that you learned a few things that will help you in your future endeavors.

If you could take a moment to let me know how I did, and how I can improve for future classes, I have attached a brief questionnaire on the Google Classroom page. It’s not for a grade, but your feedback will help me out a lot, and I’d appreciate it if you took a moment to fill it out with your honest opinions.

Now that we’re done, above all else:

  1. Use your powers for good, not evil. Remember the lessons of Spider-Man: “With great power, comes great responsibility.” You now have skills and abilities far beyond those of your average computer user. Use them to protect and defend, never attack.
  2. Keep using your skills! Take more computer classes and keep learning as much as you can about PC, Mac and networking technology. The more you use your knowledge, the less likely it will slip from your memory. The more you know, the more effective and valuable you are, and as more devices connect to the global network, Technical Support and Network Security especially will remain rapidly growing and highly lucrative fields for decades to come.
  3. Do what you love, and you’ll never work a day in your life. If you love working with computers and technology, then pursue it. If computers are just your hobby, don’t make it a job – it’ll just suck the joy out of your hobby. If you truly love working with computer hardware and software and networking technology, and you love solving problems with technology, then by all means pursue a career in the Computer Science field. As long as you love what you’re doing, every day you’ll look forward to going to work and the financial rewards will follow.

It has been my great pleasure to accompany you on your journey into Networking and Operating Systems this year. I hope that you enjoyed this class, and continue to use your newfound powers to solve the problems that are related to and created by technology, and to protect your own and others’ computer systems from the constantly emerging and evolving range of threats – both online and offline.

  4. If you do not finish the competition during class time (and it is highly likely that you will not), 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 Play
The Regular Season 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 11:00 am MST on Friday, April 13th and ends at 7:00 p.m. MST on Sunday, April 15th.

This is the big game – the one we’ve been preparing for. Get a good night’s rest, eat your Wheaties (or Lucky Charms, if that’s how you roll), and be here at 10:15am on Friday to get logged in to the NCL Stadium, and be ready to compete. Use all your knowledge, training and skills to do your very best, and we’ll discuss the results after this weekend. Good luck, and may the Force be with you! Always.

Cyber Warfare Boot Camp – Week 7: Network Troubleshooting in Linux

Objective: 

Students will continue preparing for proficiency in cyber security by reviewing networking fundamentals.

Links:

Topics Discussed:

  • Network Basics
  • OSI Model
  • TCP/IP Model

Cyber Warfare Boot Camp – Week 5: Network Config in the Linux CLI

Objective: 

Students will continue preparing for proficiency in cyber security by reviewing networking fundamentals.

Links:

Topics Discussed:

  • Network Basics
  • OSI Model
  • TCP/IP Model
  • Network Addressing
  • Network Configuration
  • Network Interfaces
  • Network Manager
  • route Command
  • dhclient Command
  • ARP
Assignment:
  1. Visit the Linux Journey website and scroll down to the “Networking Nomad” section. Click on the “Network Config” item.
  2. Network Configuration is how you set up your network. In Windows, much of this is done for you by the OS. Linux will do this for you if you want it to, but if you want to get hands-on with the interfaces and routing options, then there are many tools within the CLI that will let you do so.
  3. Read through the module to discover how to view and manipulate network interfaces, routing tables, DHCP leases, ARP caches and view network settings using the Network Manager tool.
  4. Don’t forget to get signed out for Advisory tomorrow to participate in the AZ Cyber Warfare Range hacking activity with David Hernandez! It’s going to be a 90 minute activity, so you’ll want to get started during Advisory to participate in the whole thing!

  • Routing
  • Switching
  • Flooding
  • Routing Table
  • Routing Protocols
Assignment:
  1. Visit the Linux Journey website and scroll down to the “Networking Nomad” section. Click on the “Routing” item.
  2. Routers are the “traffic cops” or “post office” of networks, depending on what metaphor you choose to follow.

Cyber Warfare Boot Camp – Week 4: Subnetting

Objective: 

Students will continue preparing for proficiency in cyber security by reviewing networking fundamentals.

Links:

Topics Discussed:

  • Network Basics
  • OSI Model
  • TCP/IP Model
  • Network Addressing
  • Subnetting
  • Subnet Mask
  • Octet
  • Host
  • IP Address Classes
Assignment:
  1. Visit the Linux Journey website and scroll down to the “Networking Nomad” section. Click on the “Subnetting” item.
  2. Subnetting is one of those things that you do with a calculator in the real world, but you’re not going to be allowed to take a calculator with you if you take a test like the Network+, CySA+ or CCNA exams, so you better learn how to do it on your own.
  3. The “Subnetting” section of the Linux Journey website gives you a quick explanation of what subnetting is, and how it works. It also provides a subnet math cheat method that should get you through most of the problems you’ll encounter. However, if you want a more thorough understanding of how it works (and trust me, you do) visit the Subnetting.net link for further details.
  4. The “How to Subnet” page at Subnetting.net provides a thorough overview of what subnetting is and how it works. If you’re too lazy to read the page (and I know most of you are) you can watch the Subnetting Tutorial video series, and get a full explanation of what subnetting is, how it works, and how to figure out subnets without the need for a calculator.
  5.  With the materials provided here, you should be able to achieve a strong foundation in subnetting, which will allow you to handle a good portion of the questions on the CCNA and Network+ certification exams, as well as have a strong understanding of how packets figure out how to travel from one host to another, even when they’re on very different networks.
