Cyber Security 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
  • Advantages/Disadvantages of Linux
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.

National Cyber League Resources: Cryptography Links

Links:

Decode Ingress – A list of tools that can help you with decoding  passcodes, originally provided for use with the AR game Ingress. Tools for text manipulating, basic conversions like text to ASCII, HEX to Base64. Tools to decipher Morse code.  Good Image exif info grabbers, and image editing tools for Steganography puzzles (messages hidden in digital images). A range of great info and tools about various ciphers, and their implementations.

Tools for Noobs: Online Decryption Tool – Decrypts a string using various algorithms (e.g. Blowfish, DES, TripleDES, Enigma).

Rumkin Deciphering Tools – This is a page dedicated to simple text manipulation tools, which all can be replicated with just paper and pencil. An amazing resource for deciphering methods, including many that we will definitely encounter in NCL puzzles (Atbash, Railfence and Vigenere).

MD5hashing.net Encryption and Decryption – At md5hashing.net you can hash (encrypt) any string into 66 different hash types. As you probably know – decryption of any hash is impossible, but they offer reverse decryption via our database (~1000M records, and counting).

Splitbrain.org Encoding/Decoding Tools – This tool helps you to quickly run some text through various different encoding/decoding functions available in PHP. Great for a lot of different decoding possibilities rapidly

CodeBeautify.org Encryption/Decryption Tool – A nice, clean tool for decrypting codes that you know the key for, or encrypting codes with your own original key.

SQLite Viewer for Chrome – Chrome plugin for viewing SQLite databases in your browser. Allows opening and editing of SQLite databases without requiring admin access to install.
