Luckily, in choosing their topics, students will likely have begun to identify resources they can use in completing their project. Point out that the written component is quite short. Let students figure out how to use it on their own. This Code of Practice is written for engineers and engineering management to support their understanding of the issues involved in ensuring that the safety responsibilities of an organization are addressed, in the presence of a threat of cyber … Sharing/Submission: You may want to collect students’ one-pagers, have them share in small groups, or with the whole class. If you have a degree in another area but want to join … You may optionally pause here to recap and go over terms if you like or just let students proceed (see activity part 2 below). freeCodeCamp is a donor-supported tax-exempt 501(c)(3) nonprofit organization (United States Federal Tax Identification Number: 82-0779546) Our mission: to help people learn to code for free. Closest matches are shown first. Emphasize the need for clarity in their writing, and remind them that everything must fit on a single page. Don't rush it, but don't linger on cracking caesar ciphers. Sockets layer/transport layer security (SSL/TLS). We use encryption everyday on the Internet, primarily to conduct commercial transactions, and without it our economy might grind to a halt. These cyberattacks are usually aimed at accessing, changing, or destroying sensitive information; extorting money from users; or interrupting normal business processes.. cybersecurity. Since students were researching something of their own choosing, they might be eager to show what they found out. Differences from the actual Explore PT: The actual Explore Performance Task will be completed over 8 class hours. 20 minutes). Conducting Your Research: This document is intended to serve primarily as a guide to students for identifying online sources of information. You might choose to send them directly to that at this point or show the video to the whole class. The tasks laid out for students in code studio are: After some exploration time regroup to clarify what the tool is and how it works. These are critical skills students must use when describing the computing innovation they will research. But, as mentioned in the video, a large percentage of cybersecurity vulnerabilities are human-related, such as choosing bad passwords, (unintentionally) installing viruses, or giving personal information away. Show: The Internet: Cybersecurity and Crime - Video. Showing top 20 occupations for cyber security. Longer passwords increase the number of possible keys making it, Encryption is essential for every day life and activity, The "strength" of encryption is related to how easy it is to crack a message, assuming adversary knows the technique but not the exact "key". Computational tools dramatically increase the strength and complexity of the algorithms we use to encrypt information, but these same tools also increase our ability to crack an encryption. Experiment with the tool - Click things, poke around, figure out what it's doing. What about a random substitution cipher? The video touches on a number of topics that students might choose to research later: Distribute: Give students copies of Rapid Research - Cybercrime - Activity Guide A virus is program that runs on a computer to do something the owner of the computer does not intend. In this lesson, students are introduced to the need for encryption and simple techniques for breaking (or cracking) secret messages. Make sure you reinforce this definition as students choose their topics. Was it difficult to crack a Random Substitution cipher? If you received a notification letter and 25-digit PIN code … Students come in with various backgrounds and leave with the training and skills they need to excel as cybersecurity professionals. The instructions for this activity are simple - there is no handout: Goal: Select a message encrypted with a caesar cipher and use the provided widget to "crack" it. How much easier is it to crack a Caesar cipher than a random substitution cipher? The annotations given here should provide enough depth for the kinds of responses expected of students. shorter? Typically a virus installed on many computers (thousands) activate at the same time and flood a target with traffic to the point the server becomes overwhelmed -- doing this can render web services like DNS, or routers, or certain websites useless and unresponsive. Implementing cybersecurity has software, hardware, and human components. Simple substitution ciphers give insight into encryption algorithms, but as we've seen fall way short when a potential adversary is aided with computational tools...our understanding must become more sophisticated. Remember the letters aren't randomly substituted - the alphabet is just shifted. As usual: you can't break it. Give students about 5 minutes to get into the tool and crack a few messages. For more than 65 years, NSA’s signals intelligence and cybersecurity missions have given the U.S. a strategic advantage over adversaries as a combat support agency. We've annotated them with brief explanations that should come out during discussion. “Encryption” is a process for transforming a message so that the original is “hidden” from anyone who is not the intended recipient. See how codes can protect your online secrets and what motivates hackers to hack. Code.org ... My name's Jenny Martin and I'm the Director of Cybersecurity Investigations at Symantec. Digital commerce, business, government operations, and even social networks all rely on our ability to keep information from falling into the wrong hands. We are a national non-profit providing services and support for women and marginalized groups interested in a cybersecurity career. Then you'll research a particular cybercrime and quickly prepare a one-pager about it. Do the students have any questions for you. The new version of the widget you'll see is a more sophisticated version of the encryption tool that shows you lots of different stuff. Cyber Video Quizzes. Presenting and cracking a caesar cipher should go pretty fast. Understand the relationship between cryptographic keys and passwords. If you are interested in licensing Code.org materials for commercial purposes, The Internet: Encryption & Public Keys - Video. As a resource, you may wish to read all of Chapter 5 of Blown to Bits. Choosing Your Cybercrime Event: It is recommended that you place a time limit on this process (e.g. With tools it becomes trivial, as we'll see next. Do you trust the security of your email, text messages, and browser history? Following this lesson you may opt to either run the research activity in the next lesson or move on to running the full Explore PT with your class. Today cybercrime causes huge problems for society. Definitions of cryptography, encryption, decryption, cracking/breaking an encryption, cipher, etc. A "firewall" is simply software that runs on servers (often routers) that only allows traffic through according to some set of security rules. Typically a thief trying to trick you into sending them sensitive information. Experts. Well, probably within the last hour, if you’ve sent an email or logged onto a website. If necessary provide context of some facts about the Internet: Secrecy is a critical part of our lives, in ways big and small. Ops 401: These are the most intense courses offered at Code Fellows. If they have responded completely to each of the prompts, it is fine to write less. Make games, apps and art with code. Did it take longer than you thought? The Rapid Research activity features vocabulary, concepts, and skills that should help prepare them for the AP Explore PT, and also serves as a capstone for the sequence of lessons on encryption and security. If we are to create a secure Internet, we will need to develop tools and protocols which can resist the enormous computational power of modern computers. Any encryption cipher is an algorithm for transforming plaintext into ciphertext. What jobs are they interested in, what are their favorite tech gadgets or apps, and how do they think they are built? Get students into to the tool without much or any introduction, Give students working in partners a fixed amount of time (5 minutes or so) to poke around and see if they can figure out what it does and doesn’t do – typically this might be presented as a mystery worth investigating, Teacher fill in any gaps or explanations of how the tool works afterwards, Have students click to the next bubble to see the frequency analysis version of the widget. The prompts are similar in style and content to prompts students have already seen. If you are running out of time, assigning some of these terms for homework might be a good way to review and kick off the next day. Once you've done one, it only takes a matter of seconds to do others.
